[0002] In automated production and assembly processes, fixture positioning mechanisms play a vital role. They ensure that workpieces or components can be accurately and quickly positioned in the predetermined position, thereby improving production efficiency and product quality.

[0003] However, traditional fixture positioning mechanisms often suffer from inaccurate positioning, complex operation, and difficulty adjusting. Specifically, traditional fixture positioning mechanisms may rely on simple mechanical structures, such as directly fixing the fixture to the baseplate with bolts or pins. While this method is simple, positioning accuracy is often limited by human error and adjustment is very cumbersome. Alternatively, fixture positioning requires more complex positioning devices, which are complex and costly. Utility Model Content

[0004] One purpose of the utility model is to provide a fixture positioning mechanism to solve the technical problems of the fixture positioning mechanism in the prior art that the structure is complex and the positioning accuracy is low.

[0005] Another purpose of the present invention is to simplify the debugging operation of the fixture positioning mechanism.

[0006] According to the purpose of the present invention, the present invention provides a fixture positioning mechanism, comprising:

[0007] a positioning block, located on the top surface of the substrate, the positioning block having a positioning protrusion extending along a first horizontal direction;

[0008] an auxiliary component located above the base plate, the auxiliary component including at least one positioning pin, the positioning pin being arranged to correspond one-to-one with the positioning hole of the jig, and the auxiliary component being arranged to be movable in a vertical direction, the auxiliary component having a first position in which the positioning pin is positioned in cooperation with the positioning hole and a second position in which the positioning pin is away from the positioning hole;

[0009] An adjustment component is partially installed in the base plate of the fixture, and the adjustment component is located at an end of the base plate away from the positioning block. The adjustment component is configured to drive the base plate to move along the first horizontal direction toward the positioning block, so that when the base plate moves until its positioning groove abuts against the positioning protrusion, the auxiliary component moves to the first position.

[0010] Optionally, the bottom plate is further provided with a positioning column, and the fixture positioning mechanism further comprises:

[0011] At least one toggle clamp is provided in one-to-one correspondence with the positioning block, and the toggle clamp is fixedly installed on the top of the positioning block. The toggle clamp has a clamping state for clamping the positioning column and a releasing state for releasing the positioning column.

[0012] Optionally, the adjustment component includes:

[0013] an adjusting rod, partially disposed within the base plate;

[0014] The handle end is located at an end of the adjusting rod away from the base plate, and the handle end is configured to drive the adjusting rod to drive the base plate to move toward or away from the positioning block when rotating.

[0015] Optionally, the adjusting component is an adjusting screw.

[0016] Optionally, there are two positioning blocks, and the two positioning blocks are symmetrically arranged about the center line of the base plate.

[0019] At least one connecting member is arranged in a one-to-one correspondence with the positioning pins, and the connecting member is configured to protrude from the side surface of the auxiliary component along the first horizontal direction.

[0020] The jig positioning mechanism of the present invention drives the jig to move along the first horizontal direction toward one side of the positioning block by adjusting the adjustment component until the positioning groove of the jig base plate abuts against the positioning protrusion of the positioning block. At this time, the positioning pin of the auxiliary component corresponds to the positioning hole on the fixed plate, and the auxiliary component is moved down to the first position where the positioning pin and the positioning hole are installed to fix the jig in the jig positioning mechanism, thereby realizing precise positioning of the jig positioning mechanism. The structure is simple and the operation is easy.

[0021] Furthermore, the jig positioning mechanism of the present invention also includes at least one toggle clamp arranged in a one-to-one correspondence with the positioning block, and the toggle clamp is fixedly installed on the top of the positioning block. The toggle clamp has a clamping state for clamping the positioning column and a release state for loosening the positioning column, that is, the toggle clamp has two states, clamping and releasing, and the positioning mechanism of the jig can be flexibly adjusted as needed. That is, after the jig positioning is completed, the next jig can be replaced only by adjusting the toggle clamp to the release state, and when positioning the next jig, there is no need to debug the positioning block again, thereby improving production efficiency.

[0033] Figure 1 This is a schematic structural diagram of a fixture positioning mechanism according to an embodiment of the present invention. Figure 2 yes Figure 1 A schematic partial enlarged view of point A is shown. Figure 3 It is a schematic structural diagram of a fixture positioning mechanism from another angle according to an embodiment of the present invention.

