Description

Technical Field

[0033] Example 1, referring to Figures 1-4 As a first embodiment of the present invention, a testing device for automobile spring production is provided, which, through the bonding mechanism 200, can adapt to springs of different sizes while preventing the springs from bending.

[0034] The testing mechanism 100 includes a base 101, an electric telescopic cylinder 102 is fixedly connected to the left side of the top of the base 101, a lower pressure plate 103 is fixedly connected to the output end of the electric telescopic cylinder 102, and a placement seat 104 is movably connected to the left side inside the base 101.

[0035] The bonding mechanism 200 includes bonding rods 201, which are arranged on the top of the placement seat 104 and are distributed in a ring at equal intervals. The top of the bonding rods 201 extends through to the top of the lower pressure plate 103 and is movably connected to the lower pressure plate 103. The placement seat 104 has a movable groove 202 inside, and a clamping component 203 is movably connected inside the movable groove 202. The placement seat 104 has an installation groove 204 on the left side inside, which is connected to the movable groove 202. A power-off component 205 is movably connected inside the installation groove 204.

[0036] The clamping assembly 203 includes a turntable 203a, with an arc groove 203b on the top of the turntable 203a. Several arc grooves 203b are formed and are distributed in a ring at equal intervals. The top of the placement seat 104 has a sliding groove 203c, with several sliding grooves 203c formed and distributed in a ring at equal intervals. The sliding groove 203c is connected to the movable groove 202. A movable shaft 203d is movably connected inside the arc groove 203b. The top end of the movable shaft 203d passes through the interior of the sliding groove 203c and is movably connected to the sliding groove 203c. The top end of the movable shaft 203d is fixedly connected to the bottom of the fitting rod 201. A motor 203e is fixedly connected to the bottom of the placement seat 104. The output end of the motor 203e is fixedly connected to the bottom of the turntable 203a.

[0037] The power-off assembly 205 includes a gear 205a, which is movably connected inside the mounting groove 204. The top of the surface of the turntable 203a has a toothed groove 205b, which is provided in a ring and is evenly distributed. The gear 205a meshes with the toothed groove 205b. The front and rear sides of the top left side of the placement seat 104 are fixedly connected to a contact button 205c. The front side of the contact button 205c is movably connected to a connecting bracket 205d. The bottom end of the connecting bracket 205d extends into the mounting groove 204 and is fixedly connected to the top of the gear 205a. The contact button 205c is electrically connected to the electric telescopic cylinder 102 through an external controller.

[0038] A reinforcing plate 206 is fixedly connected to the outer side of the fitting rod 201. Two reinforcing plates 206 are provided, and the reinforcing plates 206 are movably connected to the placement seat 104.

[0039] The bottom end of the movable shaft 203d is fixedly connected to a limiting block 207, and the limiting block 207 is movably connected to the arc groove 203b.

[0040] The bottom of the turntable 203a is movably inlaid with balls 208. Several balls 208 are arranged in a ring and are evenly distributed. The balls 208 are movably connected to the inner wall of the movable groove 202.

[0041] Specifically, the clamping assembly 203 can drive the bonding rod 201 to move inward to clamp and bond with the spring.

[0042] The power-off component 205 can cut off the power to the electric telescopic cylinder 102 when the bonding rod 201 is not moving inward.

[0043] The reinforcing plate 206 can reinforce the bonding rod 201, thereby ensuring the stability of the bonding rod 201 during use.

[0044] The limiting block 207 can limit the movement of the movable shaft 203d, preventing the movable shaft 203d from separating from the arc groove 203b.

[0045] The ball bearing 208 can reduce the friction between the turntable 203a and the inner wall of the movable groove 202.

[0046] Furthermore, the motor 203e is started. After the motor 203e starts, it can drive the turntable 203a inside the movable groove 202 to rotate. After the turntable 203a rotates, it can drive the movable shaft 203d to move inward through the arc groove 203b and the sliding groove 203c. The movable shaft 203d can drive the top bonding rod 201 to move inward to clamp and bond the spring.

[0047] When the turntable 203a rotates, it drives the gear 205a inside the mounting groove 204 to rotate through the tooth groove 205b. After the gear 205a rotates, it can drive the connecting frame 205d to rotate. As the connecting frame 205d rotates, it can separate from the contact button 205c, so that the contact button 205c can open the electric telescopic cylinder 102 to be in the energized state.

[0048] The user can then use the electric telescopic cylinder 102 to drive the pressure plate 103 to press down and test the spring that limits the contact of the contact rod 201.

[0049] Example 2, refer to Figures 1-5 In a second embodiment of the present invention, an inspection device for automobile spring production is provided, which facilitates the placement and removal of springs through a feeding mechanism 300.

[0050] The feeding mechanism 300 includes a groove 301, which is opened on the top of the placement seat 104. A lifting plate 302 is movably connected inside the groove 301. Inclined components 303 are opened on the front and rear sides of the inner wall of the base 101. An air injection component 304 is fixedly connected to the front and rear sides of the bottom left side of the placement seat 104.

[0051] The tilting component 303 includes a guide groove 303a, and guide blocks 303b are fixedly connected to both sides of the front and back of the placement seat 104. The guide blocks 303b are movably connected to the guide groove 303a.

