Description
Technical Field
[0001] This application relates to the technical field of gear assembly equipment, and in particular to a gear pressing equipment. Background Art
[0002] A gear pressing equipment is a device used to press a bushing into the central hole of a gear to achieve the assembly of the bushing on the gear. Specifically, a gear pressing equipment usually includes a positioning device and a pressing head. The positioning device is used to position the gear at a preset position. The bushing is arranged on the pressing head, and the bushing is coaxially arranged with the central hole of the gear. When the pressing head drives the bushing to move towards the direction close to the central hole of the gear, the purpose of pressing the bushing into the central hole of the gear can be achieved.
[0003] However, in actual operation, due to various reasons, the position of the gear on the positioning device often deviates from the preset position. When the position of the gear on the positioning device deviates from the preset position, the bushing and the central hole of the gear will not be coaxial. In other words, the bushing and the central hole of the gear are not aligned. In the case where the bushing and the central hole of the gear are not aligned, forcibly pressing the bushing into the central hole of the gear through the pressing head will cause damage to the bushing or the gear, affecting the assembly accuracy of the bushing on the gear. Summary of the Utility Model
[0004] This application discloses a gear pressing equipment, which can avoid the occurrence of damage to the bushing or the gear, and make the assembly accuracy of the bushing on the gear higher.
[0005] To achieve the above object, this application discloses a gear pressing equipment, including:
[0006] A positioning device, the positioning device includes a positioning platform, a abutting mechanism and a pushing mechanism. The positioning platform is used to place the workpiece to be positioned. The abutting mechanism is arranged on the positioning platform. The abutting mechanism includes a V-shaped positioning block. The pushing mechanism includes a moving component and a pushing component. The pushing component includes a pushing piece. The pushing piece and the V-shaped positioning block are spaced opposite to each other in a first direction. The workpiece to be positioned is located between the pushing piece and the V-shaped positioning block, and the opening of the V-shaped positioning block faces the peripheral wall of the workpiece to be positioned. The pushing piece is floatingly connected to the moving component. The moving component is used to drive the pushing piece to move in the direction close to the V-shaped positioning block, and push the workpiece to be positioned into the opening of the V-shaped positioning block, so that the peripheral wall of the workpiece to be positioned abuts against the V-shaped positioning block;
[0007] A pressing head mechanism, the pressing head mechanism includes a pressing head, and the pressing head is used to press the workpiece to be pressed onto the workpiece to be positioned.
[0008] Optionally, the V-shaped positioning block is reciprocally adjustable along the first direction on the positioning platform.
[0009] Optionally, the abutting mechanism further comprises:
[0010] Abutment driving member, wherein the abutment driving member is arranged on the positioning platform and connected to the profile positioning block, and the abutment driving member is used for driving the profile positioning block to reciprocate along the first direction.
[0011] Optionally, a limiting member is provided on the positioning platform, and the limiting member is located between the profile positioning block and the positioning platform along the first direction and on a moving path of the profile positioning block.
[0012] Optionally, the limiting member is reciprocally adjustable on the positioning platform along the first direction.
[0013] Optionally, the pushing component further includes:
[0014] The mounting member is arranged on the moving assembly, and the pushing member is floatingly connected to the mounting member and is located on a side of the mounting member close to the positioning block.
[0015] Optionally, the pushing member is floatingly connected to the mounting member via an elastic member.
[0016] Optionally, the pushing component further includes:
[0017] A guide member is provided on the mounting member so as to be reciprocatingly slidable along the first direction, and the pushing member is provided on the guide member.
[0018] Optionally, the guide member is a guide rod, which is reciprocatingly slidable along the first direction and penetrates the mounting member, the pushing member is arranged at the first end of the guide rod, and the second end of the guide rod is limited to a side of the mounting member away from the pushing member.
[0019] Optionally, the gear press-fitting equipment further comprises:
[0020] A flipping mechanism, wherein the flipping mechanism is arranged on the moving component, the pushing component is arranged on the flipping mechanism, and the flipping mechanism is used to drive the part to be positioned to flip.
