Description

Technical Field

[0001] This utility model relates to the field of precision measurement technology, and more specifically, to a parallelism measurement fixture. Background Technology

[0002] Parallelism refers to the degree of parallelism between two surfaces or two axes. It is an important geometric parameter of a material or workpiece. In industrial manufacturing, accurate measurement of parallelism is crucial to ensuring product quality and performance.

[0003] Authorization announcement number "CN218329728U" discloses a parallelism detection device for guide rails, used to measure the parallelism between a first guide rail and a second guide rail. The device is characterized by comprising a balancing fixture mounted on a moving pair of the first guide rail, a magnetic base magnetically attached to the balancing fixture near the second guide rail, a dial indicator whose measuring end is in close contact with the surface of the second guide rail, and a connecting assembly for connecting the dial indicator to the magnetic base in a universal adjustment manner. This device solves the problem of parallelism detection of dual guide rails under large span conditions at a lower cost, reducing errors.

[0004] Currently, when measuring the parallelism of workpieces, tooling fixtures are required. These fixtures are typically slider guide modules. By mounting the measuring device on the slider guide module and allowing it to slide, the measuring device can measure the parallelism of each segment of the workpiece. However, existing tooling fixtures lack damping locking functionality. When moving the measuring device to measure the workpiece's parallelism, the measuring device cannot remain stable in the measuring position, resulting in poor positioning and making it inconvenient for operators to confirm the measurement results. This is especially true in vertical working conditions, and the device is prone to slipping, which can damage it. Utility Model Content

[0019] 3. Beneficial effects

[0020] Compared with existing technologies, the advantages of this utility model are:

[0021] (1) In this scheme, the measuring device is installed on the connecting plate. It can move smoothly through the sliding connection between the slider and the connecting plate to realize the measurement of the parallelism of the workpiece. The connecting plate is equipped with a clamping component, which can lock on the guide rail, so that the measuring device is stable and suspended at the measuring position, which has a positioning effect. It is convenient for the staff to determine the measurement results at any position on the workpiece. After the clamping component locks the guide rail, it can prevent the measuring device from sliding down and causing damage in vertical working conditions.

[0022] (2) In this scheme, the handle is installed on the clamping assembly on one side of the connecting plate. This not only facilitates the locking control of the clamping assembly, but also allows the slider to slide on the guide rail from the bottom by using the handle on one side in conjunction with the clamping assembly. The thrust is applied to the bottom of the slider, avoiding direct pressure on the guide rail and causing deformation, thus ensuring measurement accuracy.

[0023] (3) In this scheme, the two rubber blocks have a certain elasticity, which can improve the locking effect of the clamping assembly on the guide rail, and reduce the wear generated when the clamping assembly and the guide rail are locked, thus extending the service life of the tooling fixture. Multiple positioning pins are arranged in a straight line on the mounting plate, which can position the installation of the guide rail from one side, keep the guide rail straight and fixed, thereby ensuring the measurement accuracy of the workpiece when the measuring device moves.

[0024] (4) In this scheme, a set of two limit blocks are located on both sides of the guide rail, which can effectively prevent the slider from falling off due to exceeding the stroke, thereby damaging the measuring device. The telescopic dust cover is fixed between the top of the slider and a limit block on the upper side. After unfolding, it can protect the guide rail and prevent the guide rail from accumulating dust, getting contaminated with debris, being bumped, etc., which would affect the measurement accuracy.

[0025] (5) In this solution, the reinforcing rib is fixed between the mounting plate and the fixing plate, which can improve the strength and rigidity of the tooling fixture structure. The magnetic seat is fixedly connected to the bottom of the fixing plate, which can realize the assembly and disassembly of the tooling fixture in the measurement area. Compared with the traditional screw fixing, the magnetic seat makes the assembly and disassembly of the tooling fixture faster and can maintain good installation accuracy even when frequently assembled and disassembled.

[0034] Example:

[0035] Please see Figure 1-3 A parallelism measuring fixture includes a mounting plate 1, a fixing plate 14 fixedly connected to the bottom end of the mounting plate 1, a guide rail 2 detachably connected to one side end of the mounting plate 1, a slider 3 slidably connected to the guide rail 2, a connecting plate 4 fixedly connected to one side end of the slider 3, and a clamping component 5 provided on the connecting plate 4, and the clamping component 5 corresponding to the guide rail 2.

[0036] In this embodiment, the guide rail 2 is mounted on the mounting plate 1, and the mounting plate 1 is fixed in the measurement area by the fixing plate 14. The measuring device is mounted on the connecting plate 4 and moves smoothly through the sliding connection between the slider 3 and the guide rail 2, thereby realizing the measurement of the parallelism of the workpiece. During the measurement process, the slider 3 can be locked by the clamping assembly 5 and the connecting plate 4, so that the slider 3 is stable on the guide rail 2, which facilitates the determination of the measurement results of the measuring device at different positions of the workpiece and prevents the measuring device from slipping and causing damage.

