However, this method does not provide a good reference for whether the centers of the end product and the product to be press-fitted are aligned. The operator is required to perform manual adjustments through visual and tactile inspections, and the adjustment time is relatively long. Eccentric assembly is very likely to occur, thereby affecting the press-fitting quality and performance of the product. Summary of the invention

When the sensor detects that the end product is placed on the pressing device and the product to be pressed is placed on the supporting device, a pressing signal is generated and sent to the pressing system.

[0008] Among them, in step S810, after placing the end product on the pressing device and placing the product to be pressed on at least one set of supporting devices, it also includes: S814: the operator presses the start button to generate a pressing signal and send it to the pressing system.

[0010] Before step S810, the method further includes: S840: acquiring data information of the product to be press-fitted and sending it to the press-fitting system, and controlling the supporting device to adjust to a supporting height suitable for the product to be press-fitted.

[0011] Among them, at least one adjustment device includes a horizontal adjustment device and a vertical adjustment device. When the detection device detects that there are both horizontal errors and height errors between the product to be pressed and the end product, step S820 includes: S821: based on the horizontal error detected by the detection device, using the horizontal adjustment device to adjust the horizontal position of the product to be pressed and the end product in the horizontal direction; S822: based on the height error detected by the detection device, using the vertical adjustment device to adjust the height position of the product to be pressed and the end product in the vertical direction.

[0014] Among them, in step S822, using the vertical adjustment device to adjust the height position of the product to be pressed includes: S8222: controlling the second fine-tuning drive to push the horizontal slider to move in the horizontal direction, driving the vertical slider and the connecting plate to move in the vertical direction to adjust the height of the support assembly and the product to be pressed.

[0015] Among them, step S830 includes: S831: controlling two groups of pressing devices to move towards each other, so as to press the end products on each group of pressing devices onto the corresponding ends of the products to be pressed, so as to complete the pressing; or, S832: first controlling one group of pressing devices to move toward the adjusted products to be pressed, so as to press one of the end products onto one end of the products to be pressed, and then controlling the other group of pressing devices to move toward the products to be pressed with one end product, so as to press the other end product onto the other end of the products to be pressed, so as to complete the pressing.

[0016] In the above scheme, before pressing, the end product on the pressing device is used as an alignment reference, and the alignment accuracy between the product to be pressed and the end product is detected by using a detection device. If they are not aligned, at least one adjustment device in each group of supporting devices is used to adjust the product to be pressed in the corresponding direction, so that the product to be pressed is aligned with the end product in the corresponding direction, avoiding displacement and misalignment between the product to be pressed and the end product, thereby improving the pressing quality of the product.

[0029] The scheme of the embodiment of the present application is described in detail below in conjunction with the drawings of the specification.

[0030] In the following description, for the purpose of explanation rather than limitation, specific details such as specific system structures, interfaces, and technologies are provided to facilitate a thorough understanding of the present application.

For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the objects associated before and after are in an "or" relationship. In addition, "many" in this article means two or more than two. In addition, the term "at least one" in this article means any combination of at least two of any one or more of a plurality of, for example, including at least one of A, B, and C, can mean including any one or more elements selected from the set consisting of A, B, and C.

[0032] See also Figure 1 , Figure 1 It is a structural schematic diagram of an embodiment of the press-fitting system 100 of the present application. The press-fitting system 100 includes: an equipment body 110, two groups of press-fitting devices 120, at least one group of supporting devices 130 and a detection device 140. The two groups of press-fitting devices 120 are arranged on the equipment body 110 at intervals, and are slidably connected to the equipment body 110, and are used to support the end products and control the end products to be pressed onto the end of the product to be pressed. At least one group of supporting devices 130 is arranged between the two groups of press-fitting devices 120, and is slidably connected to the equipment body 110, and is used to place the product to be pressed. Each group of supporting devices 130 includes at least one adjusting device, and each adjusting device corresponds to a direction, and is used to adjust the alignment of the product to be pressed with the end product in the corresponding direction. The detection device 140 is arranged on the supporting device 130, and is used to detect the alignment accuracy of the product to be pressed and the end product. Among them, the detection device 140 can be a laser alignment device or an infrared sensor, etc., which is not specifically limited here.

