[0037] The following reference Figures 1 to 10 The assembly fixture described in this invention is capable of performing step-by-step assembly of the product lower cover 410, product sleeve 420 and product upper cover 430. The assembly actions are continuous and reliable, with high assembly accuracy and high assembly efficiency.
[0038] Reference Figures 1 to 4This invention provides an assembly fixture, including a base plate 100, a stator clamping assembly 200, and a mover clamping assembly 300. The base plate 100 has an adjacent lower cover assembly station and an upper cover assembly station. The stator clamping assembly 200 is located at the lower cover assembly station and includes a lower cover mounting base 210, a lower cover clamping mechanism 220, a sliding mounting member 230, and a first elastic member 240. The lower cover mounting base 210 is fixedly connected to the base plate 100, and the lower cover clamping mechanism 220 is connected to the lower cover mounting base 210. The lower cover clamping mechanism 220 is used to fix the lower cover 410 of the product. The lower cover mounting base 210 is provided with a sliding groove 211, which extends through both sides of the lower cover mounting base 210. One end of the sliding groove 211 extends through the side wall of the lower cover mounting base 210 near the upper cover assembly station. The sliding mounting member 230 is slidable and passes through the sliding groove 211, that is, the sliding mounting member 230 can slide under the restriction of the sliding groove 211. The end of the sliding mounting member 230 near the upper cover assembly station is provided with a clamping part 231, which protrudes from the side of the lower cover mounting base 210 near the upper cover assembly station. The clamping part 231 is used to clamp the product sleeve 4. 20. The two ends of the first elastic member 240 are respectively connected to the lower cover mounting base 210 and the sliding mounting member 230, so that the clamping part 231 tends to move closer to the lower cover mounting base 210, thereby causing the product sleeve 420 to be installed onto the lower cover 410 under the action of the clamping part 231. The product sleeve 420 can be a spring, sleeve, or other structure. The mover clamping assembly 300 is located at the upper cover assembly station. The mover clamping assembly 300 includes a linear guide rail 310, an upper cover mounting base 320, and an upper cover clamping mechanism 330. The lower cover assembly station is located at one end of the linear guide rail 310, and the upper cover clamping mechanism... The upper cover mounting base 320 is connected to the upper cover mounting base 330. The upper cover clamping mechanism 330 is used to fix the product upper cover 430 to the upper cover mounting base 320. The linear guide rail 310 is connected to the base plate 100 and the upper cover mounting base 320 respectively, so as to limit the trajectory of the upper cover mounting base 320 to move towards the lower cover mounting base 210 for assembly. The upper cover mounting base 320 moves under the action of external driving force. The linear guide rail 310 can ensure that the upper cover mounting base 320 moves towards the lower cover mounting base 210 along the set movement trajectory, so as to assemble the product upper cover 430 onto the product lower cover 410 with the product sleeve 420. The first elastic element 240 can be a spring.
[0039] This invention is used for assembling a product lower cover 410, a product sleeve 420, and a product lower cover 410 with a insert rod. The specific clamping and assembly action of this invention is as follows: Refer to... Figure 8Push the sliding mounting part 230 to move the clamping part away from the lower cover mounting base 210, ensuring that a gap is formed between the clamping part and the lower cover mounting base 210. Then, insert the product lower cover 410 into the lower cover mounting base 210, and clamp and fix the product lower cover 410 to the lower cover mounting base 210 by the lower cover clamping mechanism 220. Insert the product sleeve 420 into the clamping part 231 to complete the first step of assembly preparation. Refer to Figure 9 Release the sliding mounting part 230. Under the action of the first elastic member 240, the sliding mounting part 230 slides along the sliding groove 211, so that the clamping part 231 moves closer to the lower cover mounting seat 210, thereby fitting the product sleeve 420 onto the insert of the lower cover 410. After completing the fitting and assembly action between the product sleeve 420 and the lower cover 410, that is, after completing the first assembly action, insert the upper cover 430 into the upper cover mounting seat 320 to complete the preparation action for the second assembly; refer to Figure 10 The upper cover mounting base 320 is pushed along the linear guide rail 310 to move closer to the lower cover mounting base 210, thereby assembling the upper cover 430 onto the lower cover 410 with the product sleeve 420, completing the second assembly step. Through the interconnected and cooperating structures of the assembly fixture, continuous sleeve and insertion assembly operations can be performed, eliminating the need for tedious manual alignment operations and the high cost of equipping multiple precision robotic arms for the corresponding assembly operations. This allows for high-accuracy assembly operations at a lower cost, resulting in high assembly efficiency and good assembly results.