[0021] Compared with the prior art, the beneficial effects of this application are:
[0022] In this application, when it is necessary to position the part to be positioned, first, the part to be positioned can be placed on the positioning platform, and the part to be positioned is located between the pushing member and the type positioning block along the first direction. Then, since the pushing member is floatingly connected to the moving component, the moving component can drive the pushing member to move in the direction close to the type positioning block. During the process of the pushing member moving in the direction close to the type positioning block, the part to be positioned can be pushed into the opening of the type positioning block, and the peripheral wall of the part to be positioned abuts against the type positioning block. When the peripheral wall of the part to be positioned abuts against the type positioning block, under the guiding action of the type positioning block and the pushing action of the pushing member, the purpose of positioning the part to be positioned at the preset position can be achieved. Based on this, when this positioning device is applied to a gear pressing device and the above-mentioned part to be positioned is a gear, obviously, the purpose of positioning the gear at the preset position can be achieved through this positioning device.
[0023] After positioning the gear at the preset position, theoretically, the central hole of the gear and the bushing on the pressing head provided in the gear pressing device can be coaxial at this time. At this time, the bushing can be perfectly pressed into the central hole of the gear through the pressing head. However, during actual operation, due to various reasons, when the part to be positioned is pushed into the opening of the type positioning block and abuts against the type positioning block by the pushing member, the part to be positioned is more or less slightly deviated from the preset position. When the part to be positioned deviates from the preset position, it will cause the bushing and the central hole of the gear to be non-coaxial. In other words, the bushing and the central hole of the gear are misaligned. In the case where the bushing and the central hole of the gear are misaligned, forcibly pressing the bushing into the central hole of the gear through the pressing head will cause the bushing or the gear to be damaged, affecting the assembly accuracy of the bushing on the gear.
[0024] In this positioning device, since the pushing member is floatingly connected to the moving component, the pushing member will not fix the gear rigidly, but can make some position changes when the gear is subjected to external forces. Based on this, even if the gear deviates from the preset position due to various reasons, during the process of the pressing head pressing the bushing into the central hole of the gear, under the guiding force of the bushing, the gear can push the pushing member to make some slight position changes until the gear moves to the preset position. In this way, the bushing and the central hole of the gear can be coaxial, so that the pressing head can perfectly press the bushing into the central hole of the gear, and further, the situation of the bushing or the gear being damaged can be avoided, making the assembly accuracy of the bushing on the gear higher.

[0043] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, the meaning of "a plurality" is two or more.
[0044] The technical solution of this application will be further described below in conjunction with specific embodiments and the drawings.
[0045] This application provides a positioning device 100. Refer to Figure 1 、 Figure 2 and Figure 3 , Figure 1 is a schematic structural diagram of a positioning device 100 provided by an embodiment of this application, Figure 2 is Figure 1 a schematic structural diagram of the positioning platform 1 and the abutting mechanism 2 in Figure 3 is Figure 1 a schematic structural diagram of the pushing component 32 in Figure 1 and Figure 2 ,the abutting mechanism 2 includes a V-shaped positioning block 21. Refer toFigure 1 and Figure 3 , the pushing mechanism 3 includes a moving component 31 and a pushing component 32. The pushing component 32 includes a pushing member 321. The pushing member 321 and the V-shaped positioning block 21 are spaced opposite to each other along the first direction ( Figure 1 the X-axis direction in Figure 1 ). The piece to be positioned A is located between the pushing member 321 and the V-shaped positioning block 21, and the opening of the V-shaped positioning block 21 faces the peripheral wall of the piece to be positioned A. The pushing member 321 is floatingly connected to the moving component 31. The moving component 31 is configured to drive the pushing member 321 to move along the direction approaching the V-shaped positioning block 21 (
[0046] the negative X-axis direction in
[0047] ), move the piece to be positioned A into the opening of the V-shaped positioning block 21, so that the peripheral wall of the piece to be positioned A abuts against the V-shaped positioning block 21.