[0037] Specifically, the clamping assembly 5 includes a fixed base 51, a bidirectional screw 52, ​​and two clamping blocks 53. The fixed base 51 is fixedly connected to one end of the connecting plate 4 near the guide rail 2. The bidirectional screw 52 is rotatably connected to the fixed base 51, and one end of the bidirectional screw 52 extends through to one side of the fixed base 51. The two clamping blocks 53 are threaded to the circumferential surface of the bidirectional screw 52, ​​and the two clamping blocks 53 are slidably connected to the fixed base 51 and located on the symmetrical sides of the guide rail 2.

[0038] In this embodiment, when the connecting plate 4 moves the measuring device, the fixed seat 51 moves with the connecting plate 4. After the measuring device stops moving, the two clamping blocks 53 slide within the two fixed seats 51 by rotating the bidirectional screw 52. The circumferential surface of the bidirectional screw 52 is provided with two threads in opposite directions. The two clamping blocks 53 are threadedly connected to the opposite threads on both sides. The rotation of the bidirectional screw 52 can bring the two clamping blocks 53 closer together, thereby clamping and locking the guide rail 2 and stabilizing the measuring device in the current position.

[0039] Specifically, one end of the bidirectional screw 52 is detachably connected to a handle 7, and the handle 7 is located on one side of the fixed base 51.

[0040] In this embodiment, the handle 7 makes it easier to rotate the bidirectional screw 52 and allows the operator to move the measuring device from one side.

[0041] Specifically, rubber blocks 8 are fixedly connected to the adjacent ends of the two clamping blocks 53, and the two rubber blocks 8 correspond to the guide rail 2.

[0042] In this embodiment, when the two clamping blocks 53 are close together, the two rubber blocks 8 will contact the guide rail 2 for clamping and locking. The two rubber blocks 8 are elastic, which can improve the clamping effect and prevent the guide rail 2 from wearing when it is clamped.

[0043] Specifically, one side of the mounting plate 1 is detachably connected to multiple positioning pins 9, and the multiple positioning pins 9 are arranged in a straight line and are all located on one side of the guide rail 2.

[0044] In this embodiment, multiple positioning pins 9 are installed in a straight line on the mounting plate 1, which can position the guide rail 2 on the mounting plate 1 and prevent the guide rail 2 from tilting.

[0045] Specifically, a set of limiting blocks 10 are fixedly connected to the mounting plate 1 and the fixing plate 14, and the set of limiting blocks 10 corresponds to the slider 3. There are two limiting blocks 10 in the set. The two limiting blocks 10 are fixedly connected to the mounting plate 1 and the fixing plate 14 respectively, and the two limiting blocks 10 are located on the upper and lower sides of the guide rail 2 respectively, corresponding to the slider 3.

[0046] In this embodiment, two limiting blocks 10 protect the slider 3 from the top and bottom sides, which can effectively prevent the slider 3 from falling off the guide rail 2 and affecting its use.

[0047] Specifically, a telescopic dust cover 11 is fixedly connected between the top of the slider 3 and the limiting block 10 on the mounting plate 1, and the telescopic dust cover 11 is located on the outside of the guide rail 2.

[0048] In this embodiment, when the slider 3 moves upward, the telescopic dust cover 11 will retract due to the upper limiting block 10. When the parallelism of the workpiece is not measured, the slider 3 will slide down and stop moving due to the restriction of the lower limiting block 10. The telescopic dust cover 11 will then unfold to protect the guide rail 2 as the slider 3 moves.

[0049] Specifically, a reinforcing rib 12 is fixedly connected between one end of the mounting plate 1 and the top end of the fixing plate 14.

[0050] In this embodiment, the reinforcing rib 12 can improve the strength between the mounting plate 1 and the fixing plate 14, and ensure the stability of the tooling fixture structure.

[0051] Specifically, a magnetic base 13 is fixedly connected to the bottom end of the fixing plate 14.

[0052] In this embodiment, the magnetic base 13 enables the fixing plate 14 to be quickly assembled and disassembled in the measurement area, improving the convenience of tooling fixture assembly and disassembly.

[0053] Working principle: The measuring device is installed on the connecting plate 4. When measuring the parallelism of the workpiece, the connecting plate 4 drives the measuring device to move smoothly on the guide rail 2 through the slider 3. During the movement of the measuring device, the position of each segment of the workpiece is measured. When the measuring device needs to stop measuring, it is locked on the guide rail 2 by the clamping component 5 on the connecting plate 4, so that the measuring device can be stably placed in the required position, which is convenient for confirming the measurement results.

[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
