[0024] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0025] See Figures 1-6 A positioning device for machining includes a machining platform 1, a dustproof plate 2, and a support plate 11. The dustproof plate 2 is fixedly installed on the upper surface of the machining platform 1. A cleaning component 3 is provided above the machining platform 1. The cleaning component 3 includes a motor 301 and two dust covers 304. The motor 301 is detachably installed on the outer surface of the dustproof plate 2. The motor 301 is installed on the outer surface of the dustproof plate 2 by bolts, which facilitates the subsequent disassembly and maintenance of the motor 301.

[0026] Both dust covers 304 are connected to the inner wall of the dust cover 2 and are located on the outer surface of the dust cover 2. When the workpiece is being drilled, the dust cover 304 can block the flying debris generated during drilling and let the debris fall into the collection bin 308 below for convenient subsequent unified processing.

[0027] The output end of the motor 301 is fixedly connected to the first gear 302. The inner wall of the rear dust cover 304 is rotatably connected to the threaded rod 305. The other end of the threaded rod 305 passes through the front dust cover 304 and is rotatably connected to the inner wall of the front dust cover 304. The front end of the threaded rod 305 is fixedly connected to the second gear 303. The first gear 302 and the second gear 303 mesh. By utilizing the meshing between the first gear 302 and the second gear 303, the motor 301 can be started after drilling to drive the second gear 303 to rotate, which facilitates the subsequent cleaning brush 307 to clean the debris on the surface of the processing platform 1.

[0028] The outer surface of the threaded rod 305 is threadedly connected to a movable block 306. The outer surface of the movable block 306 is slidably connected to the inner walls of the two dust covers 304 and the inner wall of the dust plate 2. The inner walls of the two dust covers 304 and the inner wall of the dust plate 2 are provided with sliding grooves that are adapted to the movable block 306, which allows the movable block 306 to move in the sliding grooves, while restricting the movable block 306 from rotating with the threaded rod 305.

[0029] A cleaning brush 307 is fixedly connected to the outer surface of the dust cover 304. The bottom end of the cleaning brush 307 contacts the upper surface of the processing platform 1. The cleaning assembly 3 also includes two collection chambers 308. Both collection chambers 308 are snapped into the processing platform 1. The outer surface of the processing platform 1 is provided with a slot that matches the collection chamber 308. After the debris collected inside the collection chamber 308 reaches a certain level, the collection chamber 308 can be removed to facilitate the subsequent dumping of debris.

[0030] An L-shaped door 4 is provided on the outside of the dustproof panel 2. A limiting component 5 is provided on the outside of the L-shaped door 4. The outer surface of the L-shaped door 4 is in contact with the outer surface of the dustproof panel 2, and the contact point is relatively sealed, which can prevent debris from being scattered out from the gaps.

[0031] The limiting component 5 includes two fixing blocks 501 and a connecting block 503. The bottom surfaces of the two fixing blocks 501 are fixedly connected to the upper surface of the dustproof plate 2. The fixing blocks 501 are equipped with torsion springs inside. The torsion springs are used to reset the L-shaped door 4. When the L-shaped door 4 is closed with the dustproof plate 2, the torsion springs inside the fixing blocks 501 are under stress. When the limiting of the L-shaped door 4 is released, the torsion springs inside the fixing blocks 501 will immediately reset and drive the L-shaped door 4 to open, so as to facilitate the removal of the processed workpiece.

[0032] The connecting block 503 is fixedly installed on the outer surface of the dustproof plate 2. The inner walls of the two fixed blocks 501 are rotatably connected with rotating rods 502. The two rotating rods 502 are respectively fixedly connected to one end of the torsion spring on the inner wall of the two fixed blocks 501. The side of the two rotating rods 502 that are close to each other are fixedly connected to the outer surface of the L-shaped door 4. The L-shaped door 4 can be rotated by the rotating rods 502, which makes it convenient to put the workpiece into the dustproof plate 2 and ensures the normal use of the subsequent device.

