Description

Technical Field

[0001] The present application belongs to the technical field of handboard finishing, and in particular, relates to a CNC handboard engraving fixture. Background Art

[0002] CNC, also known as numerical control machine tools, refers to an automated machine tool equipped with a program control system. Before a product is produced, a product sample needs to be made, and this sample is also called a prototype. Prototypes are the first step to verify the feasibility of a product, and are the most direct and effective way to find out the defects, deficiencies, and drawbacks of a designed product. During the processing of prototypes, not only must they be processed according to the complete CNC processing steps, but they must also ensure the accuracy of each step of processing.

[0003] The existing Chinese patent with publication number CN211966714U discloses a CNC fixture for processing handboards, which belongs to the field of handboard finishing devices. The key points of its technical solution include a disc, a mounting insertion hole is opened in the center of the disc, a clamping block is arranged on the disc, a sliding groove is opened on the circumferential side wall of the disc, the sliding groove passes through the side wall of the disc close to the clamp, and a positioning block fixed to the disc is arranged at one end of the sliding groove away from the mounting insertion hole; a screw rod is arranged in the sliding groove, and a smooth rod is coaxially arranged at one end of the screw rod away from the mounting insertion hole, the smooth rod passes through the positioning block and is rotatably connected with the positioning block, a rotating ring groove coaxial with the smooth rod is opened in the positioning block, and a limiting ring protrudes from the circumferential side wall of the smooth rod toward the rotating ring groove; a positioning rod is vertically arranged in the sliding groove for the disc, a sliding ring threadedly connected to the screw rod is fixed at one end of the positioning rod close to the sliding groove, and a roller is arranged at this end at one end of the positioning rod away from the sliding groove.

[0004] Although the above-mentioned clamps have improved applicability, most of the hand plates are shells. Without internal structural support, it is easy to cause the clamping position to be concave, which can easily lead to unstable clamping structure and affect the processing accuracy. Summary of the invention

[0005] The purpose of this application is to provide a CNC handboard engraving fixture to address the above-mentioned technical problems, which can improve the stability of the handboard when it is clamped, keep the handboard structure from deformation, and ensure the processing accuracy of the handboard.

[0006] The present application provides a CNC hand plate engraving fixture, including a clamping table, and also including:

[0007] The clamping mechanism is provided with an outer clamping block and an inner clamping block. When the clamping mechanism clamps the hand plate, the outer clamping block abuts against the outer wall of the hand plate, and the inner clamping block abuts against the inner wall of the hand plate;

[0008] The outer mounting seat is placed on the clamping table and corresponds to the outer clamping block;

[0009] The inner mounting seat is placed on the clamping table and corresponds to the inner clamping block;

[0010] The driving cylinder is respectively installed and connected with the outer clamping block and the inner clamping block;

[0011] The adjusting mechanism is respectively disposed between the outer clamping block, the inner clamping block and the driving cylinder, and is used to adjust the distance between the outer clamping block, the inner clamping block and the driving cylinder;

[0012] There are three or more outer clamping blocks and inner clamping blocks, and the driving cylinder is installed and connected with the corresponding outer mounting seat and inner mounting seat.

[0013] When the hand plate is placed on the clamping table, the driving cylinder drives the outer clamping block and the inner clamping block to move and abut against the inner and outer sides of the hand plate, and the positions where the inner and outer sides abut against each other correspond to each other. The outer mounting seat is used to install the outer clamping block and the corresponding driving cylinder, and the inner mounting seat is used to install the inner clamping block and the corresponding driving cylinder. The adjustment mechanism is used to adjust the distance between the outer clamping block, the inner clamping block and the driving cylinder to adapt to different sizes during the continuous modification of the hand plate.

[0014] Furthermore, the outer mounting seat and the inner mounting seat are provided with sliders, and the clamping platform is provided with slide grooves corresponding to the sliders, and the slide grooves are arc-shaped.

[0015] Different hand plates have different structures. The slider moves in the slide groove to adjust the positions of the outer clamping block and the inner clamping block to make them correspond to the side of the hand plate structure, thereby improving the stability of the hand plate clamping. 2-4 bolts are installed on the slider. When the slider moves to the appropriate position, the bolts are tightened to make them abut against the clamping table, thereby fixing the relative position between the slider and the clamping table.

