Description

A high-efficiency precision positioning device for metal stamping parts Technical Field

[0001] This application relates to the field of metal stamping processing technology, and more specifically, to a high-efficiency precision positioning device for metal stamping parts. Background Technology

[0002] Metal stamping parts, as an indispensable and important part of modern manufacturing, are widely used in various fields such as automobiles, electronics, electrical appliances, and machinery. In the production process of metal stamping parts, the metal sheet first needs to be cut into blanks of the required size. Then, under the action of stamping dies, the blanks undergo multiple stamping, stretching, forming and other processes to gradually form complete parts.

[0003] In related technologies, different fixing devices are usually required for stamped parts of different sizes. For example, patent CN218638403U provides a positioning and adjustment device for processing metal stamped parts. This device adjusts the position of the positioning block by sliding a movable block inside the adjustment groove. The screw thread is moved to the position inside the slot to fix the movable block. Pressing the extrusion block causes the movable plate to rotate in a rotating shape around the pivot, causing the fixed block to disengage from the position inside the fixed groove. At the same time, the movable plate extrudes the deformation cylinder to deform. The extrusion block is released at the appropriate position, and the deformation force of the deformation cylinder clamps the fixed block into the corresponding position inside the fixed groove, thus fixing the slide plate in place. By adjusting the position of the positioning block according to the different sizes of stamped parts, the equipment operating cost is reduced and waste is avoided.

[0004] Although the existing technical solutions mentioned above can achieve the effect of positioning stamped parts of different sizes by setting a movable block to slide and adjust the position of the positioning block inside the adjustment groove, the shape of the positioning block is set as a block with right angles, which is not conducive to the positioning of complex or special shaped metal stamped parts.

[0005] In view of this, we propose a high-efficiency precision positioning device for metal stamping parts. Summary of the Invention

Detailed Implementation

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] Referring to Figures 1, 2, and 5, this application discloses an efficient precision positioning device for metal stamping parts, including a stamping table 1. The top of the stamping table 1 has four sliding grooves 11. A clamping assembly 2 is provided on the top of the stamping table 1. The clamping assembly 2 includes two symmetrically arranged clamping blocks A21 and two symmetrically arranged clamping blocks B22. The two clamping blocks A21 and the two clamping blocks B22 are slidably disposed on the top of the stamping table 1 through the corresponding sliding grooves 11. A lifting plate 3 is provided on the top of the stamping table 1. The lifting plate 3 is raised and lowered under the drive of external force. A pushing assembly 4 is provided on the outer side of the lifting plate 3. The pushing assembly 4 is used to drive the two clamping blocks A21 and the two clamping blocks B22 to position the metal stamping parts.

[0029] When in use, the metal stamping parts are first placed on the top of the stamping table 1. When the upper mold is stamping, the lifting plate 3 is driven down by the external equipment, which in turn drives the pushing component 4 down, thereby driving the two clamping blocks A21 and two clamping blocks B22 to slide on the top of the stamping table 1 to clamp the metal stamping parts.

[0030] The two clamping blocks A21 and the two clamping blocks B22 are slidably disposed on the top of the stamping table 1 through the corresponding slide grooves 11, and the contact ends of the two clamping blocks A21 and the two clamping blocks B22 with the metal stamping parts are set as inclined surfaces, so that the metal stamping parts are subjected to the lateral and top thrusts from the clamping blocks A21 and the clamping blocks B22 when they are clamped and positioned.

[0031] Referring to Figures 2, 3, 4, and 5, sliders A211 are fixedly installed at the bottom of both clamping blocks A21, and sliders B221 are fixedly installed at the bottom of both clamping blocks B22. Sliding sliders A211 and B221 are slidably disposed on the inner side of their respective sliding grooves 11. Adjusting bolts A212 are rotatably installed on the outer side of both clamping blocks A21. The outer sides of the two adjusting bolts A212 are threaded onto the inner side of their respective connecting plates A213. Both sides of the two connecting plates A213 are fixedly provided with… A horizontal plate A214 has a connecting seat A215 fixedly installed on its outer side. A wedge block A216 is fixedly installed on the outer side of each of the four connecting seats A215. The top of each of the four wedge blocks A216 is a sloping surface A2161. Four fixing blocks 12 are fixedly installed at the bottom of the stamping table 1. Springs 217 are installed on the inner side of each of the four horizontal plates A214. U-shaped fixing seats 218 are fixedly installed at both ends of each of the four springs 217. The four outer U-shaped fixing seats 218 are connected by corresponding connecting bolts A218. 1. The corresponding horizontal plate A214 is detachably installed. The four inner U-shaped fixing seats 218 are all fixed to the corresponding fixing blocks 12 by corresponding connecting bolts A2181. Mounting plates 15 are fixedly installed on both sides of the stamping table 1. Adjusting bolts B222 are rotatably installed on the outer side of the two clamping blocks B22. The outer side of the two adjusting bolts B222 is threaded to the inner side of the connecting seat B225. Tension springs 224 are fixedly installed on the inner side of the two connecting seats B225. The side of the two tension springs 224 that is far away from each other is... The connecting plate B223 and connecting bolt B2231 are fixedly installed with the corresponding mounting plate 15. The outer side of each of the two connecting seats B225 is fixedly provided with a wedge B226. The top of each of the two wedges B226 is set as a wedge B2261. The pushing assembly 4 includes six connecting plates C41. The bottom of each of the six connecting plates C41 is fixedly provided with a wedge C42. The bottom of each of the six wedges C42 is set as a wedge C421. The six wedges C421 respectively cooperate with the corresponding wedge A2161 or wedge B2261.