[0040] The sliding mounting part 230, in conjunction with the first elastic element 240, can clamp the product sleeve 420 and fit the product sleeve 420 onto the corresponding structure of the product lower cover 410 on the lower cover mounting base 210. Under the guidance of the linear guide rail 310, the upper cover mounting base 320 can assemble the product upper cover 430 it clamps onto the product lower cover 410 that has been fitted with the product sleeve 420. The step-by-step assembly process is smooth and reliable. The slide groove 211 and the linear guide rail 310 can effectively ensure the assembly accuracy. The overall assembly action is stable and reliable. The assembly process does not require tedious and complicated manual alignment operations, resulting in high assembly efficiency. The overall structure of the assembly fixture is simple and compact, which can effectively save fixture costs.
[0041] Understandably, referring to Figure 2 The clamping part 231 is provided with a contoured groove 232. The shape of the contoured groove 232 matches the shape of the product sleeve 420, which can improve the stability of the position of the product sleeve 420 when it is installed in the clamping part 231. For example, when the product sleeve 420 is a product spring, the contoured groove 232 is designed as a groove structure that matches the shape of the product spring. The contoured groove 232 can form a reliable positioning effect for the product spring.
[0042] Understandably, referring to Figure 1 The moving part clamping assembly 300 also includes a second elastic element 340. The two ends of the second elastic element 340 are connected to the base plate 100 and the upper cover mounting seat 320, respectively, so that the upper cover mounting seat 320 tends to move away from the lower cover mounting seat 210. Before assembly, without external driving force, the upper cover mounting seat 320 moves away from the lower cover mounting seat 210 under the action of the second elastic element 340, ensuring a certain gap between the upper and lower cover mounting seats 210, thereby ensuring smooth assembly of the subsequent product sleeve 420, product lower cover 410, and product upper cover 430. The linear guide rail 310 is parallel to the slide groove 211, that is, the movement trajectory of the upper cover mounting seat 320 is parallel to the movement trajectory of the sliding mounting part 230. The second elastic element 340 can be a spring.
[0043] During assembly, the assembly fixture of this invention is placed in an assembly device with drive mechanisms on both sides. Neither drive mechanism needs a cumbersome fixed connection to the sliding mounting member 230 or the upper cover mounting base 320. The two drive mechanisms are used to push the sliding mounting member 230 and the upper cover mounting base 320 forward, respectively, without the need for a cumbersome fixed connection structure to drive them backward for resetting. The assembly fixture of this invention is easy to assemble, disassemble, and use. After one drive mechanism pushes the sliding mounting member 230 to mount the product sleeve 420 onto the product lower cover 410, that drive mechanism stops pushing the sliding mounting member 230. Under the action of the first elastic element 240, the mounting part 230 retracts to reset, that is, the sliding mounting part 230 moves closer to the lower cover mounting seat 210 under the action of the first elastic element 240, so as to assemble the product sleeve 420 onto the product lower cover 410. After another drive mechanism pushes the upper cover mounting seat 320 to assemble the product upper cover 430 onto the product lower cover 410, the drive mechanism stops pushing the upper cover mounting seat 320. Under the action of the second elastic element 340, the upper cover mounting seat 320 retracts to reset, that is, the upper cover mounting seat 320 moves away from the lower cover mounting seat 210 under the action of the second elastic element 340, thus preparing for the next assembly action. In batch operation, multiple assembly fixtures are placed side by side in the assembly equipment. The drive mechanism in the assembly equipment can drive multiple assembly fixtures to perform assembly operations simultaneously, resulting in high assembly efficiency and simplifying the layout design of the assembly equipment.
