[0002] The tooling fixture base is a basic structural component used to fix and support the parts or fixtures being tested during the testing or production process, and usually serves as the installation platform for the entire tooling system.

[0003] Most tooling fixtures currently in use have low positioning accuracy. Existing equipment may only use simple positioning methods, such as single plane positioning or a few simple positioning pins, which makes it difficult to achieve high-precision positioning. Furthermore, the positioning structure of existing equipment is usually fixed and cannot be flexibly adjusted according to different specifications of fixtures. When it is necessary to test parts of different sizes or shapes, it may be necessary to replace the entire fixture or carry out complex modifications. Utility Model Content

[0004] The purpose of this invention is to provide a component testing fixture base with a quick positioning groove to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a component testing fixture base with a quick positioning groove, comprising a base plate, a V-groove, a vertical insert rod, and an electric cylinder. The top of the base plate has horizontally spaced positioning ribs, and side pads are evenly spaced on both sides of the base plate. A base is positioned directly above the base plate, and a positioning mechanism is provided on the outer side of the base. The positioning mechanism engages and positions the protruding part at the bottom of the fixture via the V-groove on the outer side, and positions and locks the bottom of the fixture around the perimeter via the vertically positioned insert rod. A shifting mechanism is provided inside the base, which adjusts the position of the vertical insert rod according to the fixture specifications and the required positioning position.

[0006] As a preferred technical solution, the positioning mechanism includes a base, a V-groove, a positioning hole, a vertical rod, and a pin. The base has V-grooves on both sides of its top end, and positioning holes are equally spaced in the middle of the base. The vertical rod is connected through the base and is parallel to the positioning hole. The pin is threaded to the outer side of the vertical rod.

[0007] As a preferred technical solution, the substrate is connected to the bottom groove of the base by transverse positioning ribs evenly distributed at the top.

[0008] As a preferred technical solution, the switching mechanism includes a servo cylinder, a tray, a bracket, a slider, a slide rail, and an electric cylinder.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: Figures 1 to 5 As shown, this utility model provides the following technical solution: a component testing fixture base with a quick positioning groove, including a base plate 1, a V-groove 5, a vertical insertion rod 9, and an electric cylinder 16. The top of the base plate 1 is provided with horizontal positioning ribs 2 evenly spaced. Side pads 3 are provided at equal intervals on both sides of the base plate 1. A base 4 is provided directly above the base plate 1. A positioning mechanism 6 is provided on the outer side of the base 4. The positioning mechanism 6 uses the V-groove 5 on the outer side to engage and position the protruding part at the bottom of the fixture, and uses the vertical insertion rod 9 to position and lock the bottom of the fixture around its perimeter. A shifting mechanism 15 is provided inside the base 4. The shifting mechanism 15 adjusts the position of the vertical insertion rod 9 according to the specifications of the fixture and the required positioning position.

[0017] Among them, the transverse positioning ribs 2 evenly distributed at the top of the base plate 1 can play a preliminary coarse positioning role, so that the base 4 can be quickly and roughly placed in the appropriate position, improving the clamping efficiency. The base plate 1 serves as the foundation of the entire fixture base, and the transverse positioning ribs 2 distributed at its top and the side pads 3 set on both sides provide stable support for the fixture.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, the positioning mechanism 6 includes a base 4, a V-groove 5, a positioning hole 7, a vertical insertion rod 9, and a pin rod 10. The base 4 has V-grooves 5 on both sides of its top end, and positioning holes 7 are equally spaced in the middle of the base 4. The vertical insertion rod 9 passes through and is connected to the base 4. The vertical insertion rod 9 and the positioning hole 7 are arranged parallel to each other. The pin rod 10 is threaded to the outer side of the vertical insertion rod 9. The base plate 1 is connected to the bottom groove of the base 4 through horizontal positioning ribs 2 evenly distributed at its top end.

[0019] Among them, the V-shaped grooves 5 opened on both sides of the top of the base 4 can quickly and accurately perform preliminary positioning of the protruding part at the bottom of the fixture. The V-shaped grooves 5 utilize the characteristics of the inclined surfaces on both sides to enable the fixture to automatically center when placed, effectively limiting the movement of the fixture on the horizontal plane. The vertical insertion rods 9 can accurately position and lock the bottom of the fixture from all sides, further limiting the displacement of the fixture in the vertical direction and other directions. Together with the V-shaped grooves 5, high-precision positioning is achieved.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the switching mechanism 15 includes a servo cylinder 8, a support plate 11, a bracket 12, a slider 13, a slide rail 14, and an electric cylinder 16. The servo cylinder 8 is installed on one side of the base 4. The slide rail 14 is provided inside the base 4. The bracket 12 is provided directly above the slide rail 14. The support plate 11 is provided directly above the bracket 12. Vertical rods 9 are rectangularly distributed at the top of the support plate 11. The slider 13 is connected to the output end of the servo cylinder 8. The electric cylinder 16 is provided inside the bracket 12. The bracket 12 is connected to the outside of the slide rail 14 through the slider 13 at its bottom end. The slide rail 14 is parallel to the servo cylinder 8. The vertical rods 9 are connected to the output end of the electric cylinder 16 through the support plate 11 connected at its bottom end.

[0021] The vertical insertion rod 9 passes through the base 4 and is set parallel to the positioning hole 7. The servo cylinder 8 can drive the slider 13 to move along the slide rail 14, realizing the coarse positioning and rapid movement of the bracket 12 and its upper components in the horizontal direction. The electric cylinder 16 can accurately control the position of the tray 11 and the vertical insertion rod 9 in the vertical direction. The two work together to achieve the precise positioning of the vertical insertion rod 9 in the two-dimensional plane, meeting the different requirements of different specifications of fixtures for the position of the vertical insertion rod 9, with high positioning accuracy.

[0022] The working principle of this utility model is as follows: The operator first installs the side pads 3 on the left and right sides of the base plate 1, and then locks the side pads 3 and the ground with fasteners. Then, the horizontal positioning ribs 2, which are equally spaced on the outer side of the base plate 1, are inserted into the bottom groove of the base 4 to reduce the difficulty of installing the base 4 and the base plate 1. The operator then locks the bottom of the base plate 1 and the base 4 with the bottom vertical insertion bolts. Then, the bottom protruding part of the mold is placed directly on the surface of the base 4, and the bottom protruding part of the fixture is placed in the V-groove 5 on both sides of the top of the base 4. The inclined surfaces on both sides of the V-groove 5 contact the bottom protruding part of the fixture. According to the processing part and range of the fixture and the machine tool, the operator moves the fixture laterally on the outside of the base 4 to guide the fixture to the roughly correct position. When the vertical rod 9 needs to be adjusted horizontally, the servo cylinder 8 is activated. The output end of the servo cylinder 8 pushes the slider 13 connected to it to move along the slide rail 14. Since the bracket 12 is installed on the slider 13, the bracket 12, the support plate 11 above it, and the vertical rod 9 will move together with the slider 13. The support plate 11 is threaded with a pin rod 10 on the outside. When the vertical rod 9 is adjusted to the appropriate position; By activating the electric cylinder 16, the support plate 11 and the four sets of vertical rods 9 are moved vertically upwards, allowing the vertical rods 9 to be extended from the inside of the base 4 and inserted through the positioning hole 7. The vertical rods 9 are then inserted into the bottom of the fixture seat, aligning with the four sides of the bottom of the fixture. The vertical rods 9 provide further positioning and constraint for the bottom of the fixture from all sides. Then, by inserting the horizontal pin 10 and tightening the pin 10, the vertical rods 9 and the fixture seat can be fixed on the base 4 to prevent displacement during the test.
