The technical scheme is as follows:
the special-shaped pointer clamping device for angle measurement comprises a support, a support plate and a pointer, wherein the support plate comprises a first support plate and a second support plate, the first support plate and the second support plate are integrally formed into an L-shaped structure, the first support plate is fixedly connected with the support, so that a half-square-shaped fixed space is formed between the support plate and the support, a pointer fixing hole is formed in the second support plate, and the pointer is installed in the pointer fixing hole.
Furthermore, the surface of the support is provided with a sunken sliding groove, and an opening structure communicated with the outside is formed on the side, far away from the support, where the support is connected with the support plate.
Furthermore, a plurality of first screws are arranged on the second support plate, and the first screws penetrate through the second support plate and are in threaded connection with the second support plate.
Furthermore, a plurality of second screws are installed on the support, the second screws penetrate through the support and enter the sliding groove, and the second screws are in threaded connection with the support.
Furthermore, the pointer fixing device further comprises a third screw, wherein the third screw is installed on the second support plate in a threaded mode, and the tail end of the third screw can enter the pointer fixing hole and fix the pointer.
Further, the indication direction of the pointer is parallel to the opening direction of the sliding chute.
Further, the first support plate and the support are fixedly connected through a fourth screw.
Compared with the prior art, the utility model have following advantage:
the utility model discloses a mechanical structure is simple, through the combination of support and L type extension board, fixes the pointer with the screw, and the device is arranged in finished piece detection rotation angle in-process, measures heterotypic pointer clamping on the contact arm of finished piece, plays assistance-localization real-time's effect, makes operating personnel accomplish accurate swift detection to the finished piece.

Detailed Description
The following description sufficiently illustrates specific embodiments of the invention to enable those skilled in the art to practice and reproduce it.
As shown in fig. 1, 2 and 3, the present embodiment provides a special-shaped pointer clamping device for angle measurement, including a support 1, a support plate 2 and a pointer 3, where the support plate 2 includes a first support plate 201 and a second support plate 202, the first support plate 201 and the second support plate 202 are integrally formed into an L-shaped structure, the first support plate 201 and the support are fixedly connected by a fourth screw 11, in the present embodiment, the first support plate 201 is disposed perpendicular to the support, so that a half-square-shaped fixing space 4 is formed between the support plate and the support, a pointer fixing hole 22 is disposed on the second support plate 202, and the pointer 3 is mounted in the pointer fixing hole 22.
As shown in fig. 2, a concave sliding groove 13 is arranged on the surface of the support, and an opening structure communicated with the outside is formed on the side, away from the support 1, of the sliding groove 13, which is connected with the support plate 2; a plurality of first screws 23 are arranged on the second support plate 202, and the first screws 23 penetrate through the second support plate 202 and are in threaded connection with the second support plate 202; a plurality of second screws 12 are arranged on the support, the second screws 12 penetrate through the support and enter the sliding groove 13, and the second screws 12 are in threaded connection with the support.
Furthermore, it is also possible to envisage including a third screw 21, which is screwed onto the second plate and the end of which can enter the needle-fixing hole 22 and fix the needle 3, so that the length of the needle extension can be adjusted by adjusting the third screw 21.
It should be noted that the indication direction of the pointer is parallel to the opening direction of the sliding slot 13, so that when the contact arm of the workpiece is fixed in the fixing space 4, the contact arm enters from the opening of the sliding slot, the contact arm is limited and fixed in the sliding slot and the fixing space by adjusting the second screw 12 and the first screw 23, and the contact side of the contact arm and the switch pressing plate is flush with the pointer, thereby measuring the rotation angle of the contact arm.
The terminology used herein is for the purpose of description and illustration, rather than of limitation. As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
