DETAILED DESCRIPTION
[0020] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the following will be further described in conjunction with specific embodiments.
[0021] A kind of hard alloy processing auxiliary device, see Figures 1 to 3 , including bottom plate 1, arc-shaped frame 3, sliding frame 8, limiting bolt 401 and screw rod 5, the top end left side edge of bottom plate 1 is fixedly connected with fixed plate 2, the top end of bottom plate 1 front and back both sides are equipped with adjusting groove 101, and the front and back side walls of bottom plate 1 are equipped with constraint groove 102, constraint groove 102 is communicated with adjusting groove 101, the bottom two ends of arc-shaped frame 3 are vertically through adjusting groove 101, and the top end of arc-shaped frame 3 is equipped with moving groove 301, one end of screw rod 5 is through moving groove 301 and is rotatably connected with clamping block 6 by bearing, so that the clamping block 6 at the bottom end of screw rod 5 is pressed against alloy surface and is fixed by using nut on screw rod 5, and clamping can be completed, arc-shaped frame 3 can be freely moved along adjusting groove 101, and screw rod 5 can freely select quantity and position in moving groove 301, so that the angle and position of clamping and fixing can be freely selected.
[0022] It should be noted that the width of screw rod 5 is slightly smaller than moving groove 301, and a fixed nut is threadedly connected to the surface of screw rod 5 on the upper and lower sides of arc-shaped frame 3, after the lower clamping block 6 is pressed against the alloy, the nut can be twisted towards arc-shaped frame 3, so that screw rod 5 is fixed in the upper and lower directions, avoiding free sliding.
[0023] The bottom of the base plate 1 is provided with a sliding groove 7. The top of the slide 8 protrudes and slides laterally on the inner side of the sliding groove 7. The side wall of the slide 8 is provided with a toothed groove 801. A fixing frame 9 is fixedly connected to the right edge of the bottom of the base plate 1 on one side of the toothed groove 801. The inner surface of the fixing frame 9 is rotatably connected to a drive gear 10, and the drive gear 10 meshes with the toothed groove 801. A vertical block 802 is fixedly connected to the right end of the fixing frame 9. A connecting rod 13 is fixedly connected to the side surface of the vertical block 802 facing the base plate 1. A push plate 14 is fixedly connected to the left end of the connecting rod 13. The rotation of the drive gear 10 will drive the slide 8 to move along the sliding groove 7, so that the push plate 14 moves laterally on the surface of the base plate 1, thereby cooperating with the fixing plate 2 to hold the alloy from both ends. With the clamping of the arc-shaped frame 3 and the clamping block 6, the stability of the alloy is further increased.
[0024] Specifically, such as Figure 2 As shown, a protrusion 11 is fixedly connected to the left edge of the side wall of the carriage 8 on the opposite side of the tooth groove 801. A limiting block 12 is fixedly connected to the bottom right edge of the base plate 1 at the horizontal position of the protrusion 11. The limiting block 12 can block the protrusion 11 to prevent the carriage 8 from sliding completely out of the slide groove 7 and falling.
[0025] It is worth noting that, such as Figure 2 As shown, a servo motor 1001 is fixedly connected to the bottom of the fixed frame 9. The output end of the transmission shaft of the servo motor 1001 is fixedly connected to the drive gear 10. After the servo motor 1001 is started, it drives the drive gear 10 to rotate. The drive gear 10 drives the slide 8 to move laterally through the tooth groove 801 to adjust the distance between the fixed plate 2 and the push plate 14.
[0026] It is worth noting that, such as Figure 1 and Figure 3 As shown, threaded holes 4 are provided on both the front and rear side walls of the arc frame 3. The limiting bolt 401 passes laterally through the constraint groove 102 and is threadedly connected to the arc frame 3 through the threaded hole 4. When the height of the arc frame 3 needs to be adjusted, simply align the corresponding threaded hole 4 with the constraint groove 102, and then screw the limiting bolt 401 in to press the arc frame 3 to fix it. The arc frame 3 and the adjustment groove 101 have the same width, so there will be friction when the arc frame 3 is inserted into the adjustment groove 101, which increases stability.
[0027] It is worth noting that, such as Figure 1 As shown, the bottom of the push plate 14 is in contact with the top surface of the base plate 1, and the connecting rod 13 is parallel to the surface of the base plate 1, thereby ensuring that the push plate 14 can be completely perpendicular to the surface of the base plate 1 and maintain the horizontal pushing of the alloy.
[0028] It is worth noting that, such as Figure 1As shown, soft pads 15 are fixedly connected to the surfaces of the fixed plate 2 and the push plate 14 on opposite sides. The soft pads 15 can buffer and protect the fixed plate 2 and the push plate 14 when clamping, so as to prevent the alloy from damaging the fixed plate 2 and the push plate 14.
[0029] In practical use, the alloy is placed on the base plate 1 and pressed against the fixing plate 2. The arc frame 3 is inserted into the adjustment groove 101, and the appropriate threaded hole 4 on the arc frame 3 is selected according to the height of the alloy. The limit bolt 401 is screwed in to fix the arc frame 3. Then, the clamping block 6 at the bottom of the screw 5 is pressed against the surface of the alloy, and the screw 5 is fixed with a nut to complete the clamping. The arc frame 3 can move freely along the adjustment groove 101, and the number and position of the screw 5 can be freely selected in the moving groove 301, so that the clamping angle and position can be freely selected, which improves the adaptability and practicality of the device. The rotation of the drive gear 10 will drive the slide 8 to move along the slide groove 7, so that the push plate 14 moves laterally on the surface of the base plate 1, thereby cooperating with the fixing plate 2 to press against the alloy from both ends. With the clamping of the arc frame 3 and the clamping block 6, the clamping stability is improved.
[0030] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.
