Apparently, the described embodiments are part of the embodiments of the present invention, rather than all of them. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0040] The following will be combined with Figures 1 to 6 Describe the tooling fixture of the embodiments of the present invention.

[0041] As shown in Figure 1 , Figure 2 and Figure 3 shown, the tooling fixture provided by the embodiment of the present invention includes: a base 1, a limiting component 2, and a positioning mechanism 3; the limiting component 2 is arranged on one side of the base 1; the positioning mechanism 3 includes a positioning component 31 and a locking component 32, the positioning component 31 is arranged at an interval from the limiting component 2, the positioning component 31 is configured with a positioning groove 3111, and the groove wall surface of the positioning groove 3111 and the limiting component 2 are used to abut against the circumferential surface of the workpiece 4 to clamp the workpiece 4; the locking component 32 is connected to the side of the positioning component 31 away from the limiting component 2, the locking component 32 is movably arranged on the base 1, the locking component 32 is used to drive the positioning component 31 to move closer to or away from the limiting component 2, and the locking component 32 is fixed to the base 1 in the locked state.

[0042] Specifically, the tooling fixture includes a base 1, a limiting component 2, and a positioning mechanism 3, and both the limiting component 2 and the positioning mechanism 3 are installed on the base 1. The structure of the base 1 is not specifically limited. For example, the base 1 includes a substrate 11 and a support member 12. A plurality of support members 12 are arranged at intervals along the circumference of the substrate 11. The plurality of support members 12 are used to support the substrate 11. The substrate 11 is used to install the limiting component 2 and the positioning mechanism 3. At the same time, the substrate 11 is also a working platform for clamping the workpiece 4 and performing operations such as assembling, detecting, or repairing the workpiece 4.

[0043] The limiting component 2 and the positioning mechanism 3 are arranged diagonally at both ends of the substrate 11. Along the length direction of the substrate 11, the two opposite ends of the substrate 11 are defined as the first end and the second end of the substrate 11 respectively. The substrate 11 has opposite first and second sides. The upper side of the substrate 11 is the first side along the vertical direction, and the lower side of the substrate 11 is the second side. The limiting component 2 is installed on the first side of the substrate 11, and the limiting component 2 is located at the first end of the substrate 11. The positioning mechanism 3 is located at the second end of the substrate 11. The limiting component 2 is not specifically limited. For example, the limiting component 2 includes two limiting blocks. The two limiting blocks are arranged perpendicular to each other. The two limiting blocks enclose an open limiting area. The limiting area is opposite to the positioning mechanism 3. The inner side surfaces of the two limiting blocks facing the positioning mechanism 3 constitute a limiting portion. The limiting portion can abut against at least two parts of the circumferential surface of the workpiece 4. The workpiece 4 to be clamped is placed on the substrate 11, and the two limiting blocks respectively abut against two parts of the circumferential surface of the workpiece 4. For example, the workpiece 4 is a regular cube, and the two limiting blocks respectively abut against the first side surface and the second side surface that are sequentially connected to the workpiece 4.

[0044] The positioning mechanism 3 includes a positioning component 31 and a locking component 32. One side of the positioning component 31 away from the limiting component 2 is connected to the locking component 32. The positioning component 31 is located above the substrate 11. The locking component 32 is movably connected to the substrate 11. The locking component 32 can reciprocate between the first end and the second end of the substrate 11, and the locking component 32 can drive the positioning component 31 to reciprocate between the first end and the second end of the substrate 11. The locking component 32 has a locking state and an unlocking state. In the unlocking state, the locking component 32 can move relative to the substrate 11 in a first direction, and the first direction is consistent with the length direction of the substrate 11. In the locking state, the locking component 32 is fixed on the substrate 11. The positioning component 31 is provided with a positioning groove 3111, and the groove wall surface of the positioning groove 3111 is used to abut against at least two parts of the circumferential surface of the workpiece 4.

