[0001] This utility model relates to the field of automotive transmission parts installation, and in particular to a multifunctional press-fitting fixture for automotive transmission parts. Background Technology

[0002] Press-fitting fixtures are specialized tools or equipment used in the assembly process of automotive transmissions to accurately and efficiently press various parts into place.

[0003] In the production process of automotive transmission parts, traditional press-fitting fixtures require multiple adjustments to the position of the transmission parts after they are placed on the placement table to center them, and then multiple bolts are used to fix and limit their position. This process involves many steps, and manual centering adjustments introduce certain errors, which affects the accuracy of press-fitting and reduces the efficiency of press-fitting. Utility Model Content

[0004] The technical problem this utility model aims to solve is that in the production process of automotive transmission parts, traditional press-fitting fixtures require multiple adjustments to the position of the transmission parts after they are placed on the placement table to center them, and then multiple bolts are used to fix and limit their position. This involves many steps, and manual centering adjustments introduce certain errors, thus affecting the accuracy of press-fitting and reducing the efficiency of press-fitting processing.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a multi-functional press-fitting fixture for automotive transmission parts, including a press-fitting machine. A cylinder is provided on the top of the press-fitting machine, and the output end of the cylinder is installed through one side of the press-fitting machine. A press-fitting plate is fixedly installed on one side of the press-fitting machine. A placement platform is provided on one side of the placement platform. A limiting centering device is provided on one side of the placement platform. The limiting centering device can drive two threaded hole limiting blocks with a threaded rod to quickly center and fix the automotive transmission on the placement platform in coordination with an adjustment mechanism, which facilitates press-fitting processing.

[0006] The aforementioned components achieve the following effects: During the press-fitting of automotive transmission parts, the assembled parts are placed on a placement table. A limiting and centering device then quickly centers the parts in the middle of the placement table and fixes them in place, facilitating subsequent press-fitting, improving efficiency and accuracy, and reducing errors caused by manual operation. During press-fitting, a cylinder can be activated to move the press plate downwards, pressing the automotive transmission parts on the placement table. It should be noted that the cylinder is a mature technology and equipment in the existing field; its internal structure, connection method, and principle will not be elaborated upon further.

[0007] Preferably, the limiting and centering device includes a groove frame, with a replacement device provided between one side of the groove frame and one side of the placement platform; a threaded rod, one end of which is installed through the inner wall of the groove frame, and the threads at both ends are in opposite directions; a servo motor, one side of which is fixedly installed on one side of the groove frame, and the output end is fixedly installed on one end of the threaded rod via a coupling; two screw hole limiting blocks, one end of which is slidably installed in the inner wall of the groove frame, and the inner wall threads are installed on the outer surface of the threaded rod; and several adjustment mechanisms, wherein the adjustment mechanisms are disposed in the inner walls at both ends of the screw hole limiting blocks, for adjusting the length of both ends of the screw hole limiting plate, thereby improving the usability of the screw hole limiting blocks.

[0008] The effect achieved by the aforementioned components is as follows: By setting up a centering and limiting device, after the assembled automotive transmission parts are placed on the placement table, the servo motor can be activated to drive the threaded rod to rotate within the inner wall of the grooved frame. This causes the two threaded hole limiting blocks and the adjustment mechanism to move in opposite directions. Since the openings of the two threaded hole limiting blocks gradually decrease towards the bottom, during the clamping process, the inner walls at both ends will press against the outer surface of the transmission parts, pushing them towards the center, thus achieving a centering effect and simultaneously limiting their movement. This allows the transmission parts placed on the placement table to be quickly centered to the center of the placement table, directly below the pressing plate, facilitating subsequent pressing processes, improving pressing efficiency and accuracy, and reducing errors caused by manual operation. It should be noted that the servo motor is a mature technology and equipment in the existing field; its internal structure, connection method, and principle will not be elaborated upon further.

[0009] Preferably, the adjustment mechanism includes an adjustment limiting block, wherein one end of the adjustment limiting block is slidably mounted in the inner wall of one end of the screw hole limiting block; and a plurality of first springs, wherein the two ends of the first springs are respectively fixedly mounted on the inner wall of the screw hole limiting block and one side of the adjustment limiting block.

