[0029] An automated mechanical component processing fixture comprises a fixture body 1, a guide plate 2 for guiding the clamping direction, and a motor 3. The motor 3 is arranged on the lower side of the fixture body 1, and the driving end of the motor 3 penetrates the fixture body 1 and extends into the cavity 5 and is connected to one end of the spiral center of the spring 7. The driving end of the motor 3 drives the spring 7 to contract inwardly and stretch outwardly to reset. A pair of fixing frames 4 are arranged on the bottom surface of the fixture body 1. A cavity 5 is arranged in the fixture body 1. A gusset plate 6 is arranged on the upper side of the cavity 5. A plurality of rod grooves 31 are arranged on the gusset plate 6. A spring 7 and a plurality of clamping bodies 8 for clamping the processing parts are arranged in the cavity 5. Each clamping body 8 clamps the processing parts independently. The spiral outer end of the spring 7 is fixed to the bottom surface of the inner side of the fixture body 1 by a fixing bolt, and the spiral shape of the spring 7 is used for pulling and resetting.

[0030] The clamping body 8 includes a sliding rod Ⅰ9 and a sliding rod Ⅱ10 sleeved on the outside of the sliding rod Ⅰ9, a limit block 32 is arranged on the sliding rod Ⅰ9, a slide groove 33 is arranged on the inner wall of the sliding rod Ⅱ10, and the limit block 32 is engaged in the slide groove 33 and slides along the slide groove 33, so that the sliding rod Ⅰ9 can slide stably in the sliding rod Ⅱ10, a vertical rod 11 is arranged at the left end of the sliding rod Ⅰ9, a connecting block 12 in contact with the processing part is arranged at the top of the vertical rod 11, a connecting shaft 13 is arranged at the right end of the sliding rod Ⅰ9, a thread 14 is arranged at the right end of the connecting shaft 13, and a horizontal Axis 15, a right angle frame 16 is arranged at the lower side of the sliding rod II 10, the downward extension section of the right angle frame 16 is located between the spiral gaps of the clockwork spring 7, the corner of the right angle frame 16 is hingedly connected to the horizontal axis 15, the right end of the sliding rod II 10 is provided with a through hole 17 that matches the connecting shaft 13, the connecting shaft 13 can pass through the through hole 17, and a spring II 34 is arranged near one end of the through hole 17 in the sliding rod II 10. When the sliding rod I 9 slides to the right, the spring II 34 elastically supports the sliding rod I 9 and facilitates the reset of the sliding rod I 9, and the inner diameter of the spring II 34 is larger than the diameter of the connecting shaft 13;

[0031] Two upper and lower fixing plates 18 are arranged on the right side of the sliding rod II 10, and two left and right gear brackets 19 are arranged between the fixing plates 18. A gear 20 is arranged on the gear bracket 19, and a clamping strip 21 is arranged on the fixing plate 18. A spring clamp 22 is arranged on the fixing plate 18. The spring clamp 22 includes a clamp body 23, a spring I 24 and a clamping plate 25. The clamping plate 25 is connected with the end close to the clamp body 23 through the spring I 24. When the sliding rod I 9 slides to the right, the connecting shaft 13 passes through the through hole 17 and continues to move to the right. The right side of the connecting shaft 13 is clamped by the clamping plate 25 through the thread 14, preventing the connecting shaft 13 from sliding to the left.

[0032] A matching linkage piece 26 is provided on the outside of the fixed plate 18, and a connected spring III 35 is provided between the spring card 22 and the linkage piece 26. The card body 23 and the linkage piece 26 are both slidably engaged with the card strip 21, and can slide up and down along the card strip 21. When the two card bodies 23 slide up and down respectively, the card plate 25 releases the engagement and fixation of the right end of the connecting shaft 13, so that the connecting shaft 13 can slide to the left. A plurality of meshing teeth 27 are provided on the linkage piece 26, and the meshing teeth 27 mesh with the gear 20, and the upper and lower linkages are The piece 26 performs reverse linkage movement by meshing with the gear 20. A fixing groove 28 is provided on the left wall of the linkage piece 26. A rubber strip 29 is provided in the fixing groove 28. The upper and lower linkage pieces 26 are elastically pulled by a rubber strip 29. The pulling of the linkage piece 26 by the rubber strip 29 facilitates the resetting of the linkage piece 26 after movement. A linkage rod 30 is provided on the upper side of the upper linkage piece 26. When the linkage rod 30 is pulled upward, the upper linkage piece 26 moves upward, and the lower linkage piece 26 moves downward at the same time.

[0033] The present invention provides an automated mechanical parts processing fixture, and its use method comprises the following steps:

[0034] Step 1: In the initial state, the fixture body 1 is fixed on the CNC assembly line through the fixing frame 4, each connecting block 12 is at the maximum sliding limit of the guide plate 2, and the processing part is placed in the middle of the guide plate 2.

[0035] Step 2: After the motor 3 is driven, the driving end of the motor 3 rotates to drive the mainspring 7 to contract toward the center.

[0036] Step 3: During the contraction of the spring 7, the clamping body 8 is driven to slide in the contraction direction through the right-angle frame 16. When one or more connecting blocks 12 come into contact with the processing component, the vertical rod 11 and the connecting block 12 clamp the processing component. At this time, the sliding rod I9 stops sliding. Through the continued contraction of the spring 7, the right-angle frame 16 drives the sliding rod II10 to continue to slide in the contraction direction. The connecting shaft 13 at the right end of the sliding rod I9 passes through the middle of the spring II34 and the through hole 17 and then contacts the spring card 22. The clamping plate 25 of the spring card 22 is threaded. 14 engages the connecting shaft 13, and the connecting block 12 clamps the processing component after contacting with the processing component. At the same time, the sliding rod Ⅰ9 squeezes the spring Ⅱ34 to shrink the spring Ⅱ34. After the sliding limit is reached between the sliding rod Ⅱ10 and the sliding rod Ⅰ9, the spring 7 pulls the right-angle frame 16 to make the right-angle frame 16 flip to the left side through the hinge with the horizontal axis 15, and the clamping body 8 in the component groove continues to slide in the contraction direction of the spring 7 until each clamping body 8 fixes the processing component as a whole, and sprays or other process operations are performed on the processing component.

[0037] Step 4: After the processed parts are sprayed or subjected to other process operations, the top end of the linkage rod 30 is held and pulled upward to lift the linkage rod 30, and the motor 3 is driven in the reverse direction at the same time. After the driving end of the motor 3 rotates in the reverse direction, the mainspring 7 expands and resets outward, and the linkage rod 30 drives the upper linkage piece 26 to move upward, and the lower linkage piece 26 moves downward through the engagement of the gear 20, so that the clamping plate 25 releases the fixation of the connecting shaft 13. At the same time, the expansion of the mainspring 7 squeezes the right-angle frame 16 outward to drive the sliding rod Ⅱ10 to move outward. At the same time, the elastic support of the spring Ⅱ34 accelerates the resetting process of the sliding rod Ⅱ10, and the right-angle frame 16 is rotated and reset through the hinge of the horizontal axis 15. After the resetting is completed, the processed parts can be removed from the guide plate 2.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions are deemed to be within the scope of protection of the present invention.
