[0004] To solve the above technical problems, the present invention provides a novel workpiece stroke detection fixture, comprising a support, a counterweight structure, a fixed base for mounting the workpiece, and a length measuring tool. The upper part of the support is provided with a mounting groove, in which a linear bearing is installed. The guide rod at the lower end of the counterweight structure is inserted into the linear bearing and can move along the linear bearing.

[0005] The upper end of the bracket is also provided with a mounting plate, and the length measuring tool is mounted on the mounting plate with the lower detection end abutting against the upper surface of the detection plate of the counterweight structure;

[0006] The lower part of the bracket is provided with a U-shaped sliding groove, and the fixed seat can move along the sliding groove.

[0007] Furthermore, the counterweight structure includes a counterweight block, the guide rod, screws, and the detection plate. The detection plate is located directly below the counterweight block. The upper end of the guide rod passes through the detection plate and is inserted into the interior of the counterweight block. The counterweight block and the guide rod are detachably connected by screws.

[0008] Furthermore, the root of the detection plate is annular and located precisely within the mounting groove.

[0009] Furthermore, the opening of the groove is a flared, trumpet-shaped opening.

[0010] Furthermore, the fixing seat is annular, and the root of the groove is an arc shape that matches the fixing seat.

[0011] Furthermore, the inner ring of the fixing base is provided with three spiral notches, which match the protrusions of the workpiece's outer shell, and the rubber ring of the workpiece can be screwed into the notches.

[0012] Furthermore, the length measuring tool is a dial indicator or a micrometer.

[0013] The beneficial effects of this utility model are:

[0014] This utility model includes a bracket, a counterweight structure, a fixed base for mounting the workpiece, and a length measuring tool. The workpiece (such as a motor assembly) is mounted on the fixed base, and then the fixed base is slid into the slide groove. When it is almost at the bottom of the slide groove, the counterweight structure is lifted slightly so that the part on the workpiece is directly below the guide rod. Then, the motor of the motor assembly rotates to drive the zero-stage upward movement, which will raise the guide rod and the entire counterweight mechanism. Finally, the movement stroke of the part can be detected by measuring the upward stroke of the detection plate. This fixture is easy to use, has high measurement accuracy, and simulates the movement stroke of the part under load, which is closer to the actual working situation and the measurement results are more accurate.

[0024] The following specific embodiments illustrate the detailed implementation of this utility model. Those skilled in the art can easily understand the advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented in other different ways, that is, different modifications and changes can be made without departing from the scope disclosed in this utility model.

[0025] The descriptions of positions such as up, down, left, and right in this embodiment are based on the orientation in the accompanying drawings, have no special meaning, and are not intended to limit the scope of protection of this utility model.

[0026] Example: A novel workpiece stroke detection fixture, such as Figures 1 to 5 As shown, in this embodiment, the workpiece 10 is a motor assembly, and the end of the motor assembly has a part 101. The outer shell of the motor assembly has a protrusion 102. The tooling includes a bracket 1, a counterweight structure 2, a fixing seat 3 for mounting the workpiece 10, and a length measuring tool (not shown in the figure). The upper part of the bracket is provided with a mounting groove 11, and a linear bearing 12 is installed in the mounting groove. The guide rod 21 at the lower end of the counterweight structure is inserted into the linear bearing and can move along the linear bearing.

[0027] The upper end of the bracket is also provided with a mounting plate 13, and the length measuring tool is mounted on the mounting plate (in this embodiment, the mounting plate has a mounting hole 131) and the lower detection end abuts against the upper surface of the detection plate 22 of the counterweight structure;

[0028] The lower part of the bracket is provided with a U-shaped sliding groove 14, and the fixed seat can move along the sliding groove.

[0029] In this embodiment, the counterweight structure 2 includes a counterweight block 23, a guide rod 21, screws (not shown in the figure), and a detection plate 22. The detection plate is located directly below the counterweight block. The upper end of the guide rod passes through the detection plate and inserts into the interior of the counterweight block. The counterweight block and the guide rod are detachably connected by screws. The counterweight block, guide rod, and detection plate are detachably connected, allowing for easy replacement of counterweight blocks of different weights. The replacement process is simple, quick, and convenient.

[0030] In this embodiment, the root of the detection plate is annular and located precisely within the mounting groove. The movement distance of the part at the end of the workpiece is converted into the movement distance of the detection plate; therefore, measuring the movement distance of the detection plate allows for the detection of the movement distance of the part at the end of the workpiece.

[0031] In this embodiment, the length measuring tool is a dial indicator or a micrometer indicator. It is used to measure the vertical movement of the detection plate.

[0032] In this embodiment, the opening of the slide groove is a flared, trumpet-shaped opening. This serves as a guide, facilitating the smooth sliding of the fixing seat into the slide groove.

[0033] In this embodiment, the fixing seat is annular, and the root of the sliding groove is an arc shape that matches the fixing seat.

[0034] In this embodiment, the inner ring of the fixing base has three spiral notches 31, which match the protrusions 102 on the outer shell of the workpiece, and the rubber ring (not shown in the figure) attached to the workpiece can be screwed into the notches. This structural design is based on the shape of the workpiece, and it is sufficient to fix the workpiece. Different fixing bases with different structures can be set according to different workpieces, and even other fasteners can be used to fix the workpiece to the fixing base.

[0035] In this embodiment, the bracket is made of aluminum alloy, which reduces the weight of the entire tooling.

[0036] The working principle and process of this utility model:

[0037] Install the motor assembly onto the fixed base, then slide the fixed base into the slide groove. When it is almost at the bottom of the slide groove, lift the counterweight structure slightly so that part 101 on the workpiece is directly below the guide rod. Then, the motor of the motor assembly rotates to drive the zero-stage upward movement, which will cause the guide rod and the entire counterweight mechanism to rise. Finally, the movement stroke of the part can be detected by measuring the upward stroke of the detection plate. This method is convenient, has high measurement accuracy, and simulates the movement stroke of the part under load, which is closer to the actual working conditions and the measurement results are more accurate.

[0038] The above description is merely an embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