[0034] like Figure 1 As shown, the present invention provides a fixture positioning mechanism 100, which includes a positioning block 10, an auxiliary component 20, and an adjustment component 30. The positioning block 10 is located on the top surface of the substrate, and the positioning block 10 has a positioning protrusion 11 extending along the first horizontal direction. The auxiliary component 20 is located above the substrate, and the auxiliary component 20 includes at least one positioning pin 21 (refer to Figure 2 ), the positioning pins 21 are arranged to correspond to the positioning holes 211 of the fixture 200 (refer to Figure 2 ), and the auxiliary component 20 is configured to be movable in the vertical direction, the auxiliary component 20 having a first position in which the positioning pin 21 cooperates with the positioning hole 211 for positioning and a second position in which the positioning pin 21 is away from the positioning hole 211, the adjustment component 30 is partially installed in the base plate 220 of the jig 200, the adjustment component 30 is located at the end of the base plate away from the positioning block 10, and the adjustment component 30 is configured to drive the base plate 220 to move toward the positioning block 10 along the first horizontal direction, so that when the base plate 220 moves until its positioning groove 221 abuts against the positioning protrusion 11, the auxiliary component 20 moves to the first position. Here, the jig 200 includes a fixed plate 210 and a support plate 230, the support plate 230 is fixedly installed above the fixed plate 210, and the support plate 230 is formed with a mounting groove for mounting the auxiliary component 20. Here, the number of the positioning pins 21 can be one or more, and the number of the positioning holes 211 can be one or more.

[0035] In this embodiment, the adjusting component 30 is adjusted to drive the jig 200 to move along the first horizontal direction toward the side of the positioning block 10 until the positioning groove 221 of the bottom plate 220 of the jig 200 abuts against the positioning protrusion 11 of the positioning block 10. At this time, the positioning pin 21 of the auxiliary component 20 corresponds to the positioning hole 211 on the fixed plate 210, and the auxiliary component 20 is moved down to the first position where the positioning pin 21 and the positioning hole 211 are installed in cooperation, so that the jig 200 is fixedly installed in the jig positioning mechanism 100, thereby realizing precise positioning of the jig positioning mechanism 100, with a simple structure and easy operation.

[0036] In this embodiment, the jig positioning mechanism 100 is arranged on the top of the substrate, and the substrate includes a plurality of spaced-apart limit members, which are distributed on both sides of the substrate along a first horizontal direction. The limit members are used to position the jig 200 to ensure that the jig 200 does not deviate from the track when the adjustment component 30 drives the bottom plate 220 of the jig 200 to move toward the positioning block 10, thereby further improving the positioning accuracy of the positioning structure of the jig 200.

[0037] In this embodiment, after the positioning pins 21 of the auxiliary component 20 are fitted into the positioning holes 211 of the fixing plate 210 , the positioning block 10 is fixedly mounted on the base plate to prevent the positioning block 10 from shifting when the fixture 200 is tested or fixed.

[0038] like Figure 3As shown, in a further embodiment, the base plate 220 is further provided with a positioning post 222, and the jig positioning mechanism 100 further includes at least one toggle clamp 40 corresponding to the positioning block 10. The toggle clamp 40 is fixedly mounted on the top of the positioning block 10 and has a clamping state for clamping the positioning post 222 and a released state for releasing the positioning post 222. In this embodiment, the toggle clamp 40 can precisely clamp the positioning post 222, ensuring the stability and accuracy of the jig 200 during operation. Specifically, the clamping state of the toggle clamp 40 ensures that the relative position between the positioning post 222 and the base plate 220 remains unchanged, thereby achieving precise positioning of the workpiece or product. Furthermore, the toggle clamp 40 has two states: clamping and releasing. This allows the positioning mechanism of the jig 200 to be flexibly adjusted as needed. Specifically, after the jig 200 is positioned, the next jig 200 can be replaced simply by adjusting the toggle clamp 40 to the released state. When positioning the next jig 200, there is no need to re-adjust the positioning block 10, thereby improving production efficiency and helping to reduce rework and waste caused by inaccurate positioning, further enhancing overall production efficiency. Furthermore, as a mechanical clamping device, the toggle clamp 40 possesses high strength, durability, and versatility. Through reasonable design and the selection of high-quality toggle clamps 40, the jig 200 can maintain stable performance during long-term use, extending its service life. Furthermore, the toggle clamp 40 can adapt to workpieces of varying shapes and sizes, achieving precise positioning and clamping of various workpiece types, thereby increasing the applicability and flexibility of the jig positioning mechanism 100.

[0039] like Figure 1 As shown, in a further embodiment, the adjustment assembly 30 includes an adjustment rod 31 and a handle end 32. The adjustment rod 31 is partially disposed within the mounting hole, and the handle end 32 is located at the end of the adjustment rod 31 away from the base plate 220. The handle end 32 is configured to rotate to drive the adjustment rod 31 to drive the base plate 220 toward or away from the positioning block 10. In this embodiment, the movement of the base plate 220 is controlled by rotating the handle end 32 without requiring complex operating steps or tools. The rotation of the handle end 32 can achieve slight movement of the base plate 220, thereby improving the positioning accuracy of the fixture positioning mechanism 100. In addition, the structure of the adjustment assembly 30 is compact, resulting in a smaller footprint for the entire fixture positioning mechanism 100. At the same time, the rotation of the handle end 32 can be efficiently converted into movement of the base plate 220, reducing energy loss and transmission error. The tight and reliable connection between the handle end 32 and the adjustment rod 31, and between the adjustment rod 31 and the base plate 220, ensures transmission stability and reliability.