[0048] In this embodiment, when the piece to be positioned A needs to be positioned, first, the piece to be positioned A can be placed on the positioning platform 1, and the piece to be positioned A is located between the pushing member 321 and the V-shaped positioning block 21 along the first direction. Then, since the pushing member 321 is floatingly connected to the moving component 31, the moving component 31 can drive the pushing member 321 to move along the direction approaching the V-shaped positioning block 21. During the process of the pushing member 321 moving along the direction approaching the V-shaped positioning block 21, the piece to be positioned A can be pushed into the opening of the V-shaped positioning block 21, and the peripheral wall of the piece to be positioned A can be made to abut against the V-shaped positioning block 21.
[0049] In the positioning device 100, since the pushing member 321 is floatingly connected to the moving assembly 31, the pushing member 321 does not fix the gear rigidly. Instead, when the gear is subjected to an external force, it can make some positional changes. Based on this, even if the gear deviates from the preset position due to various reasons, during the process of pressing the bushing into the central hole of the gear by the pressing head, under the guiding force of the bushing, the gear can push the pushing member 321 to make some positional changes slightly until the gear moves to the preset position. In this way, the bushing can be coaxial with the central hole of the gear, so that the pressing head can perfectly press the bushing into the central hole of the gear, thereby avoiding the situation of damage to the bushing or the gear, and making the assembly accuracy of the bushing on the gear higher.
[0050] In addition, since the opening of the V-shaped positioning block 21 has the characteristics of being large at the head and small at the bottom, during the process of the pushing member 321 pushing the workpiece A to be positioned into the opening of the V-shaped positioning block 21 along the direction close to the V-shaped positioning block 21, the V-shaped positioning block 21 can well guide the workpiece A to enter the opening. After the workpiece A enters the opening, the V-shaped positioning block 21 can form a semi-wrapping state for the workpiece A, making the positioning of the V-shaped positioning block 21 for the workpiece A more accurate.
[0051] It should be noted that the understanding that the workpiece A to be positioned is a gear is only a possible understanding of the workpiece A in this embodiment based on a specific application scenario. Of course, in other application scenarios, the workpiece A to be positioned can also be other possible components, and this embodiment does not limit this.
[0052] In addition, the application of the positioning device 100 to the gear pressing device 1000 is only a possible application scenario of the positioning device 100 given in this embodiment. Of course, the positioning device 100 can also be applied to other possible scenarios, and this embodiment does not limit this.
[0053] The above-mentioned moving assembly 31 can be a linear moving platform or any structure that can drive the pushing member 321 to move along the direction close to the V-shaped positioning block 21 ( Figure 1 the negative X-axis direction in the figure), and this embodiment does not limit the moving assembly 31.
[0054] It should also be noted that the above-mentioned V-shaped positioning block 21 refers to a positioning block whose shape is approximately V-shaped. In other words, as long as the shape of the positioning block is approximately or similar to a V-shaped block, it can be regarded as the V-shaped positioning block 21, and this embodiment does not limit it in a narrow sense.
[0055] When the size of the piece to be positioned A changes, taking the piece to be positioned A as a gear as an example, when the circumferential walls of gears of different sizes abut against the V-shaped positioning block 21, the positions of the central holes of different gears relative to the V-shaped positioning block 21 are different. This will result in that when the circumferential wall of a gear abuts against the V-shaped positioning block 21, when the central hole of one type of gear can just be coaxial with the bushing, the central hole of another type of gear will not be able to be coaxial with the bushing. That is to say, this positioning device 100 is only applicable to a specific type of gear. When the type of the gear changes, it will cause this positioning device 100 to be inapplicable, and the applicable range of the positioning device 100 is relatively narrow.
[0056] In order to expand the applicable range of the positioning device 100, in some embodiments, referring to Figure 1 and Figure 2 , the V-shaped positioning block 21 is reciprocally adjustable along a first direction and is arranged on the positioning platform 1. With such an arrangement, taking the piece to be positioned A as a gear as an example, when the type of the gear becomes larger, the V-shaped positioning block 21 can move away from the pushing member 321 along the first direction, and when the type of the gear becomes smaller, the V-shaped positioning block 21 can move towards the pushing member 321 along the first direction. In this way, no matter whether the type of the gear becomes larger or smaller, the position of the central hole of the gear can remain unchanged.
[0057] It can be seen that by making the V-shaped positioning block 21 reciprocally adjustable along the first direction and arranged on the positioning platform 1, the positioning device 100 can be applicable to different types of pieces to be positioned A, and the applicable range is wider.
