[0044] See also Figure 1 , Figure 2 and Figure 3 The first embodiment of the utility model provides a double-sided pressing device 1, which is used to press bearings 3 into both sides of a product 2 to be processed, such as a plastic product, at the same time. The device comprises an operating table 11 and a pressing assembly 12 disposed on the operating table 11. The pressing assembly 12 comprises a first pressing assembly 121, a positioning fixture 122, and a second pressing assembly 123 disposed on opposite sides of the positioning fixture 122. The first pressing assembly 121 is disposed at one end of the second pressing assembly 123 away from the operating table 11, the first pressing assembly 121 moves close to the second pressing assembly 123, and the second pressing assembly 123 moves toward the positioning fixture 122 under the push of the first pressing assembly 121.

[0045] The second pressing component 123 is arranged on the opposite sides of the positioning fixing piece 122, and the positioning fixing piece 122 is used to fix the product 2 to be processed. The first pressing component 121 moves toward the second pressing component 123, and pushes the second pressing component 123 to move from the two sides of the positioning fixing piece 122 toward the positioning fixing piece 122, so that the bearing 3 is pressed into both sides of the product 2 to be processed at the same time, which solves the technical problem that most of the existing bearing pressing equipment can only assemble on one side but not on both sides at the same time, thereby improving the production efficiency.

[0046] It should be noted that the positioning fixing member 122 should be provided with a structure for fixing the product to be processed 2 corresponding to the product to be processed 2, such as the positioning fixing member 122 is provided with a placement groove corresponding to the product to be processed 2, the product to be processed 2 is clamped and placed in the placement groove, and at the same time, the placement groove is provided with a clamping structure or a supporting structure corresponding to the product to be processed 2 to fasten the product to be processed 2 to prevent it from shaking or the like.

[0047] For further information, see Figure 1 and Figure 2The first pressing component 121 includes a main body 1211 and inclined pieces 1212 arranged at both ends of the main body 1211, and the second pressing component 123 includes two pressing pieces 1231 symmetrically arranged on the opposite sides of the positioning and fixing piece 122, and the two inclined pieces 1212 are provided with inclined surfaces 12121 on the outer sides close to the corresponding pressing pieces 1231, and / or, the pressing pieces 1231 are provided with matching inclined surfaces 12311 close to the inclined pieces 1212. When the first pressing component 121 is driven by the power component 13 to move in the direction of the second pressing component 123 and after the two are in contact, at this time, because the pressing piece 1231 is provided with a slope 12121, and / or the pressing piece 1231 is provided with a matching slope 12311 close to the inclined surface piece 1212, the pressing piece 1231 and the inclined surface piece 1212 form an inclined surface match, and the downward pressure of the first pressing component 121 is transmitted and converted into a driving force that makes the two pressing pieces 1231 move close to the positioning fixing piece 122, that is, the unidirectional downward pressure of the first pressing component 121 is converted into two bidirectional relative horizontal pressing forces, so that the bearings 3 are assembled on both sides of the product 2 to be processed at the same time.

[0048] It can be understood that the inclined surface 12121 provided on the inclined surface 12121 and the matching inclined surface 12311 provided on the pressing component 1231 do not need to be provided at the same time, and at least one of the conditions can be provided to convert the unidirectional downward force of the first pressing component 121 into two bidirectional relative pressing horizontal pressing forces, so as to realize the simultaneous assembly of the bearing 3 on both sides of the product 2 to be processed. Preferably, the two inclined surface members 1212 are provided with inclined surfaces 12121 close to the corresponding pressing components 1231, and the pressing components 1231 are provided with matching inclined surfaces 12311 corresponding to the inclined surfaces 12121. At this time, when the inclined surfaces 12121 and the matching inclined surfaces 12311 are matched with each other, the matching area between the inclined surface member 1212 and the pressing component 1231 can be increased to reduce the loss of the device.

