[0006] As a further improvement of the present technical solution, the correction mechanism includes a central groove opened at the bottom of the positioning groove, a pressure block is slidingly provided on the inner wall of the central groove, the lower surface of the protrusion is squeezed and fitted with the upper surface of the pressure block, the protrusion presses the pressure block downward, and a spring is fixedly connected between the lower surface of the pressure block and the bottom surface of the central groove, and the spring pushes the pressure block upward.

[0007] As a further improvement of the present technical solution, a plurality of movable grooves are provided in the annular array on the top of the jig, and a limiting rod is provided near the top of the movable groove. The lower end of the limiting rod is hinged with a connecting rod, and one end of the connecting rod is hinged to the side wall of the pressure block.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] See also Figure 1 、 Figure 2 and Figure 3 As shown, this embodiment provides a product angle positioning device, including a jig 1, a product body 4 is provided on the upper surface of the jig 1, a positioning groove 2 is opened on the top of the jig 1, a proximity switch 3 is fixedly connected to the top of the jig 1, the proximity switch 3 is electrically connected to the product processing equipment, and a protrusion 42 is fixedly connected to the bottom of the product body 4. The product body 4 is a disc-shaped object, and the protrusion 42 consists of a cylinder concentrically arranged with the product body 4 and four long blocks. The long blocks are fixed in an annular array on the outer wall of the cylinder. The shapes of the positioning groove 2 and the protrusion 42 are adapted. When the product body 4 is placed on the jig 1, the protrusion 42 is slidably set inside the positioning groove 2, and the protrusion 42 and the positioning groove 2 are engaged to limit the rotation of the product body 4. A mold stamp 41 is opened at the bottom of the product body 4. Figure 4 The mold mark 41 is set directly above the proximity switch 3. After the proximity switch 3 senses the mold mark 41, the processing equipment starts normally. When the product body 4 is placed in the wrong direction on the jig 1, the mold mark 41 is not directly above the proximity switch 3, and the proximity switch 3 cannot sense the mold mark 41. At this time, the proximity switch 3 will send an electrical signal to the processing equipment, causing the processing equipment to alarm and prevent the processing equipment from starting, thereby preventing the product body 4 from having a bad angle after being placed in the wrong position. A correction mechanism 5 is provided on the jig 1, which clamps and limits the horizontal movement of the product body 4, and aligns and corrects the product body 4 when clamping and limiting, and clamps and fixes the product body 4 at a predetermined position on the jig 1, so that the processing equipment can accurately process the product body 4.

[0026] When the protrusion 42 is placed in the positioning groove 2, there is a gap between the protrusion 42 and the inner wall of the positioning groove 2, so as to facilitate the insertion of the protrusion 42 into the positioning groove 2. However, due to the gap between the protrusion 42 and the positioning groove 2, when the protrusion 42 and the positioning groove 2 are engaged to restrict the rotation of the product body 4, there is still a certain amount of activity space for the protrusion 42 inside the positioning groove 2. There is a possibility that the position of the product body 4 on the upper surface of the jig 1 deviates from the predetermined processing position. In order to align and correct the product body 4 to the predetermined processing position, the structure of the correction mechanism 5 is detailed below. Figure 5 and Figure 6 The correction mechanism 5 includes a central groove 51 provided at the bottom of the positioning groove 2. A pressure block 52 is slidingly provided on the inner wall of the central groove 51. When the protrusion 42 is placed inside the positioning groove 2, the protrusion 42 presses the pressure block 52 downward. A spring 53 is fixedly connected between the lower surface of the pressure block 52 and the inner bottom surface of the central groove 51. The spring 53 pushes the pressure block 52 upward. When the pressure block 52 is pressed downward, the spring 53 is in an elastic contraction state.

[0027] A plurality of movable grooves 54 are provided in a circular array on the top of the fixture 1. A limit rod 55 is provided near the top of the movable groove 54. The limit rod 55 is an inverted T-shaped structure. The inner wall of the movable groove 54 is symmetrically provided with guide grooves. The two ends of the horizontal section of the limit rod 55 are respectively slidably provided inside the two guide grooves, so that the limit rod 55 can only move horizontally along the inner wall of the movable groove 54. The lower end of the limit rod 55 is hinged with a connecting rod 56. One end of the connecting rod 56 is hinged to the side wall of the pressure block 52. The connecting rod 56 is arranged at an angle, and the pressed pressure block 52 drives one end of the connecting rod 56 When moving downward, the connecting rod 56 will flip over, and the other end of the connecting rod 56 will drive the limiting rod 55 to move horizontally toward the product body 4. When the protrusion 42 presses the upper surface of the pressure block 52 to a position on the same horizontal plane as the inner bottom surface of the positioning groove 2, several limiting rods 55 are squeezed and matched with the side walls of the product body 4, so that the jig 1 cannot move horizontally, thereby limiting the position of the product body 4 on the jig 1. At this time, the position of the product body 4 on the jig 1 is the predetermined processing position, so that the processing equipment can accurately process the product body 4.

[0028] When the processing equipment is grooving the product body 4, there is a certain static friction at the contact position between the processing equipment and the product body 4. Therefore, when the processing equipment moves upward, the product body 4 may be driven to move upward under the action of the static friction. In order to avoid the processing equipment driving the product body 4 to move upward and affecting the accuracy of the processed product body 4, the upper end of the limit rod 55 is fixedly connected to a wedge block 57. The side of the wedge block 57 close to the product body 4 is set to an inclined surface. When the limit rod 55 is squeezed and matched with the side wall of the product body 4, the lower end of the inclined surface of the wedge block 57 squeezes the upper end of the side wall of the product body 4 The wedge block 57 acts as a barrier to the product body 4, so that the processing equipment will not drive the product body 4 to move upward, thereby ensuring the processing accuracy of the product body 4. When the worker manually removes the product body 4 from the jig 1, the side wall of the product body 4 squeezes the inclined surface of the wedge block 57, and the squeezed wedge block 57 drives the limit rod 55 to move away from the product body 4, thereby releasing the clamping fixation of the limit rod 55 on the product body 4. At the same time, the limit rod 55 drives the pressure block 52 to move vertically upward through the connecting rod 56, and the spring 53 rebounds to push the pressure block 52 upward, making the pressure block 52 convenient for subsequent use.

[0029] In summary, the working principle of this scheme is as follows: insert the raised portion 42 at the bottom of the product body 4 into the positioning groove 2 on the jig 1, so that the lower surface of the raised portion 42 contacts the upper surface of the pressure block 52, and then release the product body 4. Under the action of its own gravity, the product body 4 presses the pressure block 52 downward, causing the spring 53 to elastically contract, and the pressure block 52 drives one end of the connecting rod 56 to move downward synchronously, so that the other end of the connecting rod 56 drives the limiting rod 55 to move along the inner wall of the movable groove 54 toward the direction close to the product body 4. When the lower surface of the raised portion 42 contacts the bottom surface of the positioning groove 2, several limiting rods 55 all contact the outer wall of the product body 4. After the position of the product body 4 is corrected, it is clamped and fixed, and the product body 4 is adjusted to the predetermined processing position, so that the processing equipment can accurately process the product body 4.