[0010] The effect achieved by the above-mentioned components is as follows: By setting an adjustment mechanism, when using the screw hole limit block to limit and center the automotive transmission parts, if the size of the automotive transmission to be pressed is smaller than the inner wall size of the screw hole limit block and the adjustment limit block, when it is limited, one end of the two opposing adjustment limit blocks will abut together. As the screw hole limit block moves, they abut against each other and retract into the inner wall of the screw hole block, causing the first spring to contract. When limiting and centering automotive transmission parts with a larger inner wall size than the screw hole limit block and the adjustment limit block, the inner wall of the adjustment limit block will abut against the transmission part, pushing it to the center. Through this adjustment, the adaptability of the screw hole limit block can be improved, making it easier to center and limit transmission parts of various sizes.

[0011] Preferably, the adjustment mechanism further includes a limiting rod, wherein one end of the limiting rod is fixedly installed on one side of the inner wall of the screw hole limiting block, and the outer surface of the limiting rod passes through the inner wall of the first spring and is slidably connected to the inner wall of the adjusting limiting block.

[0012] The effect achieved by the above components is that by setting the limiting rod, the inner wall of the first spring can be supported and reinforced, while the adjusting limiting block can be limited, so that it is not easy to shake during the squeezing adjustment.

[0013] Preferably, the easy-to-replace device includes two locking blocks, one side of which is fixedly installed on the bottom side of the groove frame. A rectangular groove is provided on one side of the placement platform, and sliding holes are symmetrically provided on one side of the inner wall of the rectangular groove. The groove frame and the locking blocks are respectively inserted into the inner walls of the rectangular groove and the sliding holes; two locking blocks, one end of which is slidably installed in the inner wall of one end of the sliding hole, and the other end is inserted into the inner wall of the locking block; and several second springs, the two ends of which are respectively fixedly installed on one side of the locking block and one side of the placement platform.

[0014] The effect achieved by the above components is as follows: by setting up an easy replacement device, when it is necessary to replace and maintain the groove frame and the screw hole limit block, the locking block can be manually pulled outward in the inner wall of the sliding hole to a certain position, which will cause the second spring to be stretched open, so that one end of it is pulled out from the inner wall of the locking block. Then, the groove frame is pulled upward to pull it out of the rectangular groove, so that the locking block can be pulled out of the sliding hole, and the groove frame can be removed from the placement table for easy maintenance and replacement.

[0015] Preferably, the longitudinal section of the locking block is trapezoidal, and the dimension of the end of the locking block away from the second spring is smaller than the dimension of the other end.

[0016] The effect achieved by the above components is that by setting the locking block in a trapezoidal shape, when installing the groove bracket, it is not necessary to pull the locking block. Instead, the locking block can be manually inserted into the sliding hole to a certain position, and then it can be pushed to slide in the sliding hole, which facilitates installation.

[0017] Preferably, a plurality of circular rollers are rotatably mounted on one side of the card block, and the plurality of circular rollers are arranged at equal intervals.

[0018] The effect achieved by the above components is that by setting the roller, the contact friction between one side of the locking block and one side of the locking hole block can be reduced, making it easier to push the locking hole block when one side of the locking hole block is pressed against the other side of the locking block.

[0019] Preferably, a pull block is fixedly installed on one side of the card block, and the cross-section of the pull block is arc-shaped.

[0020] The effect achieved by the above components is that by setting up the pull block, the contact area on one side of the block can be increased, making it easier to manually hold and pull it, and facilitating disassembly and replacement later.

[0021] The beneficial effects of this utility model are:

[0022] By setting a centering and limiting device, after the assembled automotive transmission parts are placed on the placement table, the servo motor can be started to drive the threaded rod to rotate in the inner wall of the groove frame. This causes the two threaded hole limiting blocks and the adjustment mechanism to move in opposite directions. Since the openings of the two threaded hole limiting blocks gradually decrease towards the bottom, during the clamping process, the inner walls at both ends will squeeze the outer surface of the transmission parts and push them towards the center, thus achieving a centering effect and limiting their movement. This allows the transmission parts placed on the placement table to be quickly centered to the center of the placement table, directly below the pressing plate, which facilitates subsequent pressing processing, improves pressing efficiency and accuracy, and reduces errors caused by manual operation.

