Detailed implementation manner

[0024] In the technical solution of the embodiment of the present application, to solve the problem that the inclined block will become loose and leave the support position during vibration, resulting in support failure, so that the workpiece cannot be accurately clamped and positioned. In this case, the operator needs to re-place the inclined block at the support position, which reduces the production efficiency on the one hand and affects the product quality on the other hand. The general idea is as follows:

[0025] Please refer to Figures 1-6 , a tension spring anti-loosening inclined block auxiliary support mechanism, including a fixture assembly 10 and an auxiliary support assembly 20.

[0026] Among them, under the action of the tension spring 240, the limit bolt 250 and the limit block 260, the inclined support block 210 is prevented from loosening when supporting the workpiece.

[0027] Please refer to Figure 1 , Figure 2 and Figure 3 , the fixture assembly 10 includes a fixture base 110; a support for workpiece positioning.

[0028] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The auxiliary support assembly 20 includes an inclined support block 210, a spring pull rod 220, a pin 230, a tension spring 240, a limiting bolt 250 and a limiting block 260. The spring pull rod 220 and the limiting bolt 250 are respectively installed on the upper surfaces of both ends of the clamp base 110. The inclined support block 210 is located on the clamp base 110. A strip groove 211 is provided at the bottom of the inclined support block 210. Both ends of the pin 230 are respectively arranged on the opposite surfaces of the inner wall of the strip groove 211 close to one end of the limiting bolt 250. Both ends of the tension spring 240 are respectively connected with the spring pull rod 220 and the pin 230. Specifically, one end of the tension spring 240 is hung on the pin 230, a circular through groove is provided on the spring pull rod 220, and the other end of the tension spring 240 is hung on the circular through groove. The tension spring 240 is located inside the strip groove 211, and the two ends of the limit block 260 are respectively fixedly connected to the opposite surfaces of the inner wall of the strip groove 211 below the pin 230. Specifically, the limit block 260 and the oblique support block 210 can be integrally formed, and the bottom ends of the limit block 260 and the oblique support block 210 are on the same horizontal line. Both sides of the limit block 260 are inwardly concave arc shapes, and the two sides are arc-shaped, so that it is more stable when cooperating with the limit bolt 250 for limiting, and the curvature of the two arcs is the same as the curvature of the outer side of the limit bolt 250. When in use, when it is necessary to support the workpiece, hold the inclined support block 210 with one hand, place the inclined support block 210 to one side of the spring pull rod 220, so that the inclined support block 210 is located between the spring pull rod 220 and the limiting bolt 250, and then make the limiting block 260 close to one side of the limiting bolt 250, and under the action of the tension spring 240, make the limiting block 260 and one side of the limiting bolt 250 tightly abut, so that the inclined support block 210 will not loosen due to vibration when supporting the workpiece, and improve the stability of the inclined support block 210 when supporting the workpiece. After the workpiece positioning support is completed, hold the inclined support block 210, lift it upward, so that the limiting block 260 leaves the limiting bolt 250, and then pull it away from the other end of the spring pull rod 220, and make the other side of the limiting block 260 and the other side of the limiting bolt 250 tightly abut under the action of the tension spring 240, so as to prevent the inclined support block 210 from affecting the positioning of the workpiece. The setting of the limiting bolt 250 can prevent the inclined support block 210 from being disengaged from the support position due to vibration during the support process, thereby improving production efficiency. At the same time, when not in use, the inclined support block 210 can be moved without interfering with the positioning of the workpiece, which is stable and effective. The operation process of the entire device is simple and convenient, which is conducive to promotion.

[0029] A first arc-shaped anti-skid pad 270 is attached to one side of the limit block 260. Specifically, the curvature of the bottom end of the first arc-shaped anti-skid pad 270 is the same as the curvature of the outer side of the limit bolt 250, and is made of rubber material with good anti-skid performance. The first arc-shaped anti-skid pad 270 makes the tight contact between the limit block 260 and the limit bolt 250 more stable when the oblique support block 210 is supported.

[0030] A second arc-shaped anti-skid pad 280 is attached to the other side of the limit block 260. Specifically, the curvature of the second arc-shaped anti-skid pad 280 is the same as the curvature of the outer side of the limit bolt 250, and is made of rubber material with good anti-skid performance. The second arc-shaped anti-skid pad 280 makes the tight contact between the limit block 260 and the limit bolt 250 more stable when the oblique support block 210 leaves the support point.

[0031] A threaded hole is provided at one end of the clamp base 110, and the limiting bolt 250 is threadedly connected to the clamp base 110 through the threaded hole. The limiting bolt 250 is rotated inside the threaded hole to achieve fixation with the clamp base 110.

A magnet 120 is fixed to the bottom end of the spring pull rod 220, and a magnet block 130 matching the magnet 120 is provided on the inner bottom wall of the placement groove 111. A first fixed groove is provided at the bottom end of the spring pull rod 220, and the magnet 120 is provided in the first fixed groove. A second fixed groove is provided on the inner bottom wall of the placement groove 111 of the clamp base 110, and the magnet block 130 is provided in the second fixed groove. Among them, the spring pull rod 220 is provided on the clamp base 110 through the cooperation between the magnet 120 and the magnet block 130, and can be disassembled at the same time.

[0033] When the present application is used: When the workpiece needs to be supported, hold the inclined support block 210 with one hand, place the inclined support block 210 to one side of the spring pull rod 220, so that the inclined support block 210 is located between the spring pull rod 220 and the limiting bolt 250, and then make the limiting block 260 close to one side of the limiting bolt 250, and under the action of the tension spring 240, make the limiting block 260 and one side of the limiting bolt 250 tightly abut, so that the inclined support block 210 will not loosen due to vibration when supporting the workpiece, and improve the stability of the inclined support block 210 when supporting the workpiece. After the workpiece positioning support is completed, hold the inclined support block 210, lift it upward, so that the limiting block 260 leaves the limiting bolt 250, and then pull it away from the other end of the spring pull rod 220, and make the other side of the limiting block 260 and the other side of the limiting bolt 250 tightly abut under the action of the tension spring 240, so as to prevent the inclined support block 210 from affecting the positioning of the workpiece. The setting of the limiting bolt 250 can prevent the inclined support block 210 from being disengaged from the support position due to vibration during the support process, thereby improving production efficiency. At the same time, when not in use, the inclined support block 210 can be moved without interfering with the positioning of the workpiece, which is stable and effective. The operation process of the entire device is simple and convenient, which is conducive to promotion.

[0034] In summary, the present application utilizes the setting of the limiting bolt 250 to prevent the inclined support block 210 from being disengaged from the support position due to vibration during the support process, thereby improving production efficiency.