[0058] In some embodiments, referring to Figure 2 and Figure 4 , Figure 4 is Figure 1 a top view of the abutting mechanism 2 in
[0059] The abutting mechanism 2 further includes: an abutting driving member 22, the abutting driving member 22 is arranged on the positioning platform 1 and is connected to the V-shaped positioning block 21, and the abutting driving member 22 is used to drive the V-shaped positioning block 21 to reciprocally adjust along the first direction.
[0060] By arranging the abutting driving member 22, when it is necessary to reciprocally adjust the position of the V-shaped positioning block 21 along the first direction, it can be realized by driving the V-shaped positioning block 21 to move through the abutting driving member 22, and the degree of automation is higher.
[0061] Among them, the above-mentioned abutting driving member 22 can be a cylinder, an electric cylinder or a motor, etc., and this embodiment does not make any limitation thereto.
[0062] In order to ensure the adjustment accuracy when the abutting driving member 22 drives the V-shaped positioning block 21 to reciprocally adjust in the first direction, in some embodiments, refer to Figure 2 and Figure 4 , a limiting member 23 is provided on the positioning platform 1. The limiting member 23 is located between the V-shaped positioning block 21 and the positioning platform 1 in the first direction ( Figure 4 the X-axis direction in
[0063] ) and is located on the moving path of the V-shaped positioning block 21.
[0064] Since the limiting member 23 is located between the V-shaped positioning block 21 and the positioning platform 1 in the first direction and is located on the moving path of the V-shaped positioning block 21, therefore, in the process of the abutting driving member 22 driving the V-shaped positioning block 21 to move towards the positioning platform 1 in the first direction, when the V-shaped positioning block 21 moves to the limiting member 23, the limiting member 23 will prevent the V-shaped positioning block 21 from continuing to move towards the positioning platform 1 in the first direction. In this way, under the limiting action of the limiting member 23, the V-shaped positioning block 21 can accurately stop at the limiting member 23, and it can avoid the problem of poor adjustment accuracy when the V-shaped positioning block 21 reciprocally adjusts in the first direction due to the poor driving accuracy of the abutting driving member 22. Figure 4 , the limiting member 23 is reciprocally adjustable along the first direction and is provided on the positioning platform 1.
[0065] By reciprocally adjusting the limiting member 23 along the first direction and setting it on the positioning platform 1, when it is necessary to limit the V-shaped positioning block 21 to different positions, it can be achieved only by reciprocally adjusting the limiting member 23 along the first direction, so that the V-shaped positioning block 21 can be limited to different positions as needed, which is very flexible.
[0066] Among them, the above-mentioned limiting member 23 can be a screw. When the limiting member 23 is a screw, the screw can be threadedly connected to the positioning platform 1 and the axial direction of the screw extends along the first direction. In this way, by screwing the screw, the purpose of reciprocally adjusting the limiting member 23 along the first direction can be achieved. The implementation method is very simple, and since the cost of the screw is also relatively low, the cost of the limiting member 23 can be reduced.
[0067] Of course, the limiting member 23 can also be other possible devices, and this embodiment does not limit this.
[0068] In some embodiments, refer to Figure 1 , Figure 3 and Figure 5 , Figure 5 is Figure 3The top view of the pushing component 32 in [it], the pushing component 32 further includes: a mounting member 322, the mounting member 322 is arranged on the moving component 31, and the pushing member 321 is floatingly connected to the mounting member 322 and is located on the side of the mounting member 322 close to the V-shaped positioning block 21.
[0069] Since the mounting member 322 is arranged on the moving component 31, and the pushing member 321 is floatingly connected to the mounting member 322 and is located on the side of the mounting member 322 close to the V-shaped positioning block 21, therefore, when the moving component 31 drives the mounting member 322 to move in the direction close to the V-shaped positioning block 21, the purpose of synchronously driving the pushing member 321 to move in the direction close to the V-shaped positioning block 21 can be achieved.
