Description

Technical Field

[0001] The utility model relates to the technical field of automobile production and processing, in particular to an automobile production and processing jig. Background Art

[0002] Existing automobile production and processing limit elements are unable to collect and process the waste generated during the processing of metal parts in time during production and processing. Generally, industrial vacuum cleaners, dust collectors and other equipment are used to collect and process the waste, or the waste in the factory is cleaned regularly. However, if the debris is not cleaned in time, the processing accuracy will be reduced and the surface quality of the processed parts will be affected. For this reason, Chinese patent document publication number CN219293328U discloses a waste collection and cutting fixture for cutting automobile rearview mirrors. The key points of its technical solution include a bottom plate, two side plates, a box material bracket and a cross beam. The two side plates are symmetrically fixed to the upper end surface of the bottom plate in a front-to-back manner. The waste collection and cutting fixture for cutting automobile rearview mirrors has an air pipe interface connected to the air pipe arranged on the side of the adsorption fixture. The air pipe interface is connected to an external vacuum pump through a connecting pipe and an exhaust pipe. The two adsorption fixtures generate suction through the extraction effect of the vacuum pump.

[0003] However, this method has strict requirements on the size of waste materials and can only allow extremely small particles of non-ferromagnetic metal debris to pass through. When encountering metal debris with strong ferromagnetism that adsorb each other into a cluster, the waste cannot be collected. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 5 The utility model provides a technical solution: an automobile production and processing fixture, comprising a workbench 1, a blanking trough 407 is opened at the top center of the workbench 1, a bottom plate 5 is fixed to the middle of the supporting legs of the workbench 1, a reversing assembly 4 is installed on the top of the bottom plate 5, the reversing assembly 4 includes an outer box 401 installed on the top of the bottom plate 5 and capable of reciprocating swing, a magnetic block 402 is slidably installed on the inner box wall of the outer box 401, and the magnetic block 402 and the inner wall of the outer box 401 near the rotation point are connected by a spring 405, a pulley 404 is coaxially fixed to the outer box 401, and a tension rope 403 that bypasses the pulley 404 is connected between the magnetic block 402 and the bottom plate 5.

[0023] When the fixture is in use, metal debris slides from the drop chute 407 to the top of the outer box 401. At this time, the magnetic block 402 fits with the top inner wall of the outer box 401 under the thrust of the spring 405, and absorbs the metal debris that falls to the top of the outer box 401, thereby completing the automatic collection of the metal debris.

[0024] And driven by the external structure, the outer box 401 can rotate with the shaft seat 406 as the center. When the outer box 401 rotates, the tension rope 403 is wound in the groove on the pulley 404, pulling the magnetic block 402 to slide along the inner wall of the outer box 401 and away from the top of the outer box 401 until the magnetic block 402 releases the adsorption of the metal debris, and the collected metal debris can be transferred automatically.

[0025] After the chip removal is completed, the outer box 401 can reciprocate with the shaft seat 406 as the center under the drive of the external structure. At this time, the pulling force of the tension rope 403 on the magnetic block 402 gradually decreases. Under the action of the spring 405, the magnetic block 402 moves along the inner wall of the outer box 401, approaches and fits the top of the outer box 401, and can continue to collect the newly generated metal debris;

[0026] Through the reciprocating swing of the outer box 401 and the reciprocating sliding of the magnetic block 402, the metal debris can be automatically collected and directional discharged, and each processing element can be individually collected and discharged, thereby improving the processing surface accuracy and surface quality.

[0027] Furthermore, two connecting blocks 202 are installed on the top surface of the workbench 1, and a clamping block 201 is installed on the connecting block 202. A slide groove is opened on the top of the workbench 1, and a slider 301 is installed in the slide groove for horizontal sliding. A screw rod 203 is rotatably installed on the outer wall of the slider 301. One end of the screw rod 203 passes through the outside of the workbench 1 and is threadedly connected to the through-hole of the workbench 1. A rotating handle 204 is installed on the other end of the screw rod 203.