[0016] Furthermore, the outer mounting seat includes:

[0017] The shaft body is movably connected with the outer mounting seat;

[0018] Adjusting worm gear, mounted on the shaft;

[0019] The adjusting worm corresponds to the adjusting worm wheel.

[0020] After determining the position of the slider, the adjusting worm is rotated to rotate the adjusting worm wheel, and the rigid connection between the adjusting worm wheel and the shaft body is adjusted to rotate the shaft body, and the axis of the outer clamping block is adjusted to be perpendicular to the side wall of the hand plate, thereby further improving the stability of the clamping mechanism clamping the hand plate.

[0021] Furthermore, the shaft body is provided with a connecting seat, the sliding block corresponding to the inner mounting seat is provided with a sliding part, and the connecting seat is provided with a sliding rail corresponding to the sliding part.

[0022] The shaft body is connected to the slider of the inner mounting seat through a connecting seat. The slider of the inner mounting seat is circular so that it can rotate when sliding in the slide groove. The sliding part is slidably connected to the slide rail. When the shaft body rotates, the inner mounting seat is moved through the connecting seat. The connecting seat ensures that the axes of the inner clamping block and the outer clamping block are always the same, ensuring that the inner clamping block and the side wall of the hand plate can be perpendicular and improving the adjustment speed. After the inner mounting seat is adjusted, the bolts on the mounting seat are used to abut against the clamping table to fix the relative position between the slider and the clamping table.

[0023] Furthermore, the regulating mechanism comprises:

[0024] An adjustment seat, placed on the adjustment mechanism;

[0025] The adjusting screw is respectively placed between the outer clamping block, the inner clamping block and the adjusting seat;

[0026] An adjusting nut is placed on the adjusting screw;

[0027] The adjusting screw and the adjusting seat are connected via threads, and a gasket is installed between the adjusting nut and the adjusting seat.

[0028] The outer clamping block and the inner clamping block are adjusted through the threaded connection between the screw and the adjustment seat. After the adjustment is completed, the adjustment screw and the adjustment seat are fixed by the adjustment nut and the gasket to improve the structural stability of the adjustment mechanism after the adjustment is completed.

[0029] Furthermore, the adjustment mechanism also includes:

[0030] A spring, which abuts against the adjusting seat;

[0031] The telescopic rod of the driving cylinder extends into the adjusting seat, and the driving cylinder is provided with a limiting portion which abuts against a spring.

[0032] The spring is used to increase the rigid collision between the inner clamping block, the outer clamping block and the hand plate, so as to prevent clamping marks from appearing on the hand plate and protect the appearance of the hand plate. The spring is placed between the limit part and the adjustment seat, and the spring is installed in the adjustment seat.

[0033] The beneficial effects of this application are:

[0034] 1. When the hand plate is placed on the clamping table, the outer clamping block and the inner clamping block are driven by the driving cylinder to move and abut against the inner and outer sides of the hand plate, and the positions where the inner and outer sides abut against each other correspond to each other, so that the hand plate is clamped.

[0035] 2. Different hand plates have different structures. The slider moves in the slide slot, the worm gear and the worm are adjusted, and the inner clamping block and the outer clamping block are connected through the connecting seat so that they can be perpendicular to the side wall of the hand plate when clamped.

[0036] 3. The distance between the outer clamping block, the inner clamping block and the driving cylinder is adjusted through the adjustment mechanism to adapt to the different sizes of the handboard. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The following provides a detailed description of the embodiments of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0046] Embodiment 1:

[0047] like Figure 1-Figure 4 As shown, the embodiment of the present application provides a CNC hand plate engraving fixture, including a clamping table 100, and also including:

[0048] The clamping mechanism 200 is provided with an outer clamping block 210 and an inner clamping block 220. When the clamping mechanism 200 clamps the hand plate, the outer clamping block 210 abuts against the outer wall of the hand plate, and the inner clamping block 220 abuts against the inner wall of the hand plate;

[0049] The outer mounting seat 300 is placed on the clamping platform 100 and corresponds to the outer clamping block 210;

[0050] The inner mounting seat 400 is placed on the clamping platform 100 and corresponds to the inner clamping block 220;

[0051] The driving cylinder 500 is installed and connected with the outer clamping block 210 and the inner clamping block 220 respectively;

[0052] The adjusting mechanism 600 is respectively disposed between the outer clamping block 210, the inner clamping block 220 and the driving cylinder 500, and is used to adjust the distance between the outer clamping block 210, the inner clamping block 220 and the driving cylinder 500;

[0053] There are three or more outer clamping blocks 210 and inner clamping blocks 220 , and the driving cylinder 500 is installed and connected with the corresponding outer mounting seat 300 and inner mounting seat 400 .