These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Figure 1-5 The multi-functional press-fitting fixture for automotive transmission parts shown includes a press-fitting machine 1. A cylinder 5 is mounted on the top of the press-fitting machine 1, with its output end installed through one side of the machine. A press-fitting plate 6 is fixedly mounted on one side of the press-fitting machine 1. A placement table 4 is located on one side of the placement table 4, and a limiting centering device 2 is installed on one side of the placement table 4. The limiting centering device 2, through a threaded rod 22, drives two threaded hole limiting blocks 24 in conjunction with an adjusting mechanism 25 to quickly center and fix the automotive transmission on the placement table 4, facilitating press-fitting processing. During press-fitting of automotive transmission parts, the parts are assembled and placed on the placement table 4. Then, the limiting centering device 2 quickly centers them in the middle position of the placement table 4 and fixes them there, facilitating subsequent press-fitting processing, improving press-fitting efficiency and accuracy, and reducing errors caused by manual operation. During press-fitting, the cylinder 5 can be activated to move the press-fitting plate 6 downwards, pressing the automotive transmission parts on the placement table 4. It should be noted that cylinder 5 is a mature technology and equipment in the existing technology, and its internal structure, connection method and principle will not be described further.

[0033] Figure 2 and Figure 3The limiting and centering device 2 shown includes a groove frame 21, with a replacement device 3 provided between one side of the groove frame 21 and one side of the placement platform 4; a threaded rod 22, one end of which is installed through the inner wall of the groove frame 21, and the threads at both ends are in opposite directions; a servo motor 23, one side of which is fixedly installed on one side of the groove frame 21, and the output end is fixedly installed on one side of one end of the threaded rod 22 by means of a coupling; two screw hole limiting blocks 24, one end of which is slidably installed in the inner wall of the groove frame 21, and the inner wall thread is installed on the outer surface of the threaded rod 22; and several adjustment mechanisms 25, which are set in the inner walls at both ends of the screw hole limiting blocks 24 for adjusting the length of both ends of the screw hole limiting plate, thereby improving the usability of the screw hole limiting blocks 24. By setting the centering and limiting device 2, after the assembled automotive transmission parts are placed on the placement table 4, the servo motor 23 can be activated to drive the threaded rod 22 to rotate within the inner wall of the groove frame 21. This causes the two threaded hole limiting blocks 24 and the adjusting mechanism 25 to move in opposite directions. Since the openings of the two threaded hole limiting blocks 24 gradually decrease towards the bottom, during the clamping process, the inner walls at both ends will press against the outer surface of the transmission parts, pushing them towards the center, thus achieving a centering effect and limiting their movement. This allows the transmission parts placed on the placement table 4 to be quickly centered to the center of the placement table 4, directly below the pressing plate 6, facilitating subsequent pressing processes, improving pressing efficiency and accuracy, and reducing errors caused by manual operation. It should be noted that the servo motor 23 is a mature technology and equipment in the existing field, and its internal structure, connection method, and principle will not be elaborated upon further.

[0034] Figure 2 and Figure 3The adjustment mechanism 25 shown includes an adjustment limit block 251, one end of which is slidably mounted in the inner wall of one end of the screw hole limit block 24; and a plurality of first springs 252, wherein the two ends of the first springs 252 are respectively fixedly mounted on the inner wall of the screw hole limit block 24 and one side of the adjustment limit block 251. When using the screw hole limiting block 24 to limit and center the automotive transmission parts, if the size of the automotive transmission to be pressed is smaller than the inner wall size of the screw hole limiting block 24 and the adjusting limiting block 251, when it is limited, one end of the two opposing adjusting limiting blocks 251 will abut together. As the screw hole limiting block 24 moves, they abut against each other and retract into the inner wall of the screw hole block, causing the first spring 252 to contract. When limiting and centering automotive transmission parts with a larger inner wall size than the screw hole limiting block 24 and the adjusting limiting block 251, the inner wall of the adjusting limiting block 251 will abut against the transmission part, pushing it to the center. Through this adjustment, the adaptability of the screw hole limiting block 24 can be improved, making it easier to center and limit transmission parts of various sizes. The adjusting mechanism 25 also includes a limiting rod 253, one end of which is fixedly installed on one side of the inner wall of the screw hole limiting block 24, and its outer surface penetrates the inner wall of the first spring 252 and is slidably connected to the inner wall of the adjusting limiting block 251. By setting the limiting rod 253, the inner wall of the first spring 252 can be supported and reinforced, while the adjusting limiting block 251 can be limited, making it less prone to shaking during compression adjustment.