[0040] In a further embodiment, the adjustment component 30 is an adjustment screw. In this embodiment, the adjustment component 30 is an adjustment screw, but it can also be an adjustment nut, an adjustment spring, or an adjustment worm gear mechanism, so that the position of the fixture 200 can be slightly adjusted by rotation, thereby achieving the purpose of precise positioning while ensuring accuracy and stability during processing or operation.

[0041] In a further embodiment, there are two positioning blocks 10, and the two positioning blocks 10 are symmetrically arranged about the center line of the base plate 220. In this embodiment, the two positioning blocks 10 are symmetrically arranged about the center line of the base plate 220, that is, there are two positioning grooves 221 of the base plate 220, and the two positioning grooves 221 are symmetrically arranged about the center line of the base plate 220, so as to ensure that the position of the jig 200 moving toward the positioning blocks 10 in the first horizontal direction is more accurate, that is, the two positioning grooves 221 are positioned respectively by the two positioning blocks 10, and when the positioning grooves 221 move to abut against the ends of the positioning protrusions 11, the positioning protrusions 11 play a guiding role in the movement of the base plate 220, which can further improve the positioning stability of the jig positioning mechanism 100, reduce positioning errors, and improve the positioning accuracy of the jig positioning mechanism 100.

[0042] In a further embodiment, there are two locating pins 21, symmetrically arranged about the centerline of the auxiliary assembly 20. In this embodiment, the symmetrical arrangement of the locating pins 21 provides a more balanced support force, helping to prevent the connected components from tilting or shifting during force application. Furthermore, the locating pins 21 can quickly locate the corresponding locating holes 211 and complete positioning, making the positioning process faster and more accurate, reducing assembly difficulty and improving assembly efficiency. Furthermore, the symmetrical arrangement of the two locating pins 21 prevents over- or under-positioning, thereby ensuring accurate positioning.

[0043] like Figure 2 As shown, in a further embodiment, the auxiliary component 20 also includes at least one connector 22 arranged in a one-to-one correspondence with the locating pin 21, and the connector 22 is configured to protrude from the side of the auxiliary component 20 along the first horizontal direction. In this embodiment, the connector 22 is configured to protrude from the side of the auxiliary component 20 along the first horizontal direction, and the side of the connector 22 away from the main body of the auxiliary component 20 is provided with a mounting hole for fixing the locating pin 21. That is, the connector 22 protrudes in the horizontal direction, which can form an effective anti-torsion structure, enhance the stability of the auxiliary component 20 when subjected to torque, and help prevent damage to the connector 22 or fall-off of the locating pin 21 due to excessive torque. In addition, the protruding design of the connector 22 makes it easier for the locating pin 21 to find the corresponding hole during assembly, thereby simplifying the assembly process and further improving the accuracy and efficiency of assembly.

[0044] The working principle of the jig positioning mechanism 100 in this embodiment is as follows: first, the adjustment component 30 is installed on the base plate 220 of the jig 200, and the adjustment component 30 is adjusted to drive the jig 200 to move toward the positioning block 10, and when the positioning groove 221 of the base plate 220 abuts the positioning protrusion 11 of the positioning block 10, the positioning pin 21 of the auxiliary component 20 is installed in cooperation with the positioning hole 211 on the fixed plate 210 of the jig 200, and the positioning block 10 is fixedly installed on the base plate to achieve the initial positioning of the jig 200 by the jig positioning mechanism 100, and then the elbow clamp 40 above the positioning block 10 is moved to a clamping state so that the elbow clamp 40 clamps the positioning column 222 of the base plate 220, thereby achieving further positioning of the jig 200 by the jig positioning mechanism 100.

[0045] In this embodiment, when replacing the jig 200 to be positioned of the jig positioning mechanism 100, first adjust the elbow clamp 40 from the clamping state to the released state, remove the auxiliary component 20 from the mounting groove of the support plate 230 of the jig 200 to move the positioning pin 21 out of the positioning hole 211, remove the jig 200 to be tested, and move the new jig 200 to the positioning block 10 and sequentially cooperate with the positioning pin 21 and the positioning hole 211 and adjust the elbow clamp 40 to the clamping state to fix the jig 200.

[0046] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