[0054] When the hand plate is placed on the clamping table 100, the driving cylinder 500 drives the outer clamping block 210 and the inner clamping block 220 to move and abut against the inner and outer sides of the hand plate, and the positions where the inner and outer sides abut against each other correspond to each other. The outer mounting seat 300 is used to install the outer clamping block 210 and the corresponding driving cylinder 500, and the inner mounting seat 400 is used to install the inner clamping block 220 and the corresponding driving cylinder 500. The adjustment mechanism 600 is used to adjust the distance between the outer clamping block 210, the inner clamping block 220 and the driving cylinder 500 to adapt to different sizes during the continuous modification of the hand plate.

[0056] Different hand plates have different structures. The slider 700 moves in the slide groove 110 to adjust the positions of the outer clamping block 210 and the inner clamping block 220 to make them correspond to the side of the hand plate structure, thereby improving the stability of clamping the hand plate. 2-4 bolts are installed on the slider 700. When the slider 700 moves to the appropriate position, the bolts are tightened to make them abut against the clamping platform 100, thereby fixing the relative position between the slider 700 and the clamping platform 100.

[0057] Furthermore, the outer mounting seat 300 includes:

[0058] The shaft body 310 is movably connected to the outer mounting seat 300;

[0059] An adjusting worm wheel 320 is mounted on the shaft body 310;

[0060] The adjusting worm 330 corresponds to the adjusting worm wheel 320 .

[0061] After determining the position of the slider 700, the worm gear 320 is rotated by adjusting the worm 330, and the rigid connection between the worm gear 320 and the shaft body 310 is adjusted to rotate the shaft body 310, so that the axis of the outer clamping block 210 is adjusted to be perpendicular to the side wall of the hand plate, thereby further improving the stability of the clamping mechanism 200 in clamping the hand plate.

[0062] Furthermore, the shaft body 310 is provided with a connecting seat 340 , the sliding block 700 corresponding to the inner mounting seat 400 is provided with a sliding portion 350 , and the connecting seat 340 is provided with a sliding rail 360 corresponding to the sliding portion 350 .

[0063] The shaft body 310 is connected to the slider 700 of the inner mounting seat 400 through the connecting seat 340. The slider 700 of the inner mounting seat 400 is circular, so that it can rotate when sliding in the slide groove 110. The sliding part 350 is slidably connected to the slide rail 360. When the shaft body 310 rotates, the inner mounting seat 400 is moved through the connecting seat 340. The connecting seat 340 ensures that the axes of the inner clamping block 220 and the outer clamping block 210 are always the same, ensuring that the inner clamping block 220 and the side wall of the hand plate can be perpendicular and improving the adjustment speed. After the inner mounting seat 400 is adjusted, the bolts on the mounting seat are used to abut against the clamping table 100 to fix the relative position between the slider 700 and the clamping table 100.

[0070] The outer clamping block 210 and the inner clamping block 220 are adjusted through the threaded connection between the screw and the adjustment seat 610. After the adjustment is completed, the adjustment screw 620 and the adjustment seat 610 are fixed by the adjustment nut 630 and the gasket to improve the structural stability of the adjustment mechanism 600 after the adjustment is completed.

[0071] Furthermore, the adjustment mechanism 600 further includes:

[0072] The spring 640 abuts against the adjustment seat 610;

[0073] The telescopic rod of the driving cylinder 500 extends into the adjusting seat 610 , and the driving cylinder 500 is provided with a limiting portion 650 that abuts against the spring 640 .

[0074] The spring 640 is used to increase the rigid collision between the inner clamping block 220 and the outer clamping block 210 and the hand plate, thereby preventing clamping marks from appearing on the hand plate and protecting the appearance of the hand plate. The spring 640 is placed between the limit part 650 and the adjustment seat 610, and the spring 640 is installed in the adjustment seat 610.
