[0035] Hereinafter, the embodiments will be described with reference to the drawings. In addition, the embodiments shown below do not limit the content of the utility model described in the claims in any way. In addition, all the contents of the configurations shown in the following embodiments are not limited to those necessary for the solution of the utility model described in the claims. It should be noted that, for the sake of convenience of description, only the parts related to the utility model are shown in the drawings. Without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.

[0036] The embodiment of the present utility model discloses a contour gauge dimension measuring tooling, so that the connecting rod component can be clamped to an accurate position at one time, avoiding the problem in the prior art that when using a V-shaped iron block, multiple adjustments are required and it is impossible to locate to an accurate position at one time.

[0037] As Figure 1 shown, the contour gauge dimension measuring tooling disclosed in the embodiment of the present utility model includes a positioning base plate 100, a clamping seat 300 and a clamping pressure plate 400. Among them, a positioning portion 101 is provided at the bottom of the positioning base plate 100, and the positioning portion 101 is used to cooperate with the positioning groove of the contour gauge workbench. The structural form of the positioning portion 101 should be designed according to the structure of the positioning groove on the contour gauge workbench so that it can be embedded in the positioning groove of the contour gauge workbench, enabling the contour gauge dimension measuring tooling to complete rapid positioning with the contour gauge workbench.

[0038] The clamping seat 300 can be arranged on the positioning base plate 100 directly or indirectly, and the clamping seat 300 has a clamping groove 304 for supporting the connecting rod of the connecting rod component, and the connecting rod of the connecting rod component is supported in the clamping groove 304. The clamping groove 304 can be arranged at the top of the clamping seat 300, and the opening side of the clamping groove 304 is located at the top, so that the connecting rod can be placed into the clamping groove 304 through the top opening.

[0039] In this embodiment, the extending direction of the positioning portion 101 is parallel to the extending direction of the clamping groove 304. It should be noted that the extending direction of the positioning portion 101 is also the axial direction of the connecting handle after the connecting handle is inserted into the clamping groove 304. By designing the extending direction of the positioning portion 101 to be parallel to the extending direction of the clamping groove 304, the present utility model can ensure that after the connecting handle is clamped into the clamping groove 304, the axis of the connecting handle is parallel to the positioning groove on the contour measuring instrument workbench. And the contour measuring instrument probe is also positioned in the positioning groove of the contour measuring instrument workbench. Therefore, the moving direction of the contour measuring instrument probe is parallel to the positioning groove of the contour measuring instrument workbench, that is, parallel to the axial direction of the connecting handle.

[0040] The clamping pressing plate 400 is detachably fixed on the clamping seat 300 and is used to close the opening side of the clamping groove 304 to clamp the connecting handle in the clamping groove 304. In this embodiment, by adding the clamping pressing plate 400, the connecting handle supported in the clamping groove 304 can be pressed tightly to prevent the connecting handle from sliding in the clamping groove 304 and causing scratches on the connecting handle component.

[0041] For the contour measuring instrument dimension measuring tooling provided by the present utility model, a positioning portion 101 is provided at the bottom of its positioning base plate 100. Through the positioning portion 101, it can be positioned on the contour measuring instrument workbench together with the contour measuring instrument probe, so as to ensure the positional relationship between the contour measuring instrument dimension measuring tooling and the contour measuring instrument probe. Since the extending direction of the positioning portion 101 is parallel to the extending direction of the clamping groove 304 of the clamping seat 300, it can be ensured that the clamping groove 304 is parallel to the moving direction of the contour measuring instrument probe, that is, it is ensured that the axis of the connecting handle component is parallel to the moving direction of the contour measuring instrument probe after each clamping. By providing the positioning portion 101, the present utility model can ensure that after the positioning portion 101 is positioned in the positioning groove of the contour measuring instrument workbench, the clamping groove 304 is parallel to the moving direction of the contour measuring instrument probe, without adjustment, and the connecting handle component can be clamped to the accurate measuring position at one time, improving the measurement accuracy.

