Description

Technical Field

[0001] The utility model mainly relates to the technical field of sorting machines, and in particular to a positioning jig for a sorting machine. Background Art

[0002] Sorting is a key process in industries such as logistics and manufacturing. With the increasing variety of products and the continuous expansion of production scale, the requirements for sorting efficiency and accuracy are becoming increasingly higher.

[0003] Traditional sorting methods have many problems when handling workpieces. In terms of positioning, many sorting systems rely on simple mechanical limits or manual visual alignment, and lack precise positioning mechanisms. For workpieces with complex shapes and varying sizes, this rough positioning method can easily lead to large positioning errors. In the clamping and fixing process, traditional methods may use a single clamping method, such as a simple clamp or a pressure block, which cannot adapt well to workpieces of different shapes and sizes. For some fragile or surface-sensitive workpieces, improper clamping force may cause damage to the workpiece. Moreover, the clamping stability is also poor, and the workpiece may be displaced during the sorting process, resulting in sorting errors.

[0004] Furthermore, traditional sorting and positioning devices lack flexibility and adaptability. When a new type of workpiece needs to be sorted, the entire sorting equipment often needs to be extensively remodeled or replaced with new positioning fixtures, which increases production costs and equipment upgrade time.

[0016] The clamping mechanism of the present invention adopts a structure in which a double-headed screw drives two clamping blocks, which can achieve a stable and reliable clamping effect. The rotation of the double-headed screw can accurately control the movement distance of the clamping block, ensuring that the appropriate clamping force is applied to the workpiece.

Especially for some workpieces with high surface accuracy requirements or fragile workpieces, this protective measure can ensure the integrity of the workpiece and improve the sorting yield rate. The present invention has good stability. The clamping mechanism drives the movement of the clamping block through the double-headed screw, which can adapt to workpieces of different widths or diameters. By adjusting the rotation direction and number of turns of the motor, the distance between the clamping blocks can be controlled, thereby clamping workpieces of different sizes, expanding the scope of application of the positioning fixture.

A positioning block 5 and a clamping mechanism 6 are provided on the Y-axis moving plate 4. The clamping mechanism 6 is provided below the positioning block 5. The positioning block 5 is used to position the workpiece 7, and the clamping mechanism 6 is used to fix the workpiece 7. Figure 2 As shown, the workpiece in this embodiment is annular.

[0029] The position adjustment mechanism 3 includes an electric push rod 31 fixed on the X-axis moving plate 2, a slider 32 fixedly installed on the Y-axis moving plate 4, a slide rail 33 fixedly installed on the X-axis moving plate 2, the slider 32 is slidably installed on the slide rail 33, and a limit block 34 is also provided on the X-axis moving plate 2.

[0030] The positioning block 5 is fixed on the Y-axis moving plate 4 through a plurality of support columns 51 . A positioning groove 52 for placing the workpiece 7 is formed on the positioning block 5 .

[0031] The clamping mechanism 6 includes two bearing seats 61 fixed on the Y-axis movable plate 4, and a double-headed screw 62 is rotatably installed between the two bearing seats 61. Two clamping blocks 63 are threadedly installed on the double-headed screw 62. The rotation of the double-headed screw 62 drives the two clamping blocks 63 to move relatively closer or relatively farther away.

[0032] A guide groove 64 is provided on the Y-axis moving plate 4 , a guide block matching the guide groove 64 is provided on the clamping block 63 , one end of the double-headed screw 62 is connected to the motor 66 , and an anti-collision pad 65 is provided on the clamping block 63 .

[0033] Working principle:

[0034] First, the sorting machine transports the workpiece 7 to be sorted to the vicinity of the positioning fixture. At this time, the linear module 1, the electric push rod 31 and the motor 66 and other driving components are in the initial state.

[0035] According to the preset program or sensor feedback, the linear module 1 starts, driving the X-axis movable plate 2 to move along the X-axis direction. This action is to make the positioning fixture close to the workpiece 7 in the horizontal X-axis direction, so that subsequent positioning and clamping operations can be carried out accurately. Then, the electric push rod 31 in the position adjustment mechanism 3 works to push the Y-axis movable plate 4 to move along the Y-axis direction. The Y-axis movable plate 4 slides on the slide rail 33 on the X-axis movable plate 2 through the slider 32. The limit block 34 can limit the moving range of the Y-axis movable plate 4 to ensure that it moves within the predetermined stroke. Through movement in the X-axis and Y-axis directions, the positioning block 5 and the clamping mechanism 6 are brought close to the workpiece 7. Ensure that the positioning block 5 and the clamping mechanism 6 are accurately aligned with the workpiece in the X-axis and Y-axis directions to achieve precise positioning in the two-dimensional plane.

[0036] When the positioning jig approaches workpiece 7, it is placed into positioning groove 52 on positioning block 5. The shape and size of positioning groove 52 match workpiece 7, accurately determining its position and ensuring its positional accuracy during subsequent operations. Using positioning groove 52 on positioning block 5 to precisely position workpiece 7 is a key step in ensuring sorting accuracy. The matching design of positioning groove 52 and workpiece 7 eliminates in-plane positional deviations of workpiece 7, ensuring that subsequent clamping and sorting operations are based on an accurate positional reference.

[0037] Start the motor 66 of the clamping mechanism 6, and the motor 66 drives the double-headed screw 62 to rotate. Since two clamping blocks 63 are installed on the double-headed screw 62 through threads, and the clamping blocks 63 cooperate with the guide groove 64 on the Y-axis moving plate 4 through the guide block, when the double-headed screw 62 rotates, the two clamping blocks 63 will be relatively close to each other along the guide groove 64. The anti-collision pad 65 on the clamping block 63 can prevent damage to the workpiece 7 during the clamping process. The two clamping blocks 63 gradually clamp the workpiece 7 and fix it firmly on the positioning block 5. Stable clamping can ensure that the workpiece always remains in the correct position when the sorting machine moves or operates the workpiece, avoiding sorting errors caused by shaking or movement of the workpiece 7.

[0038] After workpiece 7 is accurately positioned and clamped, the sorting machine can accurately sort it to the designated location based on the workpiece 7's position information on the positioning fixture, completing the sorting task. Once sorting is complete, motor 66 reverses, and the double-headed screw 62 drives the two clamping blocks 63 away from each other, releasing workpiece 7. The electric push rod 31 and linear module 1 then respectively drive the Y-axis moving plate 4 and X-axis moving plate 2 back to their initial positions, preparing for the next sorting operation.

[0039] The above-mentioned embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, which all fall within the scope of protection of the utility model. Therefore, the scope of protection of the utility model patent shall be based on the attached claims.