[0032] When the lifting plate 3 descends, it drives the six connecting plates C41 to descend, thereby causing the inclined surfaces C421 of the six inclined blocks C42 to engage with the corresponding four inclined surfaces A2161 and two inclined surfaces B2261. The inclined surfaces A2161 of the four inclined blocks A216, after being pushed by the corresponding inclined surfaces C421, drive the corresponding connecting seats A215 to move, thereby driving the corresponding horizontal plates A214 to move, which in turn drives the two connecting plates A213 to move. The two connecting plates A213 then drive the corresponding sliders A211 to slide within the corresponding grooves 11, thus allowing the two... The clamping block A21 moves, thereby clamping and fixing the two sides of the metal stamping part. At the same time, the inclined surfaces B2261 of the two inclined blocks B226 are pushed by the corresponding inclined surfaces C421, which drives the connecting seat A215 to move, thereby driving the corresponding slider B221 to slide inside the corresponding slide groove 11, so that the two clamping blocks B22 clamp and fix the other two sides of the metal stamping part. The two sides are provided by the two horizontal plates A214 and the two connecting seats A215, so that the pushing part is located on both sides of the stamping table 1, which makes it convenient for the staff to pick up and put down the metal stamping part.

[0033] After stamping is completed, the lifting plate 3 rises under the drive of external force, which drives the pushing component 4 to rise, releasing the contact between the inclined block C42 and the inclined block A216 and inclined block B226. The four connecting seats A215 are reset under the elastic force of the four springs 217, and the two connecting seats B225 are reset under the tension of the two tension springs 224, thereby causing the two clamping blocks A21 and the two clamping blocks B22 to slide and reset.

[0034] By rotating the corresponding adjusting bolt A212, which engages with the nut fixed inside the corresponding connecting plate A213, the distance between the corresponding clamping block A21 and the corresponding connecting plate A213 can be adjusted. By rotating the corresponding adjusting bolt B222, which engages with the nut fixed inside the corresponding connecting seat B225, the distance between the corresponding clamping block B22 and the corresponding connecting seat B225 can be adjusted. Thus, the positions of the two clamping blocks A21 and the two clamping blocks B22 can be adjusted, making it suitable for asymmetrical metal stamping parts.

[0035] Referring to Figures 1 and 2, four limiting posts 13 are fixedly installed on the top of the stamping table 1. The outer side of the limiting posts 13 is slidably installed with the inner side of the lifting plate 3. The top of the stamping table 1 is provided with a mounting groove 14. The top of the lifting plate 3 is provided with a mounting seat 31. The lifting plate 3 can be raised and lowered under the drive of external force, such as by two hydraulic cylinders 100. The output end of the hydraulic cylinders 100 is fixedly installed with the top of the lifting plate 3. The outer side of the two hydraulic cylinders 100 is jointly provided with a fixing plate 1001. Four support posts 1002 are fixedly installed at the bottom of the fixing plate 1001. The bottom of the four support posts 1002 is fixedly installed with the top of the stamping table 1. The outer side of the four support posts 1002 is slidably installed with the lifting plate 3. The outer side of the stamping table 1 is provided with a shell 16.

[0036] The lifting plate 3 is limited by four limit posts 13, the lower mold can be installed through the mounting slot 14, and the lower mold can be installed through the mounting base 31.

[0037] The lifting plate 3 can be raised and lowered under the drive of external force, for example, by two hydraulic cylinders 100 to drive the lifting plate 3 to rise and fall, so that the lifting plate 3 slides on the outside of the four support columns 1002.

[0038] In summary, the high-efficiency precision positioning device for metal stamping parts disclosed in this application, when in use, uses external force to drive the lifting plate 3 to descend, thereby causing the six connecting plates C41 to descend. This causes the inclined surfaces C421 of the six inclined blocks C42 to engage with the corresponding four inclined surfaces A2161 and two inclined surfaces B2261. When the inclined surfaces A2161 of the four inclined blocks A216 are pushed by the corresponding inclined surfaces C421, they cause the corresponding connecting seats A215 to move, thereby causing the corresponding horizontal plate A214 to move, which in turn causes the two connecting plates A213 to move. The two connecting plates A213 cause the corresponding sliders A211 to slide within the corresponding slide grooves 11, thereby causing the two clamping blocks A21 to move and clamping and fixing the two sides of the metal stamping part. Simultaneously, when the inclined surfaces B2261 of the two inclined blocks B226 are pushed by the corresponding inclined surfaces C421, they cause the connecting seats A215 to move, thereby causing the corresponding horizontal plates A214 to move. The slider B221 slides inside the corresponding groove 11, allowing the two clamping blocks B22 to clamp and fix the other two sides of the metal stamping part. The two sides are provided by two horizontal plates A214 and two connecting seats A215, so that the pushing part is located on both sides of the stamping table 1, which facilitates the worker to pick up and put down the metal stamping part. By rotating the corresponding adjusting bolt A212, the adjusting bolt A212 cooperates with the nut fixed inside the corresponding connecting plate A213, which can adjust the distance between the corresponding clamping block A21 and the corresponding connecting plate A213. By rotating the corresponding adjusting bolt B222, the adjusting bolt B222 cooperates with the nut fixed inside the corresponding connecting seat B225, which can adjust the distance between the corresponding clamping block B22 and the corresponding connecting seat B225. Thus, the positions of the two clamping blocks A21 and the two clamping blocks B22 can be adjusted, making it suitable for asymmetrical metal stamping parts.