[0042] In a specific embodiment of the present utility model, the positioning portion 101 may include at least two positioning pins, and the arrangement direction of each positioning pin is parallel to the extending direction of the clamping groove 304. That is, each positioning pin is arranged in a straight line, and this straight line is parallel to the extending direction of the clamping groove 304. At least two positioning pins can ensure that after each positioning pin slides into the positioning groove of the contour measuring instrument workbench, the contour measuring instrument dimension measuring tooling can be prevented from deflecting.

[0043] An external thread portion may be provided at the end of the positioning pin, and a corresponding internal thread portion is provided at the bottom of the positioning base plate 100. The positioning pin is installed on the positioning base plate 100 through the cooperation of the external thread portion and the internal thread portion. The positioning pin can also be fixed on the positioning base plate 100 by other means, such as welding, clamping, riveting, etc.

[0044] It should be noted that the positioning portion 101 can also adopt other solutions, such as a track structure, a slider structure, etc., and is not limited to the implementation manner of the positioning pin. As long as it can be embedded in the positioning groove of the profilometer workbench.

[0045] Furthermore, the alignment straight line of each positioning pin is coplanar with the symmetry plane of the clamping groove 304. The symmetry plane of the clamping groove 304 is a symmetry plane parallel to the extending direction of the clamping groove 304. The clamping seat 300 is usually arranged in a vertical state, and the symmetry plane of the clamping groove 304 is a vertical plane. The alignment straight line of the positioning pin and the extending direction of the clamping groove 304 are arranged in the same vertical plane, so that after the connecting handle is inserted into the clamping groove 304, the axis direction of the connecting handle and the alignment direction of the positioning pin are in the same vertical plane, and this vertical plane passes through the positioning groove of the profilometer workbench into which the positioning pin is inserted.

[0046] In this embodiment, by designing the alignment straight line of each positioning pin to be coplanar with the symmetry plane of the clamping groove 304, the position of the axis direction of the connecting handle can be judged through the positioning groove of the profilometer workbench into which the positioning pin is inserted.

[0047] As Figure 2 and Figure 3 shown, in a specific embodiment of the present utility model, the clamping pressing plate 400 includes a pressing plate main body portion and pressing plate assembly portions located at both ends of the pressing plate main body portion. The pressing plate assembly portions can be fixed on the clamping seat 300 through pressing plate fasteners 401. Correspondingly, the top of the clamping seat 300 also has a clamping seat upper assembly portion 303 corresponding to the pressing plate assembly portions, and the clamping seat upper assembly portion 303 is arranged on both sides of the clamping groove 304.

[0048] Threaded clamping seat holes for cooperating with the pressing plate fasteners 401 need to be opened on the clamping seat upper assembly portion 303, and pressing plate fastening holes corresponding to the threaded clamping seat holes are opened on the pressing plate assembly portions. After the pressing plate fasteners 401 pass through the pressing plate fastening holes, they are threadedly engaged in the threaded clamping seat holes. By tightening the pressing plate fasteners 401, the pressing plate assembly portions can be pressed by the nuts of the pressing plate fasteners 401, so that the clamping pressing plate 400 is pressed against the connecting handle.

[0049] The pressing plate main body portion is arranged opposite to the clamping groove 304 and extends away from the clamping groove 304 to form an outwardly expanding groove communicating with the clamping groove 304. The connecting handle is clamped in the clamping groove 304 and the outwardly expanding groove. Since the connecting handle is of a cylindrical structure, after the connecting handle is placed in the clamping groove 304, the connecting handle will protrude from the opening side of the clamping groove 304. Therefore, an outwardly expanding groove is provided on the clamping pressing plate 400, so that the connecting handle can be pressed, otherwise the depth of the clamping groove 304 needs to be increased. If the outwardly expanding groove is not provided on the clamping pressing plate 400, the depth of the clamping groove 304 can be increased so that the upper surface of the connecting handle is flush with the opening side of the clamping groove 304, and then the clamping pressing plate 400 is installed to achieve pressing.