[0045] The use of the fixture is described in detail below. The locking component 32 is in the unlocking state. The locking component 32 drives the positioning component 31 to move from the first end of the substrate 11 towards the second end of the substrate 11 until the area between the limiting component 2 and the positioning component 31 can accommodate the workpiece 4. At this time, the workpiece 4 is placed on the substrate 11, and the workpiece 4 is pressed against the limiting part of the limiting component 2, and the limiting part abuts against two parts of the circumferential surface of the workpiece 4. The locking component 32 drives the positioning component 31 to move from the second end of the substrate 11 towards the first end of the substrate 11, and the positioning groove 3111 gradually approaches the workpiece 4 until the groove wall surface of the positioning groove 3111 abuts against two parts of the circumferential surface of the workpiece 4. The locking component 32 is continuously moved to make the limiting part of the limiting component 2 press against the circumferential surface of the workpiece 4, and the groove wall surface of the positioning groove 3111 press against the circumferential surface of the workpiece 4. At this time, the locking component 32 is adjusted to the locking state, and the locking component 32 is fixed to the substrate 11. Thus, the workpiece 4 is clamped diagonally by the limiting component 2 and the positioning component 31, and the clamping of the workpiece 4 is firm. After the workpiece 4 is firmly fixed, operations such as assembling, detecting, or repairing the workpiece 4 can be carried out, which can effectively ensure the operation quality.

[0046] After the operations such as assembling, detecting, or repairing the workpiece 4 are completed, the locking component 32 is adjusted to the unlocking state. The locking component 32 drives the positioning component 31 to move from the first end of the substrate 11 towards the second end of the substrate 11. When the positioning component 31 moves to a suitable position, the workpiece 4 can be conveniently taken out.

[0047] In the embodiment of the present invention, the limiting component 2 and the positioning mechanism 3 are diagonally arranged. The locking component 32 is movably arranged on the base 1. The locking component 32 drives the positioning component 31 to move so that the positioning component 31 approaches or moves away from the limiting component 2. Through the movement of the locking component 32 and the switching of the locking component 32 between the unlocking state and the locking state, the limiting component 2 and the positioning component 31 can conveniently clamp and release the workpiece 4, which is beneficial to the convenience of operation.

[0048] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, in an alternative embodiment, the positioning assembly 31 includes a positioning plate 311, a mounting seat 312 and an elastic connecting member 313; the mounting seat 312 is connected to the locking assembly 32, and the mounting seat 312 is provided with a receiving groove; the positioning plate 311 is provided with a positioning groove 3111, the positioning plate 311 is movably disposed on the mounting seat 312, and the groove wall surface of the receiving groove is used to abut against the circumferential surface of the positioning plate 311; one end of the elastic connecting member 313 is connected to the positioning plate 311, and the other end is connected to the mounting seat 312, and at least one of the positioning plate 311 and the mounting seat 312 is detachably connected to the elastic connecting member 313.

[0049] Specifically, the positioning plate 311 is disc-shaped, the positioning groove 3111 is recessed from the circumferential surface of the positioning plate 311 towards the central axis direction of the positioning plate 311, and the positioning groove 3111 penetrates through the top surface and the bottom surface of the positioning plate 311. The positioning plate 311 is movably mounted on the mounting seat 312, and the positioning plate 311 can rotate about its central axis.

[0050] The structure of the mounting seat 312 is not specifically limited. For example, the mounting seat 312 is a rectangular body, and a receiving groove is recessed from one end face of the mounting seat 312 towards the opposite end face. The groove wall surface of the receiving groove is adapted to the circumferential surface of the positioning plate 311, and a part of the circumferential surface of the positioning plate 311 is attached to the groove wall surface of the receiving groove, and there is an appropriate movement gap between the positioning plate 311 and the mounting seat 312.

[0051] The number of the elastic connecting members 313 is two. One elastic connecting member 313 is mounted on the top of the positioning plate 311 and the mounting seat 312, and the other elastic connecting member 313 is mounted on the bottom of the positioning plate 311 and the mounting seat 312. The structures of the two elastic connecting members 313 are the same. The elastic connecting member 313 mounted on the top of the positioning plate 311 and the mounting seat 312 will be described below.

[0052] The elastic connecting member 313 includes two fixing members and an elastic member 3133. The structures of the two fixing members are the same. The two fixing members are defined as the first fixing member 3131 and the second fixing member 3132 respectively. The first fixing member 3131 is vertically arranged on the positioning plate 311, and the second fixing member 3132 is vertically arranged on the mounting seat 312. The end of the first fixing member 3131 away from the positioning plate 311 is provided with a first through hole, and the end of the second fixing member 3132 away from the mounting seat 312 is provided with a second through hole. The elastic member 3133 can be a tension spring. The tension spring includes a tension spring body and hook rings arranged at both ends of the tension spring body. One end of the tension spring is connected to the first through hole through one hook ring, and the other end of the tension spring is connected to the second through hole through the other hook ring. Thus, the movable connection between the positioning plate 311 and the mounting seat 312 is realized through the two fixing members and the elastic member 3133.