[0033] The press-fitting system 100 of the present application can be applied to the fields of the power industry, metal processing industry, automobile manufacturing, etc. Before press-fitting, the detection device 140 is used to detect the alignment accuracy of the product to be press-fitted and the end product, so that the adjustment device is used to adjust the alignment of the product to be press-fitted with the end product in the corresponding direction, and then the two sets of press-fitting devices 120 are controlled to move toward each other, so as to press-fit the end product on the press-fitting device 120 onto the end of the product to be press-fitted supported by the support device 130. For example, in the power industry, the press-fitting system 100 is used to press-fit the flange onto the end of the insulating tube. For another example, in the metal processing industry, the press-fitting system 100 can be used to press-fit the sleeve onto the gear core shaft.

[0034] The two sets of press-fitting devices 120 may both be provided with end products, or one of the two sets of press-fitting devices 120 may be provided with end products and the other may not be provided with end products. When the other of the two sets of press-fitting devices 120 does not have end products, a flexible material may be provided on the side of the press-fitting device 120 that does not have end products and faces the product to be press-fitted, so as to protect the product to be press-fitted during the press-fitting process and prevent the product to be press-fitted from being squeezed and damaged.

[0035] An adjusting device is provided on the supporting device 130. Therefore, in order to better press-fit the end product and the product to be press-fitted, a centering adjusting component 121 can be provided on the pressing device 120. The centering adjusting component 121 is provided on the pressing device 120, and is used to adjust the end product to the center position of the pressing device 120, and then adjust the product to be press-fitted on the supporting device 130 with the end product as the alignment reference, so that the center of the end product and the product to be press-fitted are aligned.

[0036] See also Figure 2 Each group of supporting devices 130 also includes a supporting assembly 131 and a connecting plate 132. The supporting assembly 131 is connected to the connecting plate 132, and the supporting assembly 131 is used to support the product to be pressed.

[0037] In some embodiments, the support assembly 131 includes a support base 1311 and a mounting substrate 1312, and the support base 1311 is disposed on the mounting substrate 1312. Specifically, the support base 1311 may be a V-shaped support frame for supporting the product to be press-fitted, and an inverted V-shaped clamping device may be disposed above the support device 130 for cooperating with the V-shaped support frame during press-fitting to clamp and fix the product to be press-fitted to avoid displacement of the product to be press-fitted during press-fitting. It is understandable that the support base 1311 may also be a support frame of other shapes, such as a semicircular support frame, etc., to fit the shape of the product to be press-fitted and achieve better support.

[0038] Furthermore, in order to improve the application scope of the press-fitting system 100, the support base 1311 is a detachable device, and different support bases 1311 can be replaced for different products to be press-fitted.

[0039] In some embodiments, the mounting base plate 1312 of the support assembly 131 may be connected to the connection plate 132 via a guide post 133 .

[0040] Please continue reading Figure 2 , at least one adjusting device includes a horizontal adjusting device 134 corresponding to the horizontal direction. Figure 2 The horizontal adjustment device 134 includes: a mounting plate 1341, a first fine-tuning driving member 1342, a transmission assembly 1343 and a first guide rail 1344. The mounting plate 1341 is arranged above the connecting plate 132, wherein a hollow area is arranged in the middle of the mounting plate 1341 for passing the guide column 133, so that when the support assembly 131 moves in the horizontal direction, the guide column 133 has a corresponding moving space. The first fine-tuning driving member 1342 is arranged on the mounting plate 1341, and is used to drive the connecting plate 132 to move in the horizontal direction. For example, the first fine-tuning driving member 1342 can be a fine-tuning hand wheel. The transmission assembly 1343 is arranged below the mounting plate 1341, connected to the first fine-tuning driving member 1342, and is used to transmit the output power of the first fine-tuning driving member 1342 to the connecting plate 132, so as to drive the supporting assembly 131 connected to the connecting plate 132 to move. The first guide rail 1344 is fixedly disposed at the bottom of the mounting plate 1341, and the connecting plate 132 is connected to the first guide rail 1344 via a slider 1345. The first fine-tuning driving member 1342 can be connected to the transmission assembly 1343 via a connecting shaft (not shown).