[0044] Understandably, referring to Figure 5The bottom of the upper cover mounting base 320 is provided with a receiving groove 321. A third elastic element 322 and a positioning element 323 are provided in the receiving groove 321. The two ends of the third elastic element 322 are respectively connected to the positioning element 323 and the upper cover mounting base 320, so that the positioning element 323 tends to move away from the upper cover mounting base 320. The end of the third elastic element 322 away from the positioning element 323 is specifically connected to the inner wall of the receiving groove 321. The base plate 100 is provided with a plug-in positioning structure, which is used to plug in the positioning element 323 to position the upper cover mounting base 320 at the end of the linear guide rail 310 near the lower cover mounting base 210. This ensures that after the upper cover mounting base 320 assembles the product upper cover 430 onto the product lower cover 410 with the product sleeve 420, it will not immediately spring back to its original position, thereby effectively improving the reliability of the assembly operation. The third elastic element 322 can be a spring.
[0045] Understandably, referring to Figure 1 and Figure 5 The insertion and positioning structure includes an adjustment block 110, which has a positioning hole 111. The adjustment block 110 is movable and connected to the base plate 100. The positioning hole 111 is used to insert the positioning component 323.
[0046] Specifically, the adjusting block 110 is also provided with an adjusting groove 112, and the base plate 100 is provided with a screw hole 101. The screw 113 passes through the adjusting groove 112 and is threadedly connected to the screw hole 101 so that the adjusting block 110 is fixed to the base plate 100. After loosening the screw 113, the adjusting block 110 can be pushed to move relative to the base plate 100. The screw 113 slides in the adjusting groove 112 to adjust the position of the adjusting block 110, thereby adjusting the position of the upper cover mounting seat 320. This can ensure assembly accuracy and can adapt to the assembly operation of different products to a certain extent. Tightening the screw 113 to lock it in the screw hole 101 can fix the adjusting block 110 to the base plate 100.
[0047] Understandably, the positioning element 323 is configured as a column or a ball bearing. The column enhances the positioning effect of the insertion positioning structure on the upper cover mounting base 320. When locked, the column automatically engages with the positioning hole 111 under the action of the third elastic element 322. When unlocked, an external pin is inserted into the end of the positioning hole 111 away from the upper cover mounting base 320, thereby pushing the column away from the positioning hole 111, thus ensuring that the upper cover mounting base 320 can retract and reset under the action of the second elastic element 340. The ball bearing enables automatic locking and unlocking.
[0048] It is understandable that, in addition to including the adjustment block 110, the insertion and positioning structure can also have the positioning hole 111 directly set on the base plate 100. The positioning hole 111 is used for the insertion of the positioning component 323 to achieve positioning of the upper cover mounting base 320.
[0049] Understandably, referring to Figure 4 The linear guide 310 includes a guide rail 311 and a slider 312. The slider 312 is slidably connected to the guide rail 311. The linear guide 310 is fixedly connected to the base plate 100, and the slider 312 is fixedly connected to the upper cover mounting base 320.