[0049] For further information, see Figure 2 and Figure 3The second pressing assembly 123 also includes a pressing rod 1232 disposed on the side of the pressing piece 1231 close to the positioning fixing piece 122, and the pressing rod 1232 is detachably connected to the fixing piece. The pressing rod 1232 is used to carry the bearing 3 to be assembled with the product 2 to be processed. When the pressing piece 1231 drives the pressing rod 1232 to move toward the positioning fixing piece 122, that is, the product 2 to be processed, when it moves to a suitable position, the pressing rod 1232 will carry the bearing 3 near one end of the product 2 to be processed and press it into the position where the bearing 3 needs to be installed at a certain depth, that is, to achieve mechanical assembly. Compared with traditional manual assembly, it can improve work efficiency, reduce labor costs and reduce the defect rate. The pressing rod 1232 is detachably connected to the fixing piece, which is conducive to the installation of bearings 3 of different shapes and sizes required for different products. The corresponding different pressing rods 1232 can be replaced to achieve the universal effect of the device and expand the scope of use of the device.

[0050] Specifically, one end of the pressing rod 1232 is detachably connected to the fixing piece, and the other end should be provided with a structure matching the bearing 3 to carry the bearing 3, such as a protruding block 12321 that can be set on this end of the pressing rod 1232 and matches the shape and size of the inner ring of the bearing 3.

[0051] It should be supplemented that the position of the pressing rod 1232 should correspond to the position of the sleeve of the bearing 3 required to be assembled on the product 2 to be processed, and the number of pressing rods 1232 corresponding to one pressing piece 1231 is not limited, and should be less than or equal to the number of sleeves required to be assembled on this side of the product 2 to be processed. It can be understood that according to the actual needs of the product 2 to be processed, when symmetrical bearings 3 need to be assembled on both sides of the product 2 to be processed, the pressing rods 1232 on the two pressing pieces 1231 should be symmetrically arranged with respect to the positioning fixing piece 122; when asymmetric bearings 3 need to be assembled on both sides of the product 2 to be processed, the pressing rods 1232 are arranged according to the actual situation of the product 2 to be processed, that is, the pressing rods 1232 are not necessarily symmetrically arranged on the two symmetrically arranged pressing pieces 1231, so that in actual applications, a more flexible production strategy can be adopted in combination with the actual situation.

[0052] For further information, see Figure 1 , Figure 2 and Figure 3 The second pressing assembly 123 also includes a guide rail 1233 arranged on the operating table 11, the pressing piece 1231 is slidably connected to the guide rail 1233, and one end of the guide rail 1233 is arranged close to the positioning fixing piece 122, so that the pressing piece 1231 moves along the guide rail 1233 toward or away from the positioning fixing piece 122, ensuring that the trajectory of the pressing piece 1231 moving toward the positioning fixing piece 122, that is, toward the product 2 to be processed, is accurate and without deviation, thereby ensuring that the bearing 3 is accurately pressed into the corresponding position of the product 2 to be processed.

[0053] It should be noted here that the guide rails 1233 should be symmetrically arranged on both sides of the positioning fixture 122, wherein the guide rails 1233 are two guide rails 1233 with one end close to the positioning fixture 122 and corresponding to the pressing piece 1231, or a guide rail 1233 that penetrates the positioning fixture 122 and is symmetrically distributed on both sides of the positioning fixture 122. In this case, the positioning fixture 122 should be provided with an avoidance structure for the guide rail 1233 to pass through. In summary, it is preferred that the pressing piece 1231, the guide rail 1233 and the pressing rod 1232 are symmetrically distributed on both sides of the positioning fixture 122, which ensures the concentricity of the bearing 3 relative to the processed product 2, especially the symmetrical product, and the transmission efficiency and stability of the entire device, so that the bearings assembled on both sides have simultaneity and consistency of the effect after assembly.

[0054] In addition, the first pressing assembly 121 (pressing member 1231 and guide rail 1233) and positioning fixing member 122 can actually be detachably mounted on the fixed base plate 124, and the fixed base plate 124 is then detachably connected to the operating table 11, so that the needs of assembling bearings 3 for different types of workpieces to be processed can be met by simply replacing the fixed plate and positioning fixing member 122, thereby expanding the scope of application of the entire double-sided pressing device 1. Specifically, the operating table 11 is provided with a plurality of connection holes 111 of different positions, sizes, shapes, etc., which can be connected to the fixed base plate 124 or the pressing assembly 12, etc., and the fixed base plate 124 can be connected to the connection holes 111 to be fixed to the operating table 11.