[0033] A limiting rod 504 is slidably connected to the inner wall of the connecting block 503. The end of the limiting rod 504 near the L-shaped door 4 is fixedly connected to the outer surface of the L-shaped door 4. An arc-shaped limiting block 505 is slidably connected to the inner wall of the connecting block 503. The material of the connecting block 503 can deform to avoid interference when limiting the L-shaped door 4. When the limiting rod 504 contacts the arc-shaped surface of the arc-shaped limiting block 505, the arc-shaped limiting block 505 will move upward to stretch the first spring 507. When the limiting rod 504 moves to the rear of the arc-shaped limiting block 505, the arc-shaped limiting block 505 will immediately pop out to limit the limiting rod 504, thereby limiting the L-shaped door 4 and preventing the L-shaped door 4 from opening and causing debris to fly out when processing the workpiece.

[0034] A movable rod 506 is fixedly connected to the top of the arc-shaped limiting block 505. The movable rod 506 is slidably connected to the upper surface of the connecting block 503. A first spring 507 is sleeved on the outer surface of the movable rod 506, and the two ends of the first spring 507 are fixedly connected to the upper surface of the connecting block 503 and one end of the movable rod 506, respectively. Pulling the movable rod 506 can release the limitation on the limiting rod 504, thereby opening the L-shaped door 4 and facilitating the removal of the processed workpiece.

[0035] The bottom of the processing platform 1 is provided with four shock-absorbing components 10. Each of the four shock-absorbing components 10 includes a sleeve 1001. The sleeve 1001 is fixedly installed on the upper surface of the support plate 11. A second spring 1002 is fixedly connected to the inner bottom wall of the sleeve 1001. A damper 1003 is fixedly connected to the end of the second spring 1002 away from the sleeve 1001. A moving column 1004 is fixedly connected to the end of the damper 1003 away from the second spring 1002. The outer surfaces of the damper 1003 and the moving column 1004 are slidably connected to the inner wall of the sleeve 1001. The upper surface of the moving column 1004 is fixedly connected to the bottom surface of the processing platform 1. Through the cooperation between the second spring 1002 and the damper 1003, the impact force generated when the drill bit 7 contacts the workpiece can be absorbed during the processing of the workpiece, thereby achieving a shock-absorbing effect and preventing the device from vibrating and affecting the processing accuracy.

[0036] A cylinder 6 is fixedly installed on the upper surface of the dustproof plate 2. The output end of the cylinder 6 passes through the inner wall of the dustproof plate 2 and is fixedly connected to a drill bit 7. An electric telescopic rod 8 is fixedly installed on the inner top wall of the dustproof plate 2. A clamping plate 9 is fixedly connected to the telescopic end of the electric telescopic rod 8. A rubber pad is provided on the bottom surface of the clamping plate 9, which can increase the friction when in contact with the workpiece and reduce the damage to the workpiece surface when clamping the workpiece.

[0037] Working principle: In use, when it is necessary to clean debris from the surface of the processing platform 1, the motor 301 is first started to drive the first gear 302 to rotate. The meshing relationship between the first gear 302 and the second gear 303 makes the threaded rod 305 more stable during rotation. The rotation of the threaded rod 305 causes the moving block 306 to move on the outer surface of the threaded rod 305, thereby allowing the cleaning brush 307 to sweep away debris from the surface of the processing platform 1. The swept debris is then moved by the cleaning brush 307 to the dust cover 304. When the debris falls into the collection chamber 308 below, it achieves the effect of cleaning the surface of the processing platform 1, preventing the debris from accumulating on the top of the processing platform 1 and affecting the accuracy of subsequent workpiece positioning. When processing the workpiece, closing the L-shaped door 4 slides the limiting rod 504 into the interior of the connecting block 503, and the arc-shaped limiting block 505 limits the limiting rod 504, which can prevent debris from flying everywhere during processing and affecting the working environment. At the same time, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
