Description

Technical Field

[0001] This utility model relates to the field of bushing measurement technology, and in particular to a bushing measuring instrument. Background Technology

[0002] The bushing structure is used to fit onto the transmission shaft structure. It is mostly a ring-shaped structure. After the bushing is manufactured, the dimensions of the bushing assembly are inspected. This measuring instrument is used to inspect the dimensions of the bushing assembly.

[0003] When measuring the dimensions of a bushing, the thickness and diameter of the bushing's ring wall are inspected. However, during inspection, ordinary measuring tools have a simple structure and require manual control of the dimensions. The dimensional parameters are repeatedly measured against the ring wall and outer wall of the bushing. During inspection, the manual holding and handling of the bushing and measuring tool can easily lead to instability and shaking, affecting the accuracy of parameter reading and resulting in poor measurement results. Utility Model Content

[0004] The purpose of this invention is to provide a bushing measuring instrument.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bushing measuring instrument includes a support plate, the top of which is rectangular and the bottom is concave. A fixed post is fixedly connected to the center end wall on both sides of the top of the support plate. A rectangular groove is formed inside the support plate near the end wall of the fixed post. A spring post is horizontally placed and fixedly connected within the groove. A block is movably connected to the end of the spring post and is movably connected to the groove. Slides are formed on both sides of the upper end wall of the support plate for slidingly connecting the block and communicating with the groove. A counterpost is fixed to the top wall of the block, opposite to the fixed post and cooperating to clamp the bushing ring wall. A scale mark for reading the bushing size is formed on the upper end wall of the support plate near the slide.

[0007] Preferably, the bottom of both the fixed column and the opposing column are cylindrical structures, and the top end walls of both the fixed column and the opposing column are inclined, so that when the fixed column and the opposing column are in close contact, they form an opening for inserting into the bushing ring wall.

[0008] Preferably, the inner block forms an elastic structure with the support plate via a spring column, allowing the inner block to move toward the side of the inner groove closer to the support plate.

[0009] Preferably, a rectangular measuring groove is provided on the lower end wall of the support plate near the slide rail, opposite to the inner groove, and a rectangular measuring block is movably connected in the measuring groove.

[0010] Preferably, there are two gauge blocks and two gauge grooves, with the gauge grooves connected to the slide rails, and the length of the gauge grooves being greater than the length of the inner grooves.

[0011] Preferably, a measuring column is fixedly connected to the top wall of the gauge block, and a pair of pointers for indicating scale markings are fixedly connected to the front and rear side walls of the measuring column near the gauge block and to the front and rear end walls of the measuring column near the inner block.

[0012] This utility model has at least the following beneficial effects:

[0013] The upper wall of the support plate is used to place the shaft assembly, which facilitates measurement after the shaft assembly is supported, making the measurement more stable. At the same time, during measurement, the ring wall of the shaft assembly is pressed down along the space between the fixed column and the counter column, and inserted through the joint formed between the top of the fixed column and the counter column. The counter column is squeezed, so that the elastic and movable counter column moves away from the fixed column and moves laterally. At this time, the counter column and the fixed column hold the ring wall of the shaft sleeve, and the end wall of the shaft assembly is simply positioned. At the same time, as the counter column moves, the pointer on the end wall of the counter column moves accordingly. At this time, the scale mark is read to obtain the thickness of the ring wall of the shaft sleeve, achieving the purpose of quickly and simply measuring the size of the shaft sleeve.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Please see Figure 1-4This utility model provides a technical solution for a bushing measuring instrument:

[0022] like Figure 1-4 As shown, a bushing measuring instrument includes a support plate 1. The top of the support plate 1 is rectangular and the bottom is concave. A fixed column 2 is fixedly connected to the center end wall on both sides of the top of the support plate 1. A rectangular inner groove 3 is opened in the support plate 1 near the end wall of the fixed column 2. A spring column 4 is horizontally placed and fixedly connected in the inner groove 3. An inner block 5 is movably connected to the end of the spring column 4 and is movably connected to the inner groove 3. A slide 6 is opened on both sides of the upper end wall of the support plate 1 to slide the inner block 5 and communicate with the inner groove 3. A counter column 7 is fixedly connected to the top wall of the inner block 5 to be opposite to the fixed column 2 and to cooperate in clamping the bushing ring wall. A scale mark 8 for reading the bushing size is opened on the upper end wall of the support plate 1 near the slide 6.

[0023] The bottom of both the fixed column 2 and the counter column 7 are cylindrical structures, and the top of both the fixed column 2 and the counter column 7 are inclined. When the fixed column 2 and the counter column 7 are in close contact, they form a joint that can be inserted into the sleeve ring wall. The inner block 5 forms an elastic structure with the support plate 1 through the spring column 4, so that the inner block 5 moves toward the inner groove 3 near the support plate 1.

[0024] A rectangular measuring groove 12 is provided on the lower wall of the support plate 1 near the slide rail 6, opposite to the inner groove 3. A rectangular measuring block 9 is movably connected in the measuring groove 12. There are two measuring blocks 9 and two measuring grooves 12. The measuring groove 12 is connected to the slide rail 6. The length of the measuring groove 12 is greater than the length of the inner groove 3. A measuring column 10 is fixed to the top wall of the measuring block 9. A pair of pointers 11 for indicating the scale mark 8 are fixed to the front and rear side walls of the measuring column 10 near the measuring block 9 and the front and rear end walls of the measuring column 7 near the inner block 5.

[0025] Working principle:

[0026] The upper wall of the support plate 1 is used to place the shaft assembly, which facilitates measurement after the shaft assembly is supported and makes the measurement more stable. At the same time, during measurement, the ring wall of the shaft assembly is pressed down along the space between the fixed column 2 and the counter column 7, and inserted through the joint formed between the top of the fixed column 2 and the counter column 7. The counter column 7 is squeezed, so that the elastic and movable counter column 7 moves away from the fixed column 2 and moves to the side. At this time, the counter column 7 and the fixed column 2 hold the ring wall of the shaft sleeve, and the end wall of the shaft assembly is simply positioned. At the same time, when the counter column 7 moves, the pointer 11 at the end wall of the counter column 7 moves accordingly. At this time, the scale mark 8 is read to obtain the thickness of the ring wall of the shaft sleeve, so as to achieve the purpose of quickly and simply measuring the size of the shaft sleeve.

[0027] Then, the bushing is positioned on the support plate 1 in a relatively stable state, so as to make stable measurement of the bushing's dimensional parameters. At this time, the measuring column 10 is moved to the side, and the measuring block 9 slides and moves to the side in the measuring groove 12, making the movement of the measuring column 10 more stable. After the measuring column 10 is in contact with the end wall of the bushing, the pointer 11 at the measuring column 10 is used to read the scale mark 8 and obtain the diameter of the bushing. The measurement efficiency is high.

[0028] When the column 7 moves laterally, the inner block 5 fixed at the bottom of the column 7 moves laterally within the inner groove 3 to facilitate the stable movement of the inner block 5. At the same time, the spring column 4 applies a force to the inner block 5 in the direction of the axis of the fixed column 2, so that the fixed column 2 and the column 7 form a clamp and automatically clamp the bushing ring wall.

[0029] Slide 6 is used to connect the inner block 5 and the measuring block 9 to the column 7 and measuring column 10 respectively.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