[0050] Understandably, referring to Figure 6 and Figure 7 The lower cover mounting base 210 is also provided with a lower cover mounting groove 212 and a movable cavity 213. The lower cover mounting groove 212 is used to install the lower cover 410 of the product. The lower cover clamping mechanism 220 includes a clamping member 221 and a fourth elastic member 222 both disposed in the movable cavity 213. One end of the clamping member 221 protrudes into the lower cover mounting groove 212. The two ends of the fourth elastic member 222 are respectively connected to the clamping member 221 and the lower cover mounting base 210, so that the clamping member 221 tends to move closer to the lower cover mounting groove 212, thereby pressing the lower cover 410 of the product into the lower cover mounting groove 212. This can effectively eliminate the installation error caused by the width tolerance of the lower cover 410 of the product, thereby improving the assembly accuracy. The end of the fourth elastic member 222 away from the clamping member 221 is specifically connected to the inner wall of the movable cavity 213. The fourth elastic member 222 can be a spring.
[0051] Understandably, referring to Figure 2 , Figure 6 and Figure 7 The clamping member 221 includes a clamping arm 221A, a linkage arm 221B, and an inclined guide block 221C. One end of the clamping arm 221A is connected to one end of the linkage arm 221B, and the other end of the clamping arm 221A protrudes into the interior of the lower cover mounting groove 212. The clamping member 221 is rotatably connected to the lower cover mounting base 210. The rotation axis of the clamping member 221 is located at the connection between the linkage arm 221B and the clamping arm 221A. One end of the fourth elastic member 222 is connected to... The linkage arm 221B is connected so that the clamping arm 221A tends to move closer to the lower cover mounting groove 212. The inclined guide block 221C is connected to one end of the clamping arm 221A that protrudes from the lower cover mounting groove 212. The inclined guide block 221C is used to drive the clamping arm 221A to rotate and make room under the installation thrust of the lower cover 410, so as to ensure that the lower cover 410 can be smoothly installed into the lower cover mounting groove 212 and clamped by the clamping arm 221A. When the product lower cover 410 is installed, it is inserted into the lower cover mounting groove 212 from top to bottom. When the product lower cover 410 contacts the inclined guide block 221C, the inclined guide block 221C drives the clamping arm 221A and the linkage arm 221B to rotate under the downward pressure of the product lower cover 410, so that the clamping arm 221A makes way for the product lower cover 410. When the product lower cover 410 is fully inserted into the lower cover mounting groove 212, the clamping arm 221A clamps the product lower cover 410 in the lower cover mounting groove 212 under the action of the fourth elastic element 222.
[0052] Specifically, the slide groove 211 extends along the y-axis, the sliding mounting member 230 can move along the y-axis, the linear guide rail 310 is parallel to the y-axis, that is, the movement direction of the upper cover mounting base 320 is parallel to the y-axis, the rotation axis of the clamping member 221 is parallel to the z-axis, and the clamping member 221 can rotate in the xy plane. The top of the inclined guide block 221C is provided with a guide slope, which faces the opening of the lower cover mounting groove 212. When the lower cover 410 is placed into the lower cover mounting groove 212, the lower cover 410 pushes the clamping arm 221A away from the lower cover mounting groove 212 under the action of the guide slope to make room, ensuring that the lower cover 410 can be effectively placed into the lower cover mounting groove 212. Under the action of the first elastic member 240, the clamping arm 221A can effectively clamp the lower cover 410 into the lower cover mounting groove 212. The insertion and installation of the lower cover 410 is convenient and does not require the cooperation of other structures.
[0053] It is understandable that the clamping arm 221A is located on one side of the movement trajectory of the clamping part 231, which can prevent the clamping arm 221A from hindering the sliding mounting part 230 from performing the fitting and assembly action on the product sleeve 420 and the product lower cover 410. The clamping arm 221A is located on one side of the movement trajectory of the upper cover mounting base 320, which can prevent the clamping arm 221A from hindering the upper cover mounting base 320 from performing the assembly action on the product upper cover 430 and the product lower cover 410. The assembly action of the overall assembly fixture is stable and reliable.
