[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a tooling fixture for machining, comprising: a base plate 1, a support column 2 fixedly installed at the middle of the upper end of the base plate 1, a rotating cylinder 4 rotatably sleeved at the outer end of the support column 2, a retaining ring 3 fixedly installed at the lower end of the support column 2, the diameter of the retaining ring 3 being larger than the diameter of the rotating cylinder 4, the lower end of the rotating cylinder 4 being located at the upper end of the retaining ring 3, clamping grooves 5 symmetrically fixedly installed at the left and right ends of the rotating cylinder 4, a support leg 10 fixedly installed at the lower side of the end of the clamping groove 5 away from the rotating cylinder 4, a round block 11 fixedly installed at the lower end of the support leg 10, a ball bearing 12 rotatably connected to the lower end of the round block 11, one end of the outer wall of the ball bearing 12 being rolledly connected to the upper end of the base plate 1, supporting the clamping groove 5 on the upper end of the base plate 1, when the clamping groove 5 moves, the ball bearing 12 rolls on the base plate 1, and the clamping groove 5 can rotate on the base plate 1 with the support column 2 as the center, thereby changing the position of the clamping groove 5.

[0022] The bottom end of the clamping groove 5 is provided with a strip-shaped hole 6. The inner end of the clamping groove 5 is connected to a clamping block 8 by a spring 7. The outer wall of the clamping block 8 is slidably connected to the inner wall of the clamping groove 5. One end of the spring 7 is fixed to the inner wall of the clamping groove 5, and the other end is fixed to the side wall of the clamping block 8. The clamping block 8 can move in the clamping groove 5 by compressing the spring 7. One end of the workpiece to be drilled is pressed against one side of the clamping block 8 and pushed inward, thereby driving the clamping block 8 to move in the clamping groove 5. Then, the other end of the workpiece is placed in the clamping groove 5. After releasing the hand, the workpiece is clamped by the reaction force of the spring 7.

[0023] Anti-slip pads 9 are fixedly installed on the inner wall of the end of the clamping groove 5 away from the spring 7 and on the outer wall of the clamping block 8. The anti-slip pads 9 increase the friction between the workpiece and the clamping block 8 and the inner wall of the clamping groove 5, making the workpiece clamped more stably.

[0024] Support plates 13 are fixedly installed at the diagonal corners on the left and right sides of the upper end of the base plate 1. The support plates 13 are L-shaped. The upper end of the support plate 13 has a strip hole 17 and a sliding sleeve 18 is slidably fitted thereon. Several drill sleeves 19 are evenly fixedly installed on the side wall of the sliding sleeve 18. A threaded hole 16 is opened on one side of the upper end of the support plate 13. Several through holes 20 are evenly opened on one end of the sliding sleeve 18. A hand-tightening bolt 21 is inserted into one of the through holes 20. One end of the hand-tightening bolt 21 passes through the through hole 20 and is threaded to the inner wall of the threaded hole 16 to fix the sliding sleeve 18. Each through hole 20 corresponds to the position of a drill sleeve 19, which facilitates quick adjustment and fixation of the position of the drill sleeve 19.

[0025] A cylinder 14 is fixedly installed on the inner side of the lower end of the support plate 13, and a baffle 15 is fixedly installed on the outer end of the cylinder 14. The outer wall of the baffle 15 can contact the outer wall of one end of the clamping groove 5, thereby positioning the clamping groove 5 so that the part of the workpiece that needs to be drilled can be quickly and accurately moved to the lower end of the drill sleeve 19 for quick drilling.

[0026] When this device is in operation, first install it on the mounting platform of the drilling equipment. Move the corresponding drill sleeve 19 to the upper end of the threaded hole 16 using the sliding sleeve 18 and fix it with the hand-tightening bolt 21. Place one end of the workpiece to be drilled against one side of the clamping block 8 and push it inward to drive the clamping block 8 to move in the clamping groove 5. Then place the other end of the workpiece in the clamping groove 5. After releasing the hand, the workpiece is clamped by the reaction force of the spring 7. Then rotate the clamping groove 5 so that one end contacts the baffle 15, and the drilling equipment can be started to drill the workpiece.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