[0041] Specifically, the transmission assembly 1343 includes a first bevel tooth 13431, a bearing seat 13432, a second bevel tooth 13433, a screw rod 13434 and a screw nut 13435. The first bevel tooth 13431 is arranged below the mounting plate 1341, the first bevel tooth 13431 is connected to the first fine-tuning drive member 1342, the bearing seat 13432 is arranged at the bottom of the mounting plate 1341, the second bevel tooth 13433 is arranged on the bearing seat 13432, the first bevel tooth 13431 is meshed with the second bevel tooth 13433, the screw rod 13434 is connected to the second bevel tooth 13433, the screw nut 13435 is movably connected to the screw rod 13434, and the screw nut 13435 is fixedly connected to the connecting plate 132.

[0042] The power output by the first fine-tuning driving member 1342 is transmitted to the first bevel gear 13431, and the first bevel gear 13431 transmits the power to the second bevel gear 13433 meshing therewith, and the second bevel gear 13433 transmits the power to the screw rod 13434 to rotate, thereby driving the screw nut 13435 to move on the screw rod 13434. The connecting plate 132 is fixed to the screw nut 13435, so when the screw nut 13435 moves, it will also drive the connecting plate 132 to slide on the first guide rail 1344, thereby driving the supporting assembly 131 connected to the connecting plate 132 to move in the horizontal direction, thereby adjusting the horizontal position of the product to be pressed, so that the product to be pressed is aligned with the end product in the horizontal direction.

[0043] In this embodiment, the first fine-tuning driving member 1342 can be a manual adjustment device or an automatic adjustment device. When the first fine-tuning driving member 1342 is a manual adjustment device and the detection device 140 detects that the product to be pressed and the end product are not aligned in the horizontal direction, the operator applies a force to the first fine-tuning driving member 1342 to drive the first fine-tuning driving member 1342, thereby transmitting the force to the connecting plate 132 through the transmission component 1343 in a mechanical way. When the connecting plate 132 moves in the horizontal direction, it will also drive the supporting component 131 connected thereto to move in the horizontal direction, thereby adjusting the horizontal position of the product to be pressed supported by the supporting device 130, until the detection device 140 detects that the product to be pressed and the end product are aligned in the horizontal direction, and the operator stops applying a force to the first fine-tuning driving member 1342. When the first fine-tuning driving member 1342 is an automatic adjustment device, the detection device 140 is used to detect whether the product to be pressed and the end product are aligned in the horizontal direction. If not, the detection device 140 sends a signal to the control unit in the pressing system 100, and the control unit sends a driving instruction to the first fine-tuning driving member 1342. After receiving the driving instruction, the first fine-tuning driving member 1342 will output power, and the output power will be transmitted to the connecting plate 132 through the transmission component 1343. When the connecting plate 132 moves in the horizontal direction, it will also drive the supporting component 131 connected to it to move in the horizontal direction, so as to adjust the horizontal position of the product to be pressed supported by the supporting device 130, so as to automatically adjust the alignment accuracy between the product to be pressed and the end product. When the detection device 140 detects that the two are aligned, it sends a signal to the control unit in the pressing system 100, and the control unit sends a stop driving instruction to the first fine-tuning driving member 1342.

[0044] See also Figure 3, at least one adjusting device includes a vertical adjusting device 135 corresponding to the vertical direction, and the vertical adjusting device 135 includes: a lifting screw 13511, a worm lifting assembly 13512 and a driving assembly 13513. The lifting screw 13511 is fixedly connected to the support assembly 131, and is used to control the lifting and lowering of the support assembly 131. The worm lifting assembly 13512 is arranged at the bottom of the connecting plate 132, connected to the lifting screw 13511, and is used to control the rotation of the lifting screw 13511. The driving assembly 13513 is connected to the worm lifting assembly 13512, and is used to provide power to the worm lifting assembly 13512. Among them, the driving assembly 13513 can be a power source such as a cylinder, a servo motor, etc., which is not specifically limited here.

[0045] In some embodiments, in order to better adjust the position of the product to be pressed so that it can be accurately aligned with the end product, at least one adjustment device in the support device 130 includes a horizontal adjustment device 134 and a vertical adjustment device 135. Figure 4 The horizontal adjustment device 134 is used to adjust the product to be pressed to be aligned with the end product in the horizontal direction, and the vertical adjustment device 135 is used to adjust the product to be pressed to be aligned with the end product in the vertical direction.

