Description

Technical Field

[0001] This utility model relates to the field of V-shaped double-axis guide rail testing technology, and in particular to a support device for testing V-shaped double-axis guide rails. Background Technology

[0002] Currently, in the production and quality control process of V-type dual-axis guide rails, the detection of their precision parameters is a key step to ensure the performance of the guide rails in subsequent assembly and use. As a high-precision transmission component, V-type dual-axis guide rails are widely used in fields such as automation equipment, CNC machine tools, and precision instruments. Their own precision directly determines the stability of equipment operation, positioning accuracy, and service life. Therefore, the support and positioning requirements of the guide rails during the testing process are extremely stringent.

[0003] Among the problems is the lack of a precise pre-positioning structure and large initial placement deviations: existing support devices mostly support the guide rails with simple platforms or brackets, without designing suitable pre-positioning components for the special cross-sectional shape of the V-shaped double-axis guide rails. Before testing, operators need to manually adjust the position of the guide rails on the support device, which is not only time-consuming and laborious, but also makes it difficult to ensure the precise alignment of the guide rail axis with the testing baseline. This can easily lead to systematic errors in the test data due to initial placement deviations, especially for long guide rails.

[0004] Insufficient stability of the clamping mechanism leads to easy displacement and wobbling during testing: Although some support devices are equipped with clamping components, the clamping methods are mostly single-point clamping or uneven lateral compression, and lack a stable guiding structure. During the testing process, when the testing instrument (such as a dial indicator or laser interferometer) contacts and moves against the guide rail surface, the guide rail is easily subjected to external forces, resulting in slight displacement or wobbling. In addition, if the clamping components themselves have problems such as sliding jamming or misalignment, it will further aggravate the instability of the guide rail, causing fluctuations in the test data and failing to accurately reflect the true accuracy level of the guide rail.

[0005] To address this issue, we propose a support device for testing V-shaped dual-axis guide rails. Utility Model Content

[0006] The purpose of this utility model is to solve the problems existing in the prior art by proposing a support device for testing V-shaped double-axis guide rails.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A support device for testing a V-shaped dual-axis guide rail includes: a base on which a pre-installation assembly is fixedly mounted for positioning and assembling the V-shaped dual-axis guide rail; a sliding groove extending through both side walls of the base along its length, wherein a clamping assembly is slidably mounted for laterally clamping and positioning the V-shaped dual-axis guide rail already assembled on the pre-installation assembly; and a drive mechanism located on one side of the clamping assembly, with its power output end connected to the clamping assembly. The drive mechanism is used to push the clamping assembly along the groove towards the side of the V-shaped dual-axis guide rail, thereby creating a counter-clamping force between the clamping assembly and the side wall of the base, and clamping and positioning both ends of the V-shaped dual-axis guide rail.

[0009] Preferably, the pre-installed component includes detachable limiting blocks on both sides of the base, with a slot in the middle of the limiting block that is adapted to a V-shaped dual-axis guide rail.

[0010] Preferably, the clamping assembly includes a slide plate that is slidably mounted in the groove, with a pressing plate fixedly connected to one side of the slide plate and a stop plate provided on the other side of the slide plate.

[0011] Preferably, one end of the slide plate has two rows of several insertion holes, and screws are inserted and installed on both sides of the abutment plate, with the screws corresponding to the insertion holes.

[0012] Preferably, the driving mechanism includes an L-shaped frame disposed on one side of the base, a concave seat fixedly connected to one side of the L-shaped frame, a connecting seat rotatably mounted inside the concave seat, an arc-shaped pressure arm rotatably mounted in the middle of the connecting seat, an extrusion rod rotatably mounted at the other end of the arc-shaped pressure arm, and the other end of the extrusion rod being fixedly connected to the side wall of the extrusion plate.

[0013] Preferably, the bottom two sides of the L-shaped frame are fixedly connected to connecting frames, and the other end of the connecting frame is fixedly connected to the side wall of the base.

[0014] Preferably, a handle is fixedly connected to one side of the connector.

[0015] Preferably, a limiting cylinder is fixedly installed at the middle of the longitudinal end of the L-shaped frame, and the limiting cylinder is slidably connected to the extrusion rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention allows for the preliminary positioning and assembly of the V-shaped dual-axis guide rail via pre-installation components, preventing placement deviations from affecting testing accuracy before inspection. The sliding groove provides a stable sliding guide for the clamping component, which, in conjunction with the drive mechanism, pushes the clamping component closer to the side of the guide rail, creating a counter-clamping force between the clamping component and the base sidewall. This securely clamps both ends of the guide rail, effectively preventing displacement or shaking during inspection and ensuring the accuracy of the test data. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-5 A support device for testing V-shaped dual-axis guide rails includes: a base 1, on which a pre-installation component is fixedly installed, the pre-installation component being used for positioning and assembling the V-shaped dual-axis guide rails;

[0026] The slide groove 2 extends through both sides of the base 1 along the length of the base 1. A clamping assembly is slidably installed in the slide groove 2, and the clamping assembly is used to laterally clamp and position the V-shaped double-axis guide rail that has been assembled on the pre-installed assembly.

