The worktable is hinged to the front end of the base. Multiple mounting slots are provided, all located inside the worktable. The mounting seat is slidably connected to the upper surface of the worktable. Multiple fixing bolts are slidably connected to the inner sides of the mounting slots and inserted into the inner side of the mounting seat. Multiple fastening nuts are threadedly connected to the upper ends of the fixing bolts. The adjusting seat is slidably connected to the upper surface of the mounting seat. The workpiece is placed on the upper surface of the adjusting seat. This invention achieves clamping and positioning of the workpiece, improving work efficiency.

[0004] Existing technologies include a worktable, fixing bolts, clamping and positioning mechanisms, etc., which together form a positioning device to achieve the function of positioning and clamping. By placing the workpiece on the adjusting seat, the workpiece is clamped by the threaded rod driving the clamping rod. The device has multiple sets of mounting slots and fixing bolts, which makes it inconvenient to quickly install and move it to the machine tool, thus affecting the efficiency of use. Clamping by the clamping rod can easily damage the surface of the workpiece, affecting the clamping effect. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary positioning device for CNC machine tools, so as to at least partially solve the problems of existing positioning devices.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an auxiliary positioning device for CNC machine tools, comprising a base structure, the base structure including a worktable, with support columns fixedly installed on both sides of the bottom of the worktable, and mounting seats provided at the bottom of the support columns.

[0010] Furthermore, circular mounting holes are symmetrically distributed on both sides of the top of the worktable, and the mounting holes extend to the bottom of the worktable. Motors in the drive assembly are movably placed on both sides of the worktable.

[0011] Furthermore, the motor has power ports on both sides, one end of the power port is fixedly connected to a wire, and the other end of the wire is electrically connected to both sides of the fixed base in the positioning structure.

[0012] By installing a suitable pad at the bottom of the clamping plate, the soft pad is less likely to cause wear to the workpiece surface when clamping and fixing, thus ensuring the integrity of the workpiece's exterior and improving the practicality of the positioning device. At the same time, the pad is fixed by the top fixing bolts, which makes it easy to replace periodically and improves the flexibility of the device.

[0013] Furthermore, the fixed base is equipped with an electrical board inside, which is fixedly connected to one end of an electrical wire. Telescopic columns are installed on both sides of the top of the fixed base, and telescopic springs are sleeved on the outside of the telescopic columns. The telescopic columns are movably connected to the inside of the mounting holes.

[0014] Furthermore, the fixed base is movably connected to the clamping plate on both sides by bolts. The clamping plate has two sets of centrally symmetrically distributed clamping plates. A through hole is opened on the top of the clamping plate. The through hole is a circular hole. A fixing bolt is installed inside the through hole and fixedly connected to the pad.

[0015] Furthermore, a slider is fixedly installed at the center of the bottom of the fixed base. The slider is the same size as the groove and slides along both sides inside the groove.

[0016] This utility model has the following beneficial effects:

[0017] (1) This utility model: It is equipped with a positioning structure that is easy to install. After the clamping plate and the fixed base are fixed and installed by bolts, it can be placed on both sides of the base structure for quick installation and use. This allows the positioning device to be installed in different positions according to the actual situation, thereby improving the installation efficiency.

[0018] (2) This utility model: By installing a suitable pad at the bottom of the clamping plate, the soft pad is less likely to cause wear on the surface of the workpiece when performing clamping and fixing, thereby ensuring the integrity of the workpiece exterior and improving the practicality of the positioning device. At the same time, the pad is fixed by the fixing bolts at the top, making it easy to replace regularly and improving the flexibility of the device.

Slide grooves 104 and mounting holes 105 are provided on both sides of the top of the worktable 101. Drive components 2 are installed on both sides of the worktable 101. The drive components 2 include a motor 201 and wires 202. Both sides of the motor 201 are connected to one end of the wires 202. One end of the wires 202 is connected to both sides of the fixed base 301 in the positioning structure 3. The positioning structure 3 includes a fixed base 301. Telescopic columns 302 are provided on the top of the fixed base 301. Clamping plates 303 are installed on both sides of the fixed base 301. Adaptive pads 304 are installed at the bottom of the clamping plates 303.

[0030] The positioning structure 3 is designed for easy installation. After the clamping plate 303 is fixed to the fixed base 301 with bolts, it can be placed on both sides of the base structure 1 for quick installation and use. This allows the positioning device to be installed in different positions according to the actual situation, thereby improving the installation efficiency.

[0031] The bottom of the workbench 101 is fixedly connected to the top of the support column 102. The bottom of the support column 102 is fixedly fitted with a mounting base 103. The top two sides of the workbench 101 are provided with strip-shaped slide grooves 104, which extend to the middle of the workbench 101.

[0032] The top of the workbench 101 has circular mounting holes 105 symmetrically distributed on both sides. The mounting holes 105 extend to the bottom of the workbench 101. The motors 201 of the drive assembly 2 are movably placed on both sides of the workbench 101.

[0033] The motor 201 has power ports on both sides. One end of the power port is fixedly connected to the inside of the power port, and the other end of the power cable 202 is electrically connected to both sides of the fixed base 301 in the positioning structure 3.

[0034] The fixed base 301 has an internal power board, which is fixedly connected to one end of the wire 202. Telescopic columns 302 are installed on both sides of the top of the fixed base 301. Telescopic springs are sleeved on the outside of the telescopic columns 302, and the telescopic columns 302 are movably connected to the inside of the mounting hole 105.

[0035] The fixed base 301 is movably connected to the clamping plate 303 on both sides by bolts. The clamping plate 303 has two sets of centrally symmetrically distributed clamping plates. The top of the clamping plate 303 has a through hole, which is circular. The pad 304 is fixed by the top fixing bolt 305, which is easy to replace periodically and improves the flexibility of the device. The fixing bolt 305 is installed inside the through hole and fixedly connected to the pad 304. By installing the matching pad 304 at the bottom of the clamping plate 303, the soft pad 304 is less likely to cause wear to the surface of the workpiece when performing clamping and fixing, thus ensuring the integrity of the workpiece's exterior and improving the practicality of the positioning device.

[0036] A slider is fixedly installed at the center of the bottom of the fixed base 301. The slider is the same size as the slide groove 104 and slides along both sides inside the slide groove 104.

[0037] The working principle of this CNC machine tool auxiliary positioning device is as follows: During use, the positioning device is placed in the corresponding position on the CNC machine tool. The height of the clamping plate 303 in the positioning structure 3 is adjusted according to the position of the machine tool. After the clamping plate 303 is fixed to the fixed base 301 with bolts, it can be quickly installed and used by placing it on both sides of the base structure 1, improving installation speed. The height of the clamping plate 303 is adjusted by the telescopic column 302 in conjunction with the telescopic spring to suit the fixed position of the machine tool. The motors 201 on both sides are powered on and drive the clamping plate 303 to fix the positions of the workpiece on both sides, keeping the workpiece in the corresponding position. When the clamping plate 303 fixes the workpiece position, the bottom mounting pad 304 minimizes friction damage to the outside of the workpiece, enhancing the accuracy of the machine tool's machining position. The slider at the bottom of the fixed base 301 moves outwards from the slide groove 104, allowing the machine tool to perform machining work, thus ensuring continuous machining work in the corresponding position and improving machining efficiency.