[0046] Please refer to Figure 1 , the press-fitting system 100 includes two groups of support devices 130, and a detection device 140 is arranged near each group of support devices 130. One of the two groups of support devices 130 can be provided with a horizontal adjustment device 134 or a vertical adjustment device 135, or a horizontal adjustment device 134 and a vertical adjustment device 135 are arranged at the same time. Similarly, the other of the two groups of support devices 130 can also be provided with a horizontal adjustment device 134 or a vertical adjustment device 135, or a horizontal adjustment device 134 and a vertical adjustment device 135 are arranged at the same time, as long as the two groups of support devices 130 can cooperate with each other to adjust the position of the product to be press-fitted. Therefore, how to set and layout the adjustment device on the support device 130 can be determined according to the alignment adjustment requirements of the product to be press-fitted and the end product. Therefore, it can be understood that the support devices 130 in the press-fitting system 100 can be three groups, four groups, five groups..., and the adjustment devices arranged on each group of support devices 130 can be different or the same, which is not specifically limited here.

[0047] In other embodiments, the vertical adjustment device 135 corresponding to the vertical direction in at least one adjustment device may have other structures besides the above structures. Figure 5The vertical adjustment device 135 includes a second fine-tuning drive member 13521, a tilting slider assembly 13522 and a base plate 13523. The connecting plate 132 is connected to the base plate 13523 through a guide column 13524. The second fine-tuning drive member 13521 is arranged on the base plate 13523. The second fine-tuning drive member 13521 is connected to the tilting slider assembly 13522. The tilting slider assembly 13522 is fixedly connected to the base plate 13523. The tilting slider assembly 13522 is slidably connected to the connecting plate 132.

[0048] Among them, the second fine-tuning driving component 13521 can be a fine-tuning hand wheel, a motor, etc., which is not specifically limited here.

[0049] Specifically, the tilting slider assembly 13522 includes: a second guide rail 135221, a horizontal slider 135222, a tilting guide rail 135223 and a vertical slider 135224. The second guide rail 135221 is arranged on the bottom plate 13523; the horizontal slider 135222 is connected to the second guide rail 135221, the second fine-tuning driving member 13521 is connected to the horizontal slider 135222 through a push rod, and the second fine-tuning driving member 13521 is used to push the horizontal slider 135222 to move on the second guide rail 135221; the tilting guide rail 135223 is tilted on the side of the horizontal slider 135222; the vertical slider 135224 is connected to the horizontal slider 135222 through the tilting guide rail 135223, and the vertical slider 135224 is connected to the bottom of the connecting plate 132. Through the limiting and guiding function of the guide column 13524, the position of the vertical slider 135224 fixed to the connecting plate 132 in the horizontal plane remains unchanged, so it moves in the vertical direction along the inclined guide rail 135223, thereby converting the horizontal movement into the vertical movement. In this way, the vertical space can be saved, and the vertical slider 135224 moves closely to the inclined guide rail 135223 due to the effect of gravity, and the movement is more stable, which helps to accurately adjust the height of the product to be pressed in the vertical direction and ensure that the product to be pressed is aligned with the end product in the vertical direction.

[0050] In some specific embodiments, in order to more accurately adjust the position of the product to be pressed before pressing, so that the product to be pressed is aligned with the center of the end product, a horizontal adjustment device 134 and a vertical adjustment device 135 can be simultaneously provided in the support device 130, and an inclined slider assembly 13522 is used in the vertical adjustment device 135. Figure 6The first fine-tuning driving member 1342 can be used to drive the connecting plate 132 to move in the horizontal direction, thereby adjusting the position of the supporting assembly 131 in the horizontal direction. At the same time, the second fine-tuning driving member 13521 can be used to drive the tilting slider assembly 13522 to move, converting the horizontal movement into the vertical movement, so as to control the vertical movement of the connecting plate 132, thereby driving the supporting assembly 131 to move in the vertical direction.