[0070] By arranging the mounting member 322, when the purpose of floatingly connecting the pushing member 321 to the moving component 31 needs to be achieved, only by making the pushing member 321 floatingly connected to the mounting member 322 to form a module, and then installing the mounting member 322 on the moving component 31 can the purpose of floatingly connecting the pushing member 321 to the moving component 31 be achieved. Compared with the method of directly floatingly connecting the pushing member 321 to the moving component 31, the difficulty of floatingly connecting the pushing member 321 to the moving component 31 can be reduced.
[0071] Wherein, the above-mentioned mounting member 322 can be in a plate-like structure, a disc-like structure or a frame structure, etc., and this embodiment does not limit this.
[0072] It should be noted that there are various ways to realize the floating connection of the pushing member 321 to the mounting member 322. For example, in one possible implementation, the pushing member 321 is floatingly connected to the mounting member 322 through a motor. Specifically, the fixed end of the motor can be fixed to the mounting member 322, and the telescopic end can be connected to the pushing member 321. When the pushing member 321 receives a pressing force from the to-be-positioned member A in the first direction towards the mounting member 322 and the pressing force is greater than a preset value, the motor can drive the pushing member 321 to move in the first direction towards the mounting member 322. In this way, the purpose of making the pushing member 321 floatingly connected to the mounting member 322 can be achieved.
[0073] Of course, the purpose of making the pushing member 321 floatingly connected to the mounting member 322 can also be achieved by other means. For example, in another possible implementation, see Figure 3 and Figure 5 , the pushing member 321 is floatingly connected to the mounting member 322 through an elastic member 324.
[0074] Since the elastic member 324 has an elastic function, when the pushing member 321 is subjected to a pressure from the to-be-positioned member A along the first direction toward the mounting member 322, the pushing member 321 can move along the first direction toward the mounting member 322 and the elastic member 324 can be compressed. When the pressure exerted on the pushing member 321 disappears, the elastic member 324 can restore its original shape and drive the pushing member 321 to move along the first direction away from the mounting member 322. At this point, the purpose of floatingly connecting the pushing member 321 to the mounting member 322 through the elastic member 324 is achieved.
[0075] Since the elastic member 324 has the advantages of simple structure and low cost, when the pushing member 321 is floatingly connected to the mounting member 322 through the elastic member 324, the structure of the positioning device 100 can be simplified to a certain extent, and the cost of the positioning device 100 can be reduced.
[0076] Of course, the pushing member 321 may also be connected to the mounting member 322 in a floating manner through other methods, which will not be listed one by one in this embodiment.
[0077] In order to make the pusher 321 reciprocate more steadily and smoothly along the first direction, in some embodiments, see Figure 4 and Figure 5 The pushing component 32 further includes: a guide member 323 , which is reciprocatingly slidably disposed on the mounting member 322 along a first direction, and the pushing member 321 is disposed on the guide member 323 .
[0078] Since the pushing member 321 is arranged on the guide member 323, and the guide member 323 is arranged on the mounting member 322 so as to be reciprocatingly slidable along the first direction, the pushing member 321 can be guided by the guide member 323 to slide reciprocatingly along the first direction more stably and smoothly.
[0079] There are many implementations of the guide member 323. In one possible implementation, the guide member 323 may be a guide plate, which is reciprocally slidably disposed on the mounting member 322 along a first direction through a slide rail assembly. In another possible implementation, see Figure 4 and Figure 5 The guide member 323 is a guide rod, which is reciprocatingly slidably disposed in the mounting member 322 along a first direction. The pushing member 321 is disposed at a first end of the guide rod, and a second end of the guide rod is limited to a side of the mounting member 322 away from the pushing member 321.
[0080] When the guide member 323 is a guide rod, the purpose of making the guide rod slidably reciprocatingly arranged on the mounting member 322 along the first direction can be achieved by allowing the guide rod to pass through the mounting member 322 so as to be reciprocatingly slidable along the first direction. When the guide rod passes through the mounting member 322, the mounting member 322 can surround the peripheral wall of the guide rod to protect the guide rod, so that the guide rod is more securely connected to the mounting member 322 so as to be reciprocatingly slidable along the first direction.
[0081] Since the pushing member 321 is disposed at the first end of the guide rod and the second end of the guide rod is limited to the side of the mounting member 322 away from the pushing member 321 , the guide rod can be prevented from sliding out of the mounting member 322 .