[0054] Understandably, referring to Figure 1 The lower cover clamping mechanism 220 also includes a lower cover pressing member 223, which is rotatably connected to the lower cover mounting base 210. The lower cover pressing member 223 is located above the lower cover mounting groove 212. The lower cover pressing member 223 is used to press the lower cover 410 of the product into the lower cover mounting groove 212. The lower cover pressing member 223 is located above the movement trajectory of the clamping part 231, which can prevent the lower cover pressing member 223 from obstructing the fitting and assembly action of the sliding mounting part 230. The lower cover pressing member 223 is located above the movement trajectory of the upper cover mounting base 320, which can prevent the lower cover pressing member 223 from obstructing the assembly action performed by the upper cover mounting base 320.
[0055] Specifically, the rotation axis of the lower cover pressing component 223 is parallel to the x-axis, and the rotation axis of the clamping component 221 is parallel to the z-axis. The lower cover pressing component 223 can work with the clamping component 221 to achieve a more comprehensive clamping and positioning effect on the lower cover 410 of the product, thereby effectively improving the reliability of the assembly action.
[0056] Understandably, referring to Figure 2The upper cover mounting base 320 is provided with an upper cover mounting groove 324, which is used to install the product upper cover 430. The upper cover mounting groove 324 is provided with a guide piece 325, which is used to guide and adjust the position of the product upper cover 430 to ensure that the product upper cover 430 is stably and firmly installed in the upper cover mounting groove 324, thereby ensuring the reliability of subsequent assembly operations.
[0057] Specifically, two guide plates 325 are provided. The top of each guide plate 325 has a guiding slope facing the other guide plate 325. The guide plate 325 with the guiding slope is used to reduce damage to the product cover 430 caused by installation errors. The product cover 430 has a high installation error tolerance. By guiding and positioning the product cover 430 through the two guide plates 325, wear between the product cover 430 and the cover mounting base 320 can be effectively reduced, thus ensuring the service life of the cover mounting base 320. It also prevents the product cover 430 from becoming defective due to wear during assembly. Especially for product covers 430 made of easily worn materials such as foam, the guide plates 325 provide an automatic alignment and guidance effect, effectively preventing wear on the product cover 430. Optionally, the guide plate 325 can be a spring-loaded piece, which can improve the positioning effect of the product cover 430.
[0058] Understandably, referring to Figure 2 The upper cover mounting base 320 is also provided with a clearance groove 326. The movement trajectory of the clamping part 231 is collinear with the movement trajectory of the clearance groove 326. The clearance groove 326 is used to accommodate one end of the sliding mounting member 230 where the clamping part 231 is provided. When the upper cover mounting base 320 moves close to the lower cover mounting base 210, one end of the sliding mounting member 230 where the clamping part 231 is provided is inserted into the clearance groove 326, which can position the upper cover mounting base 320 and the sliding mounting member 230 to ensure the stability of the position of the product sleeve 420 when the product upper cover 430 is assembled to the product lower cover 410, and avoid the position of the product sleeve 420 that has been assembled to the product lower cover 410 from shifting, thereby effectively improving the assembly accuracy and the reliability of the assembly action. Specifically, when the upper cover mounting base 320 moves close to the lower cover mounting base 210 and assembles the upper cover 430 onto the lower cover 410, one end of the sliding mounting member 230 with the clamping part 231 is inserted into the relief groove 326. The position of the sliding mounting member 230 can remain stable, thereby ensuring that the position of the product sleeve 420 clamped by the clamping part 231 at one end is stable relative to the upper cover 430 and the lower cover 410. This avoids the product sleeve 420 shifting position when assembling the upper cover 430 and the lower cover 410, which could lead to defective products.