[0035] Figure 4 and Figure 5 The replacement device 3 shown includes two locking blocks 31, one side of which is fixedly installed on the bottom side of the groove frame 21. A rectangular groove 32 is provided on one side of the placement platform 4, and sliding holes 33 are symmetrically provided on one side of the inner wall of the rectangular groove 32. The groove frame 21 and the locking blocks 31 are respectively inserted into the inner walls of the rectangular groove 32 and the sliding holes 33; two locking blocks 34, one end of which is slidably installed in the inner wall of one end of the sliding hole 33, and the other end is inserted into the inner wall of the locking block 31; and several second springs 35, the two ends of which are respectively fixedly installed on one side of the locking block 34 and one side of the placement platform 4. When it is necessary to replace or maintain the groove bracket 21 and the screw hole limit block 24, the locking block 34 can be manually pulled outward in the inner wall of the sliding hole 33 to a certain position, which will cause the second spring 35 to be stretched open, so that one end of it is pulled out from the inner wall of the locking block 31. Then, the groove bracket 21 can be pulled upward to pull it out from the rectangular groove 32, so that the locking block 31 can be pulled out from the sliding hole 33, and the groove bracket 21 can be removed from the placement platform 4 for easy maintenance and replacement.

[0036] Figure 4 and Figure 5The longitudinal section of the locking block 34 shown is trapezoidal, with the end of the locking block 34 furthest from the second spring 35 being smaller than the other end. By setting the locking block 34 in a trapezoidal shape, when installing the groove bracket 21, it is not necessary to pull the locking block 34; simply insert the locking hole block 31 into the sliding hole 33 to a certain position, and the locking block 34 will slide in the sliding hole 33, facilitating installation. Several circular rollers 36 are rotatably mounted on one side of the locking block 34, and the circular rollers 36 are arranged at equal intervals. By setting the circular rollers 36, the contact friction between one side of the locking block 34 and one side of the locking hole block 31 can be reduced, making it easier to push the locking block 34 when one side of the locking hole block 31 is pressed against one side of the locking block 34. A pull block 37 is fixedly mounted on one side of the locking block 34, and the cross-section of the pull block 37 is arc-shaped. By setting the pull block 37, the contact area on one side of the locking block 34 can be increased, making it easier to manually grasp and pull, and facilitating later disassembly and replacement.

[0037] Working principle: When pressing automotive transmission parts, the parts are assembled and placed on the placement table 4. Then, the servo motor 23 is started to drive the threaded rod 22 to rotate in the inner wall of the groove frame 21, which in turn drives the two screw hole limit blocks 24 and the adjustment mechanism 25 to move in opposite directions. Since the openings of the two screw hole limit blocks 24 gradually decrease towards the bottom, during the limiting and clamping process, the inner walls at both ends will squeeze the outer surface of the transmission parts and push them towards the center, thereby achieving a centering effect and limiting them. This allows the transmission parts placed on the placement table 4 to be quickly centered to the center of the placement table 4, directly below the pressing plate 6, which facilitates subsequent pressing processing, improves pressing efficiency and accuracy, and reduces errors caused by manual operation. During pressing, the cylinder 5 can be started to drive the pressing plate 6 downward to press the automotive transmission parts on the placement table 4.

[0038] When it is necessary to replace or maintain the groove bracket 21 and the screw hole limit block 24, the locking block 34 can be manually pulled outward in the inner wall of the sliding hole 33 to a certain position, which will cause the second spring 35 to be stretched open, so that one end of it is pulled out from the inner wall of the locking block 31. Then, the groove bracket 21 can be pulled upward to pull it out from the rectangular groove 32, so that the locking block 31 can be pulled out from the sliding hole 33, and the groove bracket 21 can be removed from the placement platform 4 for easy maintenance and replacement.

[0039] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