[0053] After separating the hook ring at one end of the tension spring from the second through hole of the second fixing member 3132 on the mounting seat 312, rotate the positioning plate 311 around the central axis of the positioning plate 311 to adjust the position of the positioning groove 3111. After adjusting the position of the positioning groove 3111, connect the hook ring at one end of the tension spring to the second through hole. When the shape of the workpiece 4 is irregular, by adjusting the position of the notch of the positioning groove 3111, the contact area between the groove wall surface of the positioning groove 3111 and the circumferential surface of the workpiece 4 is maximized, which is beneficial to improving the clamping stability of the workpiece 4. It can be understood that according to the shape of the workpiece 4, before clamping, the position of the positioning groove 3111 can be roughly adjusted by rotating the positioning plate 311; after the groove wall surface of the positioning groove 3111 abuts against the circumferential surface of the workpiece 4, the position of the positioning groove 3111 can be finely adjusted by rotating the positioning plate 311 to maximize the contact area between the groove wall surface of the positioning groove 3111 and the circumferential surface of the workpiece 4, further ensuring the clamping stability.

[0054] In the embodiment of the present invention, the positioning plate 311 is rotatably installed on the mounting seat 312. The positioning plate 311 and the mounting seat 312 are connected by an elastic connecting member 313. The two fixing members are respectively arranged on the positioning plate 311 and the mounting seat 312. The two ends of the elastic member 3133 are respectively connected to the two fixing members. The elastic member 3133 is beneficial to conveniently realizing the fixation and separation of the positioning plate 311 and the mounting seat 312, so as to adjust the position of the positioning groove 3111 to adapt to the irregular-shaped workpiece 4 and improve the versatility of the fixture; at the same time, by adjusting the position of the positioning groove 3111, the contact area between the groove wall surface of the positioning groove 3111 and the circumferential surface of the workpiece 4 is maximized, which is beneficial to further ensuring the clamping stability of the workpiece 4.

[0055] In an alternative embodiment, a plurality of positioning grooves 3111 are provided on the circumferential surface of the positioning plate 311, and one of the plurality of positioning grooves 3111 is used to abut against the workpiece 4.

[0056] Specifically, a plurality of positioning grooves 3111 are provided along the circumferential direction of the positioning plate 311. The number of the positioning grooves 3111 is set according to actual requirements. The shape of the positioning grooves 3111 can be fan-shaped, L-shaped, V-shaped, U-shaped, or arc-shaped, etc., so as to adapt to workpieces 4 of various irregular shapes.

[0057] When the shape of the workpiece 4 is irregular, rotate the positioning plate 311 to adjust the positions of the plurality of positioning grooves 3111 on the positioning plate 311, so that the positioning groove 3111 with the best matching degree with the workpiece 4 faces the workpiece 4. After the limiting component 2 and the positioning component 31 clamp the workpiece 4, ensure that the contact area between the groove wall surface of the positioning groove 3111 and the circumferential surface of the workpiece 4 is maximized, thereby ensuring the stability of clamping the workpiece 4. A plurality of positioning grooves 3111 are provided on the positioning plate 311, and the plurality of positioning grooves 3111 have different shapes to match workpieces 4 of various irregular shapes, which is beneficial to improving the versatility of the fixture.

[0058] Such as Figure 5 and Figure 6 As shown in the figure, in an alternative embodiment, the mounting seat 312 includes a mounting block 3121 and a limiting plate 3122; two limiting plates 3122 are provided on opposite sides of the mounting block 3121, and the mounting block 3121 is provided with a receiving groove, and the limiting plate 3122 covers the receiving groove; the mounting block 3121 and the two limiting plates 3122 enclose a receiving space, and a part of the positioning plate 311 is embedded in the receiving space.

[0059] Specifically, the mounting seat 312 includes a mounting block 3121 and a limiting plate 3122. The mounting block 3121 can be a square body, and a receiving groove is formed by recessing from one end face of the mounting block 3121 towards the other end face opposite to the mounting block 3121. The two limiting plates 3122 are respectively mounted on the top surface and the bottom surface of the mounting block 3121, and the two limiting plates 3122 respectively cover the upper and lower parts of the receiving groove. It can be understood that the limiting plate 3122 only covers a part of the receiving groove.