[0059] Understandably, referring to Figure 2The lower cover mounting base 210 is provided with a first anti-deviation block 214 on the side near the upper cover mounting base 320, and the upper cover mounting base 320 is provided with a second anti-deviation block 327 on the side near the lower cover mounting base 210. The first anti-deviation block 214 is provided with a first anti-deviation inclined surface, and the second anti-deviation block 327 is provided with a second anti-deviation inclined surface that is opposite to the first anti-deviation inclined surface. The first anti-deviation inclined surface and the second anti-deviation inclined surface are parallel. The first anti-deviation block 214 is located at one end of the movement trajectory of the second anti-deviation block 327, and the first anti-deviation block 214 is used to limit the movement of the second anti-deviation block 327. Under the action of external driving force, the second anti-deviation block 327 moves close to the first anti-deviation block 214 along with the upper cover mounting base 320. When the first anti-deviation inclined surface and the second anti-deviation inclined surface come into contact, the first anti-deviation block 214 and the second anti-deviation block 327 form a close contact relationship, which can effectively improve the positional stability between the upper cover mounting base 320 and the lower cover mounting base 210, thereby effectively improving the reliability of the assembly action performed by the assembly fixture on the product upper cover 430 and the product lower cover 410.
[0060] Understandably, referring to Figure 6 The cover clamping mechanism 330 includes a cover pressing member 331 and a fifth elastic member 332. The cover pressing member 331 is rotatably connected to the cover mounting base 320. The cover pressing member 331 is located above the cover mounting groove 324 and the lower cover mounting groove 212, preventing the cover pressing member 331 from obstructing the assembly action of the cover mounting base 320. The two ends of the fifth elastic member 332 are respectively connected to the cover pressing member 331 and the cover mounting base 320, so that the cover pressing member 331 tends to move closer to the cover mounting groove 324, thereby pressing the product cover 430 tightly onto the cover mounting groove 324. The fifth elastic member 332 can be a spring.
[0061] Specifically, the rotation axis of the upper cover pressing component 331 is parallel to the x-axis, and the linear guide rail 310 is parallel to the y-axis. That is, the movement direction of the upper cover mounting base 320 is parallel to the y-axis. The upper cover pressing component 331 presses the product upper cover 430 against the upper cover mounting base 320 from the y-axis side, which can further avoid the upper cover pressing component 331 from hindering the assembly action of the upper cover mounting base 320.
[0062] It is understandable that one end of the cover pressing component 331 is provided with a contouring structure, which matches the shape of the product cover 430, and is used to achieve a more stable and reliable pressing and positioning operation on the product cover 430, which can effectively prevent the product cover 430 from shifting in other directions.
[0063] Understandably, referring to Figure 2 and Figure 6The upper cover mounting base 320 is also provided with an embedded positioning block 328. The embedded positioning block 328 is connected to the side of the upper cover mounting groove 324 away from the lower cover mounting base 210. The upper cover 430 of the product is provided with an insert rod, and the lower cover 410 of the product is provided with a rod sleeve connected to the insert rod. The embedded positioning block 328 is used to position the rod sleeve in the lower cover 410 of the product to improve the stability of the insert rod in the upper cover 430 being inserted into the rod sleeve in the lower cover 410 of the product. The specific processing action is as follows: the sliding mounting part 230 first installs the product sleeve 420 into the insert rod of the upper cover 430 of the product, and then the upper cover mounting base 320 connects the rod sleeve of the lower cover 410 of the product to one end of the insert rod. The product sleeve 420 is located between the upper cover 430 of the product and the lower cover 410 of the product. The upper cover 430 of the product and the lower cover 410 of the product can also be connected by inserting a pin into the upper cover 430 of the product and the lower cover 410 of the product through external equipment to realize the rotational connection between the upper cover 430 of the product and the lower cover 410 of the product.
[0064] Specifically, the top of the inlaid positioning block 328 is provided with a positioning slope, which is used to guide the product cover 430, thereby effectively improving the reliability of the product cover 430 installed in the cover mounting groove 324. For the product cover 430 made of easily worn materials such as foam, the positioning slope on the top of the inlaid positioning block 328 can provide an automatic alignment guide for the product cover 430, effectively preventing the product cover 430 from being worn.
[0065] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
