DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1

[0021] See also Figure 1-3 The utility model provides the following technical solutions: a positioning fixture for a movable joint, including a base 4, a fixing component 6 is provided on the surface of the base 4, a fixing frame 2 is connected to the top of the fixing component 6, a lifting groove 3 is provided inside the fixing frame 2, a lifting mechanism 1 is embedded inside the lifting groove 3, a directional component 5 is connected to the side of the lifting mechanism 1 on one side, and a clamping block 7 is embedded inside the directional component 5.

[0022] Specifically, the fixing assembly 6 includes a screw 61, a transmission block 62 and a through slot 63. The surface of the base 4 is provided with a through slot 63, and the screw 61 is embedded inside the through slot 63. The bottom of the fixing frame 2 is connected to the transmission block 62. The surface of the transmission block 62 is tightly fitted with the inner wall of the through slot 63, and the thread directions of the surfaces at both ends of the screw 61 are opposite.

[0023] By adopting the above technical solution, when the screw rod 61 is rotated and meshed with the transmission block 62, the through groove 63 limits the transmission block 62. Since the threads on the two end surfaces of the screw rod 61 are in opposite directions, the two transmission blocks 62 can respectively drive the fixing frame 2 to move toward each other. When the two clamping blocks 7 are brought close to each other, the movable joint can be clamped and fixed. This positioning fixture makes the installation operation of the movable joint easier and has a better use effect.

[0024] Specifically, an L-shaped handle 65 is connected to the side end of the screw rod 61 , a positioning sleeve 66 is provided on the side of the base 4 , and a circular positioning block 64 is sleeved on the surface of the screw rod 61 inside the positioning sleeve 66 .

[0025] By adopting the above technical solution, the positioning sleeve 66 limits the positioning block 64, and the rotating handle 65 can drive the screw rod 61 to limit the rotation. The L-shaped handle 65 can make the movement and adjustment operation of the clamping block 7 more labor-saving.

[0026] When this embodiment is used, the movable joint is placed between the two clamping blocks 7 above the base 4, and the positioning sleeve 66 limits the positioning block 64. The rotating handle 65 can drive the screw 61 to limit rotation, and under the meshing connection between the screw 61 and the transmission block 62, the through groove 63 limits the transmission block 62. Since the threads on the two end surfaces of the screw 61 are in opposite directions, the two transmission blocks 62 can respectively drive the fixing frame 2 to move toward each other. The two clamping blocks 7 are close to each other to complete the clamping and fixing of the movable joint. This positioning fixture makes the installation operation of the movable joint easier and the use effect is better. The lifting mechanism 1 can control the lifting block to slide in the lifting slot 3 to adjust the installation and fixing height of the movable joint.

[0027] Example 2

[0028] The present embodiment is different from the embodiment 1 in that the orientation assembly 5 comprises a side block 51, a connecting seat 53, a clamping block 54, a spring 55 and a gear 57; the side of the lifting mechanism 1 on one side is connected to the side block 51; the bottom of the side block 51 is connected to the connecting seat 53; the inside of the connecting seat 53 is embedded with the clamping block 54; the bottom of the clamping block 54 is provided with a spring 55; and the surface of the clamping block 7 is covered with a gear 57.

[0029] Specifically, the top of the clamping block 54 is in a toothed structure, and the clamping block 54 is tightly meshed with the side of the gear 57 .

[0030] By adopting the above technical solution, under the elastic force of the spring 55, the block 54 can be meshed with the gear 57 to complete the angle positioning of the movable joint at the side end of the clamping block 7, which can achieve a better installation and positioning effect of the movable joint. The angle of the movable joint can be rotated to adjust the angle of the movable joint by separating the block 54 from the gear 57.

[0031] Specifically, the side end of the clamping block 7 inside the side block 51 is connected to a disc-shaped limiting block 52 , and the side of the clamping block 54 is connected to a control block 56 .

[0032] By adopting the above technical solution, the limit block 52 and the side block 51 can be rotated to limit the clamp block 7 to adjust the angle of the movable joint, so that the clamp block 54 and the gear 57 can be firmly engaged to better adjust and position the clamp block 7.

[0033] When this embodiment is in use, under the elastic force of the spring 55, the clamping block 54 can be meshed with the gear 57 to complete the angular positioning of the movable joint at the side end of the clamping block 7, which can achieve a better installation and positioning effect of the movable joint. The moving control block 56 drives the clamping block 54 to retract into the connecting seat 53 and separate from the gear 57. The limit block 52 and the side block 51 are rotated to limit the position, so that the clamping block 7 can be rotated to adjust the angle of the movable joint.

[0034] The structure and use principle of the lifting mechanism 1, fixed frame 2, lifting slot 3, base 4 and clamping block 7 in the utility model have been disclosed in Chinese patent application No. 202020640951.6, which discloses a clamp for grinding a movable nut. Its working principle is to control the two clamping blocks 7 to move toward each other to complete the clamping and fixing of the movable joint. The lifting mechanism 1 can control the lifting block to slide in the lifting slot 3, thereby adjusting the fixing height of the movable joint.

[0035] Working principle and use process of the utility model: When the utility model is used, the movable joint is placed between the two clamping blocks 7 above the base 4, and the positioning sleeve 66 limits the positioning block 64. The rotating handle 65 can drive the screw rod 61 to limit the rotation, and under the meshing connection between the screw rod 61 and the transmission block 62, the through groove 63 limits the transmission block 62. Because the thread directions of the surfaces at both ends of the screw rod 61 are opposite, the two transmission blocks 62 can respectively drive the fixed frame 2 to move toward each other, and the two clamping blocks 7 can be close to each other to complete the clamping and fixing of the movable joint. The positioning clamp makes the installation operation of the movable joint easier and has a better use effect. The lifting mechanism 1 can control the lifting block to slide in the lifting slot 3 to adjust the installation and fixing height of the movable joint. Under the elastic force of the spring 55, the clamping block 54 can be engaged with the gear 57 to complete the angular positioning of the movable joint at the side end of the clamping block 7, which can achieve a better installation and positioning effect of the movable joint. The moving control block 56 drives the clamping block 54 to retract into the connecting seat 53 and separate from the gear 57. The limit block 52 and the side block 51 are rotated to limit the rotation of the clamping block 7 to adjust the angle of the movable joint.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