[0060] The limiting plate 3122 only covers a part of the receiving groove to avoid the first fixing member 3131 mounted on the positioning plate 311, and at the same time expose an appropriate area of the positioning plate 311, which is convenient for rotating the positioning plate 311 and is beneficial to the convenience of operation.

[0061] The accommodation groove provided on the mounting block 3121 and the two limit plates 3122 enclose a containing space. A part of the positioning plate 311 is embedded in the containing space. The wall surface of the accommodation groove abuts against the circumferential surface of the positioning plate 311. The mounting block 3121 can limit the positioning plate 311 in the horizontal direction, and the two limit plates 3122 limit the positioning plate 311 in the vertical direction. The positioning plate 311 is limited from two mutually perpendicular directions, ensuring the stability of the fixed positioning plate 311 and effectively ensuring the firmness of the clamped workpiece 4.

[0062] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, in an alternative embodiment, the positioning mechanism 3 further includes a moving assembly 33. The moving assembly 33 includes a guide rod 331 and a connecting frame 332. The connecting frame 332 is connected to the locking assembly 32. The connecting frame 332 is provided with a guide hole. The guide rod 331 passes through the guide hole. The mounting seat 312 is connected to the end of the guide rod 331 away from the connecting frame 332; the guide rod 331 can move along the axis direction of the guide hole to drive the positioning assembly 31 to move closer to or away from the limiting assembly 2.

[0063] Specifically, the moving assembly 33 includes a guide rod 331 and a connecting frame 332. The structure of the connecting frame 332 is not specifically limited. For example, the connecting frame 332 is a U-shaped connecting frame. One end of the connecting frame 332 is provided with a guide hole. The axis of the guide hole is perpendicular to and intersects with the central axis of the positioning plate 311. The central plane of the guide rod 331 can coincide with the central plane of the mounting seat 312.

[0064] After the guide rod 331 passes through the guide hole, one end of the guide rod 331 is connected to the mounting block 3121, and a driving member can be provided at the other end of the guide rod 331. The driving member can drive the guide rod 331 to move along the axis direction of the guide hole. After the locking assembly 32 drives the positioning assembly 31 to move close to the workpiece 4, the driving member drives the guide rod 331 to move along the guide hole towards the direction close to the limiting assembly 2. The guide rod 331 drives the positioning assembly 31 to gradually approach the workpiece 4 until the wall surface of the positioning groove 3111 abuts against the workpiece 4; the driving member drives the guide rod 331 to move along the guide hole towards the direction close to the locking assembly 32. The guide rod 331 drives the positioning assembly 31 to gradually move away from the workpiece 4 so that the positioning plate 311 is separated from the workpiece 4.

[0065] Further, the stroke of the locking assembly 32 is set according to actual requirements, and the stroke of the guide rod 331 is set according to actual requirements. By moving the locking assembly 32, the positioning plate 311 approaches or moves away from the workpiece 4 along the first direction; by moving the guide rod 331, the positioning plate 311 approaches or moves away from the workpiece 4 along the second direction to adapt to workpieces 4 of different length dimensions and width dimensions, which is beneficial to further improving the versatility of the fixture.

[0066] As Figure 2 , Figure 3 and Figure 4 shown, in an alternative embodiment, the locking assembly 32 includes a connecting seat 321, a connecting block 322 and a locking member 323; the connecting seat 321 is disposed on one side of the base 1, the connecting block 322 is disposed on the other side of the base 1, the connecting seat 321 includes a first connecting plate 3211 and a second connecting plate 3212 perpendicular to each other, the first connecting plate 3211 is connected to the connecting frame 332, and the second connecting plate 3212 is disposed in contact with the base 1; the base 1 is provided with a chute 111, the locking member 323 passes through the second connecting plate 3212 and the chute 111 and is connected to the connecting block 322, the locking member 323 has an unlocked state and a locked state, in the unlocked state, the locking member 323 can move along the chute 111; in the locked state, the locking member 323 is used to tightly connect the second connecting plate 3212 and the base 1.

[0067] Specifically, the locking assembly 32 includes a connecting seat 321, a connecting block 322 and a locking member 323, the connecting seat 321 is located on the first side of the substrate 11, the connecting block 322 is located on the second side of the substrate 11, and the connecting seat 321 and the connecting block 322 can be connected by a connecting column.