[0055] For further information, see Figure 2 , Figure 3 , Figure 4 and Figure 6 The double-sided pressing device 1 also includes a power assembly 13 connected to the first pressing assembly 121. The power assembly 13 includes a power device 131, a matching piece 132, a stopper 135 and at least two guide rods 133. The matching piece 132 is arranged on one side of the main body 1211 close to the power device 131, and this side is connected to the main body 1211, and the other side is connected to the power device 131. One end of the guide rod 133 is detachably connected to the operating table 11, and is respectively arranged at both ends of the pressing assembly 12. The stopper 135 is arranged on the guide rod 133 corresponding to the matching piece 132, and the matching piece 132 is provided with a matching hole 1321 corresponding to the limiting piece 135. The matching piece 132 is sleeved on the stopper 135 through the matching hole 1321, so that the matching piece 132 moves along the guide rod 133 to the direction close to the pressing assembly 12 under the driving force of the power device 131, and pushes the first pressing assembly 121 to move close to the second pressing assembly 123.

[0056] The power device 131 is connected to the matching piece 132, so that the power device 131 drives the matching piece 132 to move, thereby pushing the first pressing assembly 121 to move close to the second pressing assembly 123, so that the pressing pieces 1231 on both sides of the positioning fixing piece 122 move toward the positioning fixing piece 122, and press the bearing 3 into the product to be processed 2. The limiting piece 135 is arranged on the guide rod 133, and the matching piece 132 has a matching hole 1321 which is sleeved on the limiting piece 135, so that the matching piece 132 can only move along the limiting piece 135, which limits its movement direction and trajectory, and ensures the straightness of the matching piece 132 moving close to or away from the first pressing assembly 121.

[0057] It should be noted here that the power device 131 can be specifically a cylinder, etc. The connection method of the fitting 132 and the main body 1211 can be that the two are detachably connected, or the two can be directly designed as an integral molding. In addition, the guide rod 133 is a straight rod-shaped object, which is arranged vertically on the operating table 11 to ensure that the power device 131, the fitting 132, etc. perform linear motion at equal times and distances at each point. The specific number is not limited under the premise of ensuring that there is at least one at each of the two opposite ends of the press-fit assembly 12, and it is preferably an even number of symmetrically designed guide rods 133, such as four guide rods 133 arranged at the four corners of the square fitting 132.

[0058] For further information, see Figure 2 , Figure 3 , Figure 4 and Figure 5 The power assembly 13 further includes a movable member 134, which is disposed between the power device 131 and the matching member 132. The movable member 134 has a movable hole 1341 corresponding to the guide rod 133. The movable member 134 is movably sleeved on one end of the guide rod 133 close to the power device 131 through the movable hole 1341, and is located at one end of the stopper 135 away from the press-fit assembly 12. The outer diameter of the stopper 135 is greater than the outer diameter of the guide rod 133.

[0059] The movable member 134 is sleeved on the guide rod 133 and located at one end of the limiter 135 close to the power assembly 13. The outer diameter of the limiter 135 is larger than the outer diameter of the guide rod 133 to limit the movable range of the movable member 134, that is, the movable member 134 can only move within the range of the guide rod 133 on the side of the limiter 135 close to the power device 131, but cannot move within the range of the limiter 135 and the guide rod 133 on the other side of the limiter 135. The movable member 134 is integrally arranged between the power device 131 and the matching member 132, thereby controlling the maximum stroke of the power assembly 13 and the matching member 132 to move toward the first pressing assembly 121, further ensuring the maximum stroke of the second pressing assembly 123, and ensuring that the depth of the bearing 3 pressed into the product meets the process requirements.