[0051] Furthermore, in order to reduce the loss of precision adjustment of the product to be pressed in the vertical direction, the vertical adjustment device 135 can be directly arranged at the bottom of the support assembly 131. Figure 7 At this time, the bottom plate 13523 is connected to the bottom of the mounting base plate 1312 through the guide column 13524, and the vertical slider 135224 is fixedly arranged at the bottom of the mounting base plate 1312. When the horizontal adjustment device 134 adjusts the horizontal position of the product to be pressed, it will simultaneously control the support assembly 131 and the vertical adjustment device 135 to move in the horizontal direction. The vertical adjustment device 135 can directly control the support assembly 131 to move in the vertical direction, so that the vertical position of the product to be pressed can be directly adjusted to ensure the adjustment accuracy.

[0052] In some embodiments, to prevent the product from being damaged due to excessive pressing pressure during the pressing process, an alarm device (not shown) may be provided in the pressing system 100. When the pressing pressure reaches or exceeds a preset pressure value, the alarm device will sound an alarm to alert the operator.

[0053] In a specific implementation scenario, the press-fitting system 100 is used in the field of the electric power industry, for example, to press-fit the flange to the end of the insulating tube to prepare an insulator product. The flange is the end product, and the insulating tube is the product to be press-fitted. Two sets of supporting devices 130 are provided in the press-fitting system 100, and both sets of supporting devices 130 are provided with horizontal adjustment devices 134 and vertical adjustment devices 135. Therefore, before press-fitting, the two flanges are placed on the two sets of press-fitting devices 120 respectively, and the insulating tube is placed on the two sets of supporting devices 130.

[0054] The detection device 140 is used to detect whether the two ends of the insulating tubes placed on the two groups of supporting devices 130 are aligned with the flanges on the same side thereof in the horizontal direction and the vertical direction. If they are not aligned in the horizontal direction, the horizontal adjustment device 134 is used to adjust the position of the insulating tube in the horizontal direction; if they are not aligned in the vertical direction, the vertical adjustment device 135 is used to adjust the position of the insulating tube in the vertical direction; if they are not aligned in both the horizontal and vertical directions, the horizontal adjustment device 134 and the vertical adjustment device 135 are used to adjust the position of the insulating tube in the horizontal and vertical directions at the same time. It can be understood that the position adjustment of the products to be pressed by each group of supporting devices 130 does not affect each other.

[0055] After the adjustment is completed, both ends of the insulating tube are aligned with the flanges on the same side thereof, and the insulating tube is fixed to the supporting device 130 by a clamping device, and at the same time, the two sets of pressing devices 120 are driven toward each other to press the flanges onto the ends of the insulating tube to complete the pressing to form an insulator product.

[0056] See also Figure 8 , Figure 8 This is a flow chart of an embodiment of the press-fitting method of the present application. Specifically, it may include the following steps:

[0057] Step S810: placing the end product on the pressing device 120 , placing the product to be pressed on at least one set of supporting devices 130 , and using the detecting device 140 to detect the position error between the product to be pressed on the supporting device 130 and the end product on the pressing device 120 .

[0058] In some embodiments, the present pressing method can be applied to the above-mentioned pressing system 100, and sensors are provided on the two groups of pressing devices 120 and at least one group of supporting devices 130 in the pressing system 100, for detecting whether end products are placed on the pressing devices 120 and whether products to be pressed are placed on the supporting devices 130.

[0059] In this step, the end product is placed on the pressing device 120 , which specifically includes step S811: placing the end product on the pressing device 120 manually or by a robot, and adjusting the end product to the center position of the pressing device 120 by using a centering adjustment component 121 .

[0060] In this step, the product to be pressed is placed on at least one group of supporting devices 130, specifically including step S812: using manual or robotic arms to place the product to be pressed on the V-shaped supporting frame of the supporting device 130, and using the V-shaped clamping device of the supporting device 130 to clamp and fix the product to be pressed.

[0061] In this step, after the end product is placed on the press-fitting device 120 and the product to be press-fitted is placed on the supporting device 130, step S813 is also included: using a sensor to detect whether the end product is placed on the press-fitting device 120 and whether the product to be press-fitted is placed on the supporting device 130. When the sensor detects that the end product is placed on the press-fitting device 120 and the product to be press-fitted is placed on the supporting device 130, a press-fitting signal is generated and sent to the press-fitting system 100 to perform subsequent steps, that is, after receiving the press-fitting signal, the press-fitting system 100 first controls the detection device 140 to detect the position error between at least one group of products to be press-fitted on the supporting device 130 and the end product on the press-fitting device 120.