[0050] In this embodiment, the opening side of the outward expansion groove faces the clamping groove 304, and the width of the outward expansion groove gradually decreases in the direction from the opening side to the bottom side of the groove. Correspondingly, the opening side of the clamping groove 304 is located at the top of the clamping seat 300, and the width of the clamping groove 304 gradually decreases in the direction from the opening side to the bottom side of the groove.

[0051] Figure 2 In the shown solution, the clamping groove 304 is a V-shaped groove with the opening facing upward, and the outward expansion groove is a trapezoidal groove with the opening facing downward. It should be noted that the width of the clamping groove 304 is not limited in this embodiment. Designing the clamping groove 304 as a V-shaped groove enables the two side walls of the clamping groove 304 to clamp the outer peripheral surface of the connecting handle after the connecting handle is placed into the clamping groove 304, and the position of the connecting handle in the clamping groove 304 is at the position where the width of the clamping groove 304 is equal to the diameter of the connecting handle.

[0052] It should be noted that clamping pressure plates 400 with outward expansion grooves of different depths can be selected, so as to adapt to connecting handles of different diameters. Similarly, the clamping seat 300 with clamping grooves 304 of different sizes can also be selected.

[0053] As Figure 3 shown, the clamping pressure plates 400 are multiple and arranged at intervals along the extension direction of the clamping groove 304. Figure 3 In the shown solution, there are two clamping pressure plates 400, and along the extension direction of the clamping groove 304, the two clamping pressure plates 400 are respectively arranged at both ends of the top of the clamping groove 304. It should be noted that only one clamping pressure plate 400 can also be provided and arranged in the middle of the top of the clamping groove 304.

[0054] In a specific implementation of the present utility model, the clamping seat 300 is arranged on the positioning base plate 100 through the displacement platform 200, and the displacement platform 200 is used to adjust the position of the clamping seat 300 relative to the positioning base plate 100. The displacement platform 200 can adopt a displacement platform with a micrometer screw gauge structure to ensure that the connecting handle component can be moved to the accurate position after being clamped.

[0055] Specifically, the displacement adjustment directions of the displacement platform 200 include a first adjustment direction and a second adjustment direction in the horizontal plane. The first adjustment direction and the second adjustment direction are perpendicular to each other, and at least one of the first adjustment direction and the second adjustment direction is the extension direction of the clamping groove 304.

[0056] In this embodiment, the displacement platform 200 can be adjusted in two adjustment directions, namely the first adjustment direction and the second adjustment direction in the horizontal plane. Thus, the clamping seat 300 provided on the displacement platform 200 and the connecting rod member clamped on the clamping seat 300 can be adjusted to any position within the adjustable range in the horizontal plane. Therefore, the connecting rod member can be adjusted to a suitable position by using the displacement platform 200 according to requirements.

[0057] In a specific embodiment of the present utility model, the clamping seat 300 is fixed to the displacement platform 200 through a clamping seat fastener 302. A lower clamping seat assembly portion 301 may be provided at the bottom of the clamping seat 300, a threaded hole is provided on the displacement platform 200, and a fastening hole is provided on the lower clamping seat assembly portion 301. The clamping seat fastener 302 passes through the fastening hole on the lower clamping seat assembly portion 301 and is screwed into the threaded hole.

[0058] The displacement platform 200 can be fixed to the positioning base plate 100 through a platform fastener 201. Threaded holes may be opened at the bottom of the displacement platform 200, fastening holes are provided on the positioning base plate 100, and the platform fastener 201 passes through the fastening holes on the positioning base plate 100 and is screwed into the threaded holes at the bottom of the displacement platform 200. It should be noted that the displacement platform 200 and the positioning base plate 100 may also be designed as an integral structure.