[0060] For further information, see Figure 4 and Figure 5The power assembly 13 also includes a connecting member 136, the two ends of which are respectively connected to the power device 131 and the matching member 132, and the movable member 134 is provided with a through hole 1342 corresponding to the connecting member 136, and the connecting member 136 penetrates the through hole 1342. By providing the connecting member 136, the power device 131 and the matching member 132 are connected to ensure the consistency of their movements; the movable member 134 is provided with a through hole 1342 corresponding to the connecting member 136, and the connecting member 136 penetrates the through hole 1342, so that the movable member 134 abuts against the power device 131 and is located between the power device 131 and the matching member 132, thereby realizing the control of the downward stroke of the power device 131.

[0061] For further information, see Figure 2 and Figure 4 The maximum travel of the movable member 134 along the guide rod 133 and the connecting member 136 is equal to the distance between the end of the guide rod 133 away from the pressing assembly 12 and the stopper 135, so as to limit the maximum travel of the power device 131. In addition, this distance also corresponds to the maximum travel of the pressing member 1231, ensuring that the depth of the bearing 3 pressed into the product meets the process requirements. The length of the stopper 135 along the radial direction of the guide rod 133 is greater than the travel distance of the movable member 134 along the guide rod 133, so as to ensure that the matching member 132 will not be separated from the stopper 135 when moving.

[0062] Understandably, please combine Figure 3 and Figure 5 , the cross-sectional area of ​​the through hole 1342 should not be larger than the cross-sectional area of ​​the power device 131, so that only the connecting member 136 passes through the through hole 1342, and the power device 131 and the matching member 132 are located on both sides of the movable member 134. When the power device 131 provides a driving force to drive the matching plate to move to a certain extent toward the first pressing assembly 121, the power device 131 contacts the movable member 134 and pushes the movable member 134 to move in the same direction as the guide rod 133. When the movable member 134 moves to abut the limit member 135, it stops moving. At this time, the matching member 132 pushes the pressing member 1231 to move toward the positioning fixing member 122 and stops. The pressing rod 1232 presses the bearing 3 into the product 2 to be processed to a suitable depth, completing the assembly of the bearing 3 and the product 2 to be processed. The movement accuracy of the power device 131 can reach 0.02mm, and combined with the stroke of the power device 131 moving toward the pressing assembly 12 (i.e., the downward pressing stroke), the depth of the bearing 3 is jointly guaranteed.

[0063] For further information, see Figure 1 and Figure 7The double-sided pressing device 1 also includes an electric control box 14 and a protective device 15 which are arranged on the operating table 11 and are electrically connected to the pressing assembly 12 and the power assembly 13. The electric control box 14 is arranged to automatically control the double-sided pressing device 1 to work. The protective device 15 is used to detect the surrounding environment of the double-sided pressing device 1 to ensure that the working environment is normal. When the operator is operating around, it prevents accidents and accidental injuries to the human body. If the operator's hand is on the operating table 11 at this time, the protective device 15 will not start the device to run because the hand is not in compliance with the standard through parameters such as the distance between the grating and the pressing assembly 12, so as to ensure the safe operation of the double-sided pressing device 1 and the personal safety of the operator.

[0064] It should be supplemented that the protective device 15 can be a protective grating or a sensor, etc., and its setting position can be appropriately arranged according to the specific type of product. For example, when the protective device 15 is a protective grating, it can be set at opposite ends of the operating table 11.

[0065] Please also combine Figure 2 and Figure 3 It can be understood that after power is turned on, the electrical control box 14 controls the power component 13 to provide driving force to drive the first pressing component 121 to move toward the second pressing component 123, and converts the unidirectional downward force transmission into two bidirectional relative horizontal pressing forces under the cooperation of the inclined surface 12121 and the matching inclined surface 12311, so as to push the pressing part 1231 to move toward the positioning fixing part 122, and the pressing rod 1232 presses the bearing 3 into the product to be processed 2, completing the simultaneous assembly of the bearing 3 on both sides of the product to be processed 2. After this series of processes, that is, after the operation of the entire device is completed, each component can be automatically reset under the control of the electrical control box 14 for the next operation, with a high degree of automation.

Any modifications, equivalent replacements and improvements made within the principles of the present invention should be included in the protection scope of the present invention.