[0062] In other embodiments, after placing the end product on the pressing device 120 and placing the product to be pressed on the supporting device 130, step S814 is also included: the operator presses the start button to generate a pressing signal, and sends it to the pressing system 100 to execute subsequent steps, that is, the pressing system 100 starts to use the detection device 140 to detect the position error between at least one group of products to be pressed on the supporting device 130 and the end product on the pressing device 120.

[0063] In this step, using the detection device 140 to detect the position error between the product to be pressed and the end product specifically includes step S815: taking the center of the end product as the reference point, using the detection device 140 to detect the horizontal error and height error between the center line of the product to be pressed and the reference point.

[0064] In addition, before step S810, step S840 may be included: acquiring data information of the product to be press-fitted and sending it to the press-fitting system 100, and controlling the supporting device 130 to adjust to a supporting height suitable for the product to be press-fitted.

[0065] Specifically, when it is necessary to switch the product to be pressed, the data information of the product to be pressed can be obtained by scanning the QR code on the product to be pressed, such as length information, diameter information, hardness information, etc. After receiving the data information of the product to be pressed, the pressing system 100 can first control the support device 130 to adjust to a support height suitable for the product to be pressed. In addition, the pressing system 100 can also be provided with a memory function. After the first adjustment of a product to be pressed of a certain specification, the adjustment data will be recorded and saved, and the subsequent products to be pressed of the same specification can be automatically adjusted.

[0066] Step S820: Based on the detection result of the detection device 140, control at least one adjustment device of at least one group of support devices 130 to adjust the position of the product to be press-fitted.

[0067] In some embodiments, at least one group of support devices 130 includes a connecting plate 132, at least one adjustment device includes a horizontal adjustment device 134 corresponding to the horizontal direction and a vertical adjustment device 135 corresponding to the vertical direction, the horizontal adjustment device 134 includes a first fine-tuning drive member 1342 and a first guide rail 1344, and the vertical adjustment device 135 includes a drive assembly 13513 and a lifting screw rod 13511. According to the detection result of the detection device 140, the specific steps of adjusting the position of the product to be pressed to align it with the end product are as follows:

[0068] Step S821: Based on the horizontal error detected by the detection device 140, the horizontal position of the product to be press-fitted is adjusted by using the horizontal adjustment device 134 so that the product to be press-fitted is aligned with the end product in the horizontal direction.

[0069] In this step, the horizontal position of the product to be pressed is adjusted by the horizontal adjustment device 134, specifically including step S8211: controlling the first fine-tuning drive 1342 to drive the connecting plate 132 to move along the first guide rail 1344, driving the support assembly 131 and the product to be pressed to move in the horizontal direction, so that the product to be pressed is aligned with the end product in the horizontal direction.

[0070] Specifically, in some embodiments, when the detection device 140 detects a horizontal error between the product to be pressed and the end product, the first fine-adjustment drive member 1342 can be controlled to drive, output power to the transmission assembly 1343, and transmit the power to the screw rod 13434 and the screw nut 13435 through the first bevel gear 13431 and the second bevel gear 13433 in the transmission assembly 1343, so that the screw nut 13435 rotates and moves on the screw rod 13434. Since the connecting plate 132 is fixedly connected to the screw nut 13435, when the screw nut 13435 moves, the connecting plate 132 will also move. The setting direction of the first guide rail 1344 is the same as that of the screw rod 13434, and the connecting plate 132 is connected to the first guide rail 1344 through the slider 1345. Therefore, the connecting plate 132 moves in the horizontal direction along the first guide rail 1344 driven by the screw rod nut 13435, thereby driving the supporting assembly 131 connected to the connecting plate 132 to move in the horizontal direction, so that the product to be pressed and the end product are aligned in the horizontal direction.

[0071] Step S822: Based on the height error detected by the detection device 140, the vertical adjustment device 135 is used to adjust the height position of the product to be press-fitted so that the product to be press-fitted is aligned with the end product in the vertical direction.

[0072] In this step, in some embodiments, adjusting the height position of the product to be pressed using the vertical adjustment device 135 specifically includes step S8221: controlling the drive assembly 13513 to drive the lifting screw 13511 to move up and down, driving the support assembly 131 and the product to be pressed to move in the vertical direction, so that the product to be pressed is aligned with the end product in the vertical direction.