[0028] When it is necessary to place a processing element, the screw rod 203 is driven to rotate forward or backward by rotating the rotating handle 204, and the slider 301 is pushed forward or backward, so as to adjust the relative positions of the two clamping blocks 201 respectively installed on the two connecting blocks 202, limit the processing element, adapt to processing elements of different sizes, and improve the scope of application.

[0029] Furthermore, a gear 304 is rotatably mounted on the bottom of the workbench 1 near the slider 301 through a fixed frame 302, a rack is fixed to the bottom of the slider 301, and the rack is meshed with the gear 304, a sprocket 303 is coaxially fixed to the gear 304 and the pulley 404, and the two sprockets 303 are driven by a chain.

[0030] When the slider 301 slides, the rack at the bottom drives the gear 304 and the sprocket 303 to rotate, and the sprocket 303 drives the pulley 404 to rotate through the chain transmission, and drives the return assembly 4 to rotate;

[0031] Thus, when the two clamping blocks 201 are relatively close to each other, the outer box 401 rotates toward the bottom of the blanking chute 407, and the magnetic block 402 also slides toward the top of the outer box 401, and can absorb the metal debris on the top surface of the outer box 401. When the two clamping blocks 201 are relatively far away from each other, the outer box 401 rotates toward the bottom plate 5, and the magnetic block 402 slides toward the bottom of the outer box 401, gradually releasing the absorption of the metal debris on the top surface of the outer box 401.

[0032] In this way, when the two clamping blocks 201 clamp the workpiece, the outer box 401 is located below the blanking chute 407 for receiving materials. After processing, when the two clamping blocks 201 release the clamping effect on the workpiece, the outer box 401 automatically rotates and completes the transfer of metal debris, saving the time of cleaning the debris on the surface of the workbench 1 after removing the workpiece, thereby improving work efficiency.

[0033] Furthermore, a groove is formed on the top of the outer box 401 .

[0034] When metal debris falls to the top of the outer box 401, the groove on the top of the outer box 401 can increase the receiving area to prevent the metal debris from escaping from the top of the outer box 401, and when the magnetic block 402 is away from the top of the outer box 401, it prevents the metal debris from falling off prematurely due to the reduction of suction.

[0035] Furthermore, the cross-sectional area of ​​the blanking trough 407 gradually decreases from top to bottom.

[0036] The receiving area of ​​the metal chips falling from the top of the drop chute 407 is increased, and the metal chips are gathered to prevent the metal chips from passing through the drop chute 407 and then escaping from the top of the outer box 401 .

[0037] Furthermore, the surfaces of the clamping blocks 201 that are close to each other are all provided with serrated grooves.

[0038] The friction between the two clamping blocks 201 and the processing element can be increased, thereby improving the stability of the processing element during processing.

[0039] Furthermore, a waste box 6 is provided on one side of the bottom of the base plate 5 .

[0040] When the metal scraps are transferred along the outer box 401 , they are received and stored by the waste box 6 .

[0041] Furthermore, the clamping block 201 can be slidably adjusted on the connecting block 202 by means of bolts.

[0042] When in use, the bolt on the top of the clamp block 201 can be removed, and the relative position between the clamp block 201 and the connecting block 202 can be adjusted by sliding, so as to further improve the scope of application.

[0043] Working principle: When the automobile production and processing jig is used, first place the processing element above the blanking chute 407, and then turn the rotating handle 204 to allow the two clamping blocks 201 to limit the processing element. At this time, the reversing component 4 will automatically return to a position perpendicular to the blanking chute 407 and start processing. The metal debris generated during the processing will fall and be adsorbed in the groove at the top of the outer box 401. When the processing is completed, turn the rotating handle 204 until the two clamping blocks 201 are released from limiting the processing element. At the same time, the reversing component 4 rotates to transfer the metal debris to the top of the waste box 6, and gradually releases the adsorption of the metal debris by the magnetic suction block 402, allowing the metal debris to fall into the waste box 6.

[0044] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