[0082] The guide rod can be reciprocatingly slidably disposed in the mounting member 322 via a linear bearing along the first direction. With this arrangement, the guide rod can be more stable and smooth when reciprocatingly slidably disposed in the first direction under the guiding action of the linear bearing.
[0083] In some embodiments, see Figure 5 The elastic member 324 is a spring, which is sleeved on the guide rod and located between the pushing member 321 and the mounting member 322 .
[0084] Since the spring is sleeved on the guide rod and is located between the pushing member 321 and the mounting member 322, the guide rod can support the spring, thereby preventing the spring from tilting during the compression process, making the spring run more reliably.
[0085] Of course, the elastic member 324 being a spring is only one possible implementation method given in this embodiment. In another possible implementation method, the elastic member 324 may also be a spring or any other possible elastic element, which is not limited in this embodiment.
[0086] In some embodiments, see Figure 1 The positioning device 100 further includes: a flipping mechanism 4, which is disposed on the moving component 31, and a pushing component 32 is disposed on the flipping mechanism 4, and the flipping mechanism 4 is used to drive the part A to be positioned to flip.
[0087] By setting up the flipping mechanism 4, continuing to take the positioning device 100 applied to the gear pressing equipment 1000 and the part A to be positioned as a gear as an example, after the bushing is pressed into the center hole of the gear, the gear can be flipped 180° by the flipping mechanism 4 so that the bottom surface of the gear faces upward, so as to perform other operations on the bottom surface of the gear, making the functions of the positioning device 100 more abundant and diverse.
[0088] In addition, by arranging the pushing component 32 on the flipping mechanism 4, the pushing component 32 can be directly integrated into the flipping mechanism 4. In this way, the pushing component 32 and the flipping mechanism 4 can share a moving component 31. Compared with the method of separately equipping a moving component 31 for the pushing component 32 and the flipping mechanism 4 respectively, the integration degree of the positioning device 100 can be higher and the structure can be more concise.
[0089] Among them, referring to Figure 1 , the above-mentioned flipping mechanism 4 may include a mounting frame 41 and a flipping motor 42. The mounting frame 41 is arranged on the moving component 31. The fixed end of the flipping motor 42 is fixed to the mounting frame 41, and the rotating shaft of the flipping motor 42 is connected to the pushing component 32.
[0090] Of course, the flipping mechanism 4 may also be other possible structures, and this embodiment does not limit this.
[0091] This application also provides a gear pressing device 1000. Referring to Figure 6 , Figure 6 is a schematic structural diagram of a gear pressing device 1000 provided by an embodiment of this application. The gear pressing device 1000 includes a pressing head mechanism 200 and a positioning device 100. Among them, the pressing head mechanism 200 includes a pressing head 201, and the pressing head 201 is used to press a to-be-pressed part B onto a to-be-positioned part A.
[0092] Among them, the structure of the positioning device 100 may be the same as the structure of the positioning device 100 described in any of the above embodiments, and can bring the same or similar beneficial effects. For details, reference can be made to the description of the positioning device 100 in the above embodiments, and this embodiment will not be elaborated here.
[0093] When the positioning device 100 is applied to the gear pressing device 1000, the above-mentioned to-be-pressed part B may be a bushing, and the above-mentioned to-be-positioned part A may be a gear.
[0094] In this embodiment, since the pushing member 321 of the positioning device 100 is floatingly connected to the moving component 31, when the positioning device 100 is applied to the gear pressing device 1000, the pushing member 321 does not fix the gear rigidly. Instead, when the gear is subjected to an external force, it can make some position changes. Based on this, even if the gear deviates from the preset position due to various reasons, during the process of pressing the bushing into the central hole of the gear by the pressing head, under the guiding force of the bushing, the gear can push the pushing member 321 to make some position changes slightly until the gear moves to the preset position. In this way, the bushing and the central hole of the gear can be coaxially aligned, so that the bushing can be perfectly pressed into the central hole of the gear by the pressing head, and further, the situation of damage to the bushing or the gear can be avoided, and the assembly accuracy of the bushing on the gear can be higher.
[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
