[0008] Preferably, a first spring is fitted onto the arc surface of the slide rod, and the first spring is fixedly connected to the inclined block and the circular pad respectively.

[0009] The effect achieved by the above components is that when the frustum column presses down on the inclined block along the fixed column, the inclined block will push the slide rod and compress the first spring, causing the spring to generate elastic force. When the frustum part of the frustum column is below the inclined block, the elastic force will cause the slide rod to automatically spring back to its original position, locking the frustum column and preventing it from being pulled upwards.

[0016] Preferably, a second spring is fitted onto the arc surface of each of the two pins, and the second spring is fixedly connected to the slide plate and the rectangular plate respectively.

[0017] The effect achieved by the above components is that when the two pins are pulled out of the socket using the slide, the second spring will generate elastic force. When the position of the pins is moved and the slide is released, the elastic force can cause the pins to automatically insert into the socket.

[0018] Preferably, a handle is fixedly connected to the side of the skateboard away from the rectangular plate, and the cross-section of the handle is U-shaped.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figures 1 to 4This utility model provides a quick-change machining tool fixture, comprising: a base plate 1 and a fixing device 7 for clamping the tool. A slide groove 2 is provided on the upper surface of the base plate 1. A lead screw 3 is rotatably connected to the inner wall of the slide groove 2. A first motor 4 is fixedly connected to one side of the base plate 1. The output end of the first motor 4 is fixedly connected to the lead screw 3. A slider 5 is slidably connected to the inner wall of the slide groove 2. The slider 5 is threadedly connected to the lead screw 3. A support plate 8 is fixedly connected to the upper surface of the base plate 1. A second motor 9 is fixedly connected to the support plate 8. A grinding assembly 10 is rotatably connected to one side of the support plate 8. The output end of the second motor 9 is fixedly connected to the grinding assembly 10. A locking device 6 is provided on the upper surface of the slider 5.

[0032] In the embodiments of this utility model, please refer to Figure 2 and Figure 3 The locking device 6 includes a base 601. Two rectangular grooves 602 are formed on the upper surface of the base 601. Two sliding sleeves 603 are fixedly connected to the inner walls of each of the two rectangular grooves 602. A round pad 605 is fixedly connected to the end of each sliding sleeve 603 that is close to each other. A sliding rod 604 is slidably connected to the inner wall of each sliding sleeve 603. An inclined block 609 is fixedly connected to the end of each sliding rod 604 that is close to each other, and a connecting button 607 is fixedly connected to the end of each sliding rod 604 that is far from each other. A circular groove 611 is formed on the inner wall of the two rectangular grooves 602. A fixing post 612 is fixedly connected to the inner wall of the circular groove 611. A frustum column 613 is slidably connected to the arc surface of the fixing post 612. The frustum column 613 is a hollow column. A mounting plate 614 is fixedly connected to the upper surface of each of the two frustum columns 613. This allows the fixing device 7 mounted on the mounting plate 614 to be quickly fixed and quickly detached through the locking device 6, thereby achieving the effect of quick replacement of the clamp. A first spring 606 is fitted onto the arc surface of the slide rod 604, and the first spring 606 is fixedly connected to the inclined block 609 and the circular pad 605. This achieves the effect that when the frustum 613 is pressed downwards along the fixed column 612, the inclined block 609 pushes the slide rod 604 and compresses the first spring 606, causing the spring to generate elastic force. When the frustum portion of the frustum 613 is below the inclined block 609, the elastic force causes the slide rod 604 to automatically spring back to its original position, locking the frustum 613 and preventing it from being pulled upwards. Several anti-slip patterns 608 are evenly distributed on the arc surface of the two connecting buttons 607. This achieves the effect that when the slide rod 604 is pulled using the connecting buttons 607, the anti-slip patterns 608 increase the surface friction of the connecting buttons 607, preventing slippage during pulling. Both sides of the inclined block 609 are rotatably connected to pulleys 610, and the arc surface of the pulleys 610 is slidably connected to the inner wall of the rectangular groove 602. When the frustum 613 presses the inclined block 609 downward, the pulleys 610 will slide along the inner wall of the rectangular groove 602, which increases the transmission efficiency of the slide rod 604.