[0073] Specifically, when the detection device 140 detects the height error between the product to be pressed and the end product, the drive component 13513 in the vertical adjustment device 135 can be controlled to output power to drive the worm lifting component 13512 to operate, so as to control the lifting and lowering of the jacking screw 13511, and adjust the height of the support component 131 connected to the jacking screw 13511, so that the product to be pressed and the end product are aligned in the vertical direction.

[0074] In this step, in some other embodiments, adjusting the height position of the product to be pressed using the vertical adjustment device 135 specifically includes step S8222: controlling the second fine-tuning drive 13521 to push the horizontal slider 135222 to move in the horizontal direction, driving the vertical slider 135224 and the connecting plate 132 to move in the vertical direction, so as to adjust the height of the support assembly 131 and the product to be pressed, so that the product to be pressed is aligned with the end product in the vertical direction.

[0075] Specifically, the vertical adjustment device 135 includes a second fine-adjustment driving member 13521, an inclined slider assembly 13522 and a bottom plate 13523. When the detection device 140 detects that there is a height error between the product to be pressed and the end product, the second fine-adjustment driving member 13521 is controlled to push the horizontal slider 135222 to move on the second guide rail 135221. When the horizontal slider 135222 moves, the inclined guide rail 135223 provided on the side thereof drives the vertical slider 135224 to move up and down, so as to convert the horizontal movement into the vertical movement, thereby controlling the connection plate 132 connected to the vertical slider 135224 to move in the vertical direction, so as to adjust the height of the support assembly 131 on the connection plate 132, so that the product to be pressed and the end product are aligned in the vertical direction.

[0076] In one implementation scenario, the above step S821 and step S822 may be performed in a sequential order, for example, step S821 is performed first, and then step S822; or, step S822 is performed first, and then step S821. In another implementation scenario, the above step S821 and step S822 may also be performed simultaneously, which may be set according to actual applications and is not limited here.

[0077] It can be understood that, only when the detection device 140 detects that there are both horizontal errors and height errors between at least one group of products to be pressed on the support device 130 and the end products on the pressing device 120, it is necessary to use the horizontal adjustment device 134 and the vertical adjustment device 135 to adjust the support assembly 131 at the same time; if the detection device 140 detects that there is an error in only one direction between the product to be pressed and the end product, it is only necessary to use the adjustment device in the corresponding direction for adjustment.

[0078] In some embodiments, the operator can input the diameter information of the product to be pressed into the HMI interface (Human Machine Interface) of the pressing system 100, and the pressing system 100 can run automatically. The detection device 140 is used to detect the error between the product to be pressed and the end product in real time, and the monitoring data is sent to the input interface of the PLC (Programmable Logic Controller) inside the pressing system 100. The PLC drives the first fine-tuning drive 1342 and the second fine-tuning drive 13521 to work according to the internal calculation, or controls the first fine-tuning drive 1342 and the second fine-tuning drive 13521 to stop working, so as to realize closed-loop control. This pressing system 100 can quickly change the type and adjust the different types of products to be pressed, which is convenient, intelligent and fast.

[0079] Step S830: Control the press-fitting device 120 to move toward the adjusted product to be press-fitted, so as to press-fit the end product to the end of the product to be press-fitted.

[0080] After the adjustment of the support device 130 is completed, the press-fitting can be started. In this step, in some embodiments, the specific process of the press-fitting may include step S831: controlling the two groups of press-fitting devices 120 to move toward each other, so as to press-fit the end products on each group of press-fitting devices 120 to the corresponding ends of the products to be press-fitted, so as to complete the press-fitting.

[0081] In this step, in some other embodiments, the specific process of pressing may include step S832: first control one group of pressing devices 120 to move toward the adjusted product to be pressed, so as to press one of the end products onto one end of the product to be pressed, and then control another group of pressing devices 120 to move toward the product to be pressed with one end product, so as to press the other end product onto the other end of the product to be pressed, so as to complete the pressing.

[0082] The horizontal adjustment device 134 and the vertical adjustment device 135 in the support device 130 of the present application can realize fast and automatic adjustment of products with different outer diameters, solve the problem of the accuracy of concentric adjustment between the product to be pressed and the pressed product during the production process, improve the pressing quality of the product, and no manual operation is required.