[0027] The drive mechanism is located on one side of the clamping assembly, and the power output end of the drive mechanism is connected to the clamping assembly for transmission. The drive mechanism is used to push the clamping assembly along the groove direction of the slide 2 toward the side of the V-shaped double-axis guide rail, so that the clamping assembly and the side wall of the base 1 form a counter-clamping force, thereby clamping and positioning the two ends of the V-shaped double-axis guide rail.

[0028] First, the V-shaped dual-axis guide rail to be tested is placed in the pre-installation assembly on the base 1. The pre-installation assembly uses its own structure to initially limit the guide rail, determining the approximate installation position of the guide rail on the base 1, and completing the initial positioning assembly. Then, according to the actual length of the guide rail, the initial position of the clamping assembly in the slide 2 is adjusted so that the clamping assembly is aligned with the side end of the guide rail. Finally, the drive mechanism is started, and the power output end of the drive mechanism transmits power to the clamping assembly, pushing the clamping assembly to move smoothly along the groove direction of the slide 2 towards the side of the guide rail until the clamping assembly is in close contact with the side of the guide rail. At this time, the clamping assembly and the side wall of the base 1 form a counter-clamping force, firmly clamping the guide rail from both ends, providing stable support and positioning for subsequent testing.

[0029] Furthermore, the pre-installed components include limiting blocks 11 bolted to both sides of the base 1. Both sides of the limiting blocks 11 and the base 1 are fitted with screw holes, and bolts are threaded into the corresponding two screw holes. A slot 12 is provided in the middle of the limiting blocks 11, and the slot 12 is adapted to the V-shaped double-axis guide rail.

[0030] In the pre-testing preparation stage, according to the specifications of the V-shaped dual-axis guide rail to be tested, a limiting block 11 that matches the shape of the guide rail is selected for the central slot 12. The limiting block 11 is fixedly installed at the preset positions on both sides of the base 1 through a detachable connection structure. After installation, the two ends of the guide rail are respectively embedded into the slots 12 of the limiting blocks 11 on both sides. The inner wall of the slot 12 fits tightly with the outer wall of the guide rail. The constraint effect of the slot 12 on the guide rail restricts the deviation of the guide rail in the horizontal and vertical directions, thereby achieving the initial accurate positioning of the guide rail and laying the foundation for the clamping operation of the clamping components. When it is necessary to test guide rails of different specifications, the current limiting block 11 is removed and replaced with a new limiting block 11 of the corresponding slot 12 specification.

[0031] Furthermore, the clamping assembly includes a slide plate 21 that is slidably installed in the slide groove 2, with a pressing plate 22 fixedly connected to one side of the slide plate 21 and a stop plate 23 provided on the other side of the slide plate 21.

[0032] The slide plate 21 is slidably installed in the groove 2 of the base 1, ensuring that the slide plate 21 can only move along the length of the groove 2. The extrusion plate 22 is fixed on the side of the slide plate 21 facing the guide rail and is a clamping component that is in direct contact with the guide rail. When the drive mechanism applies a force to the abutment plate 23, the force is transmitted to the slide plate 21 through the abutment plate 23, pushing the slide plate 21 to slide along the groove 2 towards the guide rail. The slide plate 21 drives the extrusion plate 22 to move synchronously until the extrusion plate 22 contacts the side of the guide rail. As the drive mechanism continues to apply force, the extrusion plate 22 generates a clamping force on the side of the guide rail. At the same time, the slide plate 21 maintains a smooth sliding in the groove 2, preventing the extrusion plate 22 from tilting, and finally achieving uniform clamping of the guide rail.

[0033] A rubber pad is provided on the surface of the abutment plate 23. When the drive mechanism pushes the clamping assembly to clamp the V-shaped double-axis guide rail along the groove direction of the slide groove 2, the rubber pad on the surface of the abutment plate 23 has a buffering effect.

[0034] Furthermore, one end of the slide plate 21 has two rows of several insertion holes 25, and screws 24 are inserted and installed on both sides of the abutment plate 23. The screws 24 correspond to the insertion holes 25, and nuts are threaded to the bottom of the screws 24.