[0033] In the embodiments of this utility model, please refer to Figure 4 and Figure 5 The fixing device 7 includes a connecting plate 701, which is L-shaped. Two elliptical grooves 702 are formed at the long wall end of the connecting plate 701, and two rows of vertically arranged insertion holes 703 are formed at the long arm end. A sliding column 704 is fixedly connected to the lower surface of the short arm end of the connecting plate 701. The sliding column 704 is fixedly connected to the mounting plate 614. An L-shaped plate 705 is slidably connected to the arc surface of the sliding column 704. A fixing tube 706 is fixedly connected to the short arm end of the L-shaped plate 705, and the fixing tube 706 completely penetrates the L-shaped plate 705. A screw 707 is threaded onto the arc surface of tube 706. Two connecting rods 708 are fixedly connected to the long arm end of L-shaped plate 705. Both connecting rods 708 are slidably connected to elliptical groove 702. The ends of the two connecting rods 708 away from L-shaped plate 705 are fixedly connected to the same rectangular plate 709. Two pins 710 are slidably connected to one side of rectangular plate 709. A limiting rod 713 is fixedly connected to one side of rectangular plate 709. A sliding plate 712 is slidably connected to the arc surface of limiting rod 713. The sliding plate 712 is fixedly connected to the pins 710. This achieves the effect of clamping and fixing the tool, as well as moving and fixing the position of L-shaped plate 705. A second spring 711 is sleeved on the arc surface of each of the two pins 710. The second spring 711 is fixedly connected to the sliding plate 712 and rectangular plate 709, respectively. When the two pins 710 are pulled out of the socket 703 using the slide plate 712, the second spring 711 generates a spring force. After moving the position of the pins 710 and releasing the slide plate 712, the spring force allows the pins 710 to automatically insert into the socket 703. A handle 714 is fixedly connected to the side of the slide plate 712 away from the rectangular plate 709. The handle 714 has a "U" shaped cross-section. This allows the slide plate 712 to be pulled using the handle 714, making operation simpler and more convenient.

[0034] The working principle of the quick-change machining tool fixture provided by this utility model is as follows: When machining tools, it is usually necessary to change different types of fixtures. The locking device 6 can realize the quick installation and disassembly of the fixture, which speeds up the maintenance efficiency of the fixture. The main operation steps are as follows: When the fixture needs to be installed, firstly, the fixture needs to be installed on the mounting plate 614. Then, the fixture can be slowly lowered from top to bottom through the mounting plate 614. During the process of placing the mounting plate 614, the two frustums 613 on the lower surface of the mounting plate 614 need to be aligned with the fixing post 612 located in the lower rectangular groove 602. 13. As the frustum 613 slides down the fixed post 612, its truncated cone shape presses against the inclined blocks 609 on both sides of the fixed post 612. During this pressing process, the two inclined blocks 609 move away from each other. Simultaneously, the inclined blocks 609 push the connected sliding rod 604 away from each other. As the sliding rod 604 slides, it compresses the first spring 606 on its arc surface. This compression generates friction with the inclined blocks 609. 9. The spring force moving in the opposite direction causes the slide bar 604 to slide along the inner wall of the sliding sleeve 603 located within the base 601 during its movement. Simultaneously, as the inclined block 609 moves, the two pulleys 610 below it roll along the surface of the rectangular groove 602, increasing the efficiency of the inclined block 609's movement. As the frustum 613 presses against the inclined block 609, when the frustum portion of the frustum 613 successfully slides along the fixed column 612 to below the inclined surfaces of the two inclined blocks 609, the frustum 613 will no longer press against the inclined block 609. Thus, the inclined block 609 will automatically... When the clamp springs back to its original position, the two inclined blocks 609 will be positioned above the frustum 613, thus restricting the upward movement of the frustum 613. At this time, the frustum 613 will also be in the circular groove 611, further restricting its left and right movement, thereby enabling the installation of the clamp. When the clamp needs to be disassembled, the connecting button 607 located at one end of the slide bar 604 needs to be pulled manually. Pulling the connecting button 607 away from the base 601 will cause the inclined blocks 609 to move away from each other through the slide bar 604. At this time, the mounting plate 614 can be lifted upward, thus pulling the frustum 613 upward, thereby disassembling the clamp.

[0035] The specific operation of the fixing device 7 in this utility model is as follows: When it is necessary to clamp and fix the machining tool, firstly, the tool needs to be placed inside the fixing tube 706 along the fixing tube 706. After placement, the screw 707 can be rotated. During the rotation, the screw 707 moves into the fixing tube 706 by means of the thread inside the fixing tube 706. After the screw 707 moves downward and squeezes and fixes the tool, the rotation of the screw 707 can be stopped. At this time, the second motor 9 can be used to rotate the lead screw 3, and the slider 5 drives the base 601 and the clamp to move towards the grinding assembly 10 to start machining the tool. When it is necessary to machine different positions of the tool, the handle 714 can be used to pull the slide plate 712 away from the connecting plate 701. When the slide plate 712 is pulled, the slide plate 712 will drive the connected... The two pins 710 move in the same direction. During the movement of the slide plate 712, the second spring 711 is extended, thereby generating elastic force. At the same time, the slide plate 712 also slides along the limiting rod 713. When the two pins 710 are pulled out of the insertion hole 703, due to the limiting rod 713, the pins 710 will not disengage from the rectangular plate 709 to prevent the second spring 711 from twisting and deforming. At this time, the handle 714 can be used to slide the L-shaped plate 705 along the inner wall of the elliptical groove 702 through the two connecting rods 708. During this process, the L-shaped plate 705 will also slide along the sliding column 704 to adjust the position of the cutter. When the cutter is moved to the appropriate position, the handle 714 is slowly released. The pins 710 will move towards the insertion hole 703 due to the elastic force of the second spring 711, thereby inserting into the insertion hole 703 and fixing the L-shaped plate 705.

[0036] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