[0052] The air injection assembly 304 includes a fixed plate 304a, an airbag 304b fixedly connected to the right side of the fixed plate 304a, a sliding frame 304c fixedly connected to the right end of the airbag 304b, the left end of the sliding frame 304c extending through to the left side of the fixed plate 304a and movably connected to the fixed plate 304a, a spring 304d fixedly connected to the bottom right side of the fixed plate 304a, the right end of the spring 304d fixedly connected to the left side of the sliding frame 304c, a stop block 304e fixedly connected to the bottom right side of the inner wall of the base 101, the stop block 304e movably connected to the sliding frame 304c, a multi-stage telescopic air rod 304f fixedly connected to the front and rear sides of the inside of the groove 301, the top end of the multi-stage telescopic air rod 304f fixedly connected to the bottom of the lifting plate 302, and the airbag 304b communicating with the multi-stage telescopic air rod 304f.

[0053] A traction frame 305 is provided on the right side of the placement seat 104. A shaft frame 306 is fixedly connected to both the front and rear sides of the right side of the placement seat 104. The traction frame 305 is movably connected to the shaft frame 306.

[0054] A positioning block 307 is fixedly connected to the top of the lifting plate 302.

[0055] Specifically, the tilting component 303 enables the placement seat 104 to tilt as a whole to facilitate the placement of the spring.

[0056] The air injection component 304 can drive the lifting plate 302 to move upward, pushing the spring upward for easy handling.

[0057] The use of the traction frame 305 and the shaft frame 306 makes it convenient for users to pull and push the placement seat 104.

[0058] The spring on the lifting plate 302 can be initially positioned by the positioning block 307.

[0059] Furthermore, when it is necessary to remove the spring, pull the traction frame 305, so that the traction frame 305 drives the placement seat 104 to move to the right inside the base 101 through the shaft frame 306, so that the placement seat 104 can drive the guide block 303b to move inside the guide groove 303a. When the guide block 303b moves to the rightmost end of the guide groove 303a, the placement seat 104 is in an inclined state, which will cause the spring inside the fitting rod 201 to be in an inclined state.

[0060] When the placement seat 104 moves to the right, the sliding frame 304c will contact the abutment block 304e. As the placement seat 104 moves, the sliding frame 304c will squeeze the airbag 304b on the fixing plate 304a and squeeze the spring 304d. As the airbag 304b is squeezed, gas can be injected into the multi-stage telescopic air rod 304f, so that the multi-stage telescopic air rod 304f can push the lifting plate 302 inside the groove 301 to move upward, so that the lifting plate 302 can push the spring upward, making it easy for the user to remove the spring.

[0061] The spring is placed on the lifting plate 302 and initially positioned by the positioning block 307.

[0062] Then push the placement seat 104 to the left to reset. At this time, the spring can push the sliding frame 304c to reset through its elastic force. After the sliding frame 304c is reset, it can stretch the airbag 304b. At the same time, the spring will press down the lifting plate 302, causing the multi-stage telescopic air rod 304f at the bottom of the lifting plate 302 to retract and inject gas into the airbag 304b, so that the lifting plate 302 is reset.

[0063] The remaining structure is the same as that in Example 1.

[0064] Example 3, referring to Figures 1-5 This is the third embodiment of the present invention, which differs from the second embodiment in that it is a testing device for automobile spring production.

[0065] When the spring needs to be removed, pull the traction frame 305, so that the traction frame 305 drives the placement seat 104 to move to the right inside the base 101 through the shaft frame 306, so that the placement seat 104 can drive the guide block 303b to move inside the guide groove 303a. When the guide block 303b moves to the rightmost end of the guide groove 303a, the placement seat 104 is tilted as a whole, which will cause the spring inside the fitting rod 201 to tilt.

[0066] When the placement seat 104 moves to the right, the sliding frame 304c will contact the abutment block 304e. As the placement seat 104 moves, the sliding frame 304c will squeeze the airbag 304b on the fixing plate 304a and squeeze the spring 304d. As the airbag 304b is squeezed, gas can be injected into the multi-stage telescopic air rod 304f, so that the multi-stage telescopic air rod 304f can push the lifting plate 302 inside the groove 301 to move upward, so that the lifting plate 302 can push the spring upward, making it easy for the user to remove the spring.

[0067] When it is necessary to test the spring, the spring is placed on the lifting plate 302 and initially positioned by the positioning block 307.

[0068] Then push the placement seat 104 to the left to reset. At this time, the spring can push the sliding frame 304c to reset through its elastic force. After the sliding frame 304c is reset, it can stretch the airbag 304b. At the same time, the spring will press down the lifting plate 302, causing the multi-stage telescopic air rod 304f at the bottom of the lifting plate 302 to retract and inject gas into the airbag 304b, so that the lifting plate 302 is reset.

[0069] Then, the motor 203e is started. After the motor 203e starts, it can drive the turntable 203a inside the movable groove 202 to rotate. After the turntable 203a rotates, it can drive the movable shaft 203d to move inward through the arc groove 203b and the sliding groove 203c. The movable shaft 203d can drive the top bonding rod 201 to move inward to clamp and bond the spring.

[0070] When the turntable 203a rotates, it drives the gear 205a inside the mounting groove 204 to rotate through the tooth groove 205b. After the gear 205a rotates, it can drive the connecting frame 205d to rotate. As the connecting frame 205d rotates, it can separate from the contact button 205c, so that the contact button 205c can open the electric telescopic cylinder 102 to be in the energized state.

[0071] The user can then use the electric telescopic cylinder 102 to drive the pressure plate 103 to press down and test the spring that limits the contact of the contact rod 201.

[0072] In summary, the spring is limited and prevented from bending by the bonding rod 201 inside the bonding mechanism 200, and the unloading mechanism 300 allows the user to easily remove the spring from the placement seat 104 or place it on the placement seat 104.