[0035] Two rows of several insertion holes 25 are evenly distributed along the length of the slide plate 21 at one end, providing multiple adjustable installation positions for the abutment plate 23. The screws 24 on both sides of the abutment plate 23 are matched in size and spacing with the insertion holes 25. The screws 24 can be inserted into the insertion holes 25 at different positions to fix the relative position of the abutment plate 23 and the slide plate 21. When it is necessary to adapt to guide rails of different lengths, the screws 24 on both sides of the abutment plate 23 are pulled out, and the abutment plate 23 is moved to a suitable position along the length of the slide plate 21 as required, so that the screws 24 on both sides of the abutment plate 23 are aligned with the corresponding insertion holes 25 on the slide plate 21. Then the screws 24 are inserted into the insertion holes 25 to complete the fixation of the position of the abutment plate 23.

[0036] Furthermore, the drive mechanism includes an L-shaped frame 31 set on one side of the base 1, a concave seat 32 fixedly connected to one side of the L-shaped frame 31, bearings symmetrically installed inside the concave seat 32, a rotating shaft fixedly connected to the inner shaft of the two bearings, the middle of the rotating shaft fixedly connected to the connecting seat 33, the connecting seat 33 rotatably installed inside the concave seat 32, an arc-shaped pressure arm 35 rotatably installed in the middle of the connecting seat 33, an extrusion rod 36 rotatably installed at the other end of the arc-shaped pressure arm 35, grooves are provided on the side wall of the connecting seat 33 and the end of the extrusion rod 36, bearings are symmetrically installed inside the grooves, a rotating shaft fixedly connected to the inner shaft of the two bearings, the two rotating shafts are fixedly connected to the two ends of the arc-shaped pressure arm 35 respectively, and the other end of the extrusion rod 36 is fixedly connected to the side wall of the extrusion plate 22.

[0037] The concave seat 32 is fixed on the L-shaped frame 31, and the connecting seat 33 installed inside it can rotate around its own axis. One end of the arc-shaped pressure arm 35 is rotatably connected to the middle of the connecting seat 33, and the other end is rotatably connected to the pressing rod 36. The other end of the pressing rod 36 is fixedly connected to the pressing plate 22 in the clamping assembly. When an external force is applied to the connecting seat 33, the connecting seat 33 drives the arc-shaped pressure arm 35 to rotate around the rotation axis of the connecting seat 33. The arc-shaped pressure arm 35 pushes the pressing rod 36 to move horizontally through the rotational connection at the other end. Since the pressing rod 36 is fixed to the pressing plate 22, the pressing rod 36 drives the pressing plate 22 to move synchronously, thereby pushing the clamping assembly to move along the guide rail side of the slide groove 2 to achieve clamping of the guide rail. In the entire transmission process, the rotational connection of the connecting seat 33, the arc-shaped pressure arm 35 and the pressing rod 36 forms a continuous power transmission path, which efficiently converts the external force into clamping force.

[0038] After clamping, the guide rail will generate a reverse loosening force on the extrusion plate 22. This force is transmitted to the end of the arc-shaped pressure arm 35 through the extrusion rod 36. Since the line connecting the force point of the arc-shaped pressure arm 35 and the axis of rotation of the connecting seat 33 is perpendicular to the axis of the extrusion rod 36, the torque generated when the reverse force acts on the arc-shaped pressure arm 35 is exactly along the tangent of the circumference of the axis of rotation of the connecting seat 33, and cannot form a torque to push the handle upward. If the handle 34 is not actively pulled upward, the reverse force cannot push the arc-shaped pressure arm 35 to rotate in the opposite direction. The position of the extrusion rod 36 and the clamping assembly will always remain stable, thereby achieving a self-locking effect that can maintain the clamping state without continuous force.

[0039] Furthermore, the bottom two sides of the L-shaped frame 31 are fixedly connected to the connecting frame 3, and the other end of the connecting frame 3 is fixedly connected to the side wall of the base 1.

[0040] When the drive mechanism is working, the force generated by the drive mechanism is transmitted to the L-shaped frame 31. At this time, the connecting frame 3 will provide upward and downward support force to the L-shaped frame 31 and the base 1, limiting the swaying of the L-shaped frame 31 in the horizontal and vertical directions and ensuring that the L-shaped frame 31 always remains in the preset installation position. At the same time, the force borne by the L-shaped frame 31 will be distributed to the side wall of the base 1 through the connecting frame 3, avoiding the force being concentrated at a single connection point between the L-shaped frame 31 and the base 1, reducing the stress load on the connection point, preventing damage to the connection part due to excessive force, thereby ensuring the stable operation of the drive mechanism and the effective transmission of power.

[0041] Furthermore, a handle 34 is fixedly connected to one side of the connector 33.

[0042] The handle 34 is fixed to one side of the connecting seat 33, providing a convenient point for the operator to apply force. When the operator needs to drive the clamping assembly, he / she holds the handle 34 and applies a rotational force. The handle 34 drives the connecting seat 33 to rotate around the rotation axis inside the concave seat 32. The rotation of the connecting seat 33 is converted into the linear movement of the extrusion plate 22 through the transmission of the arc-shaped pressure arm 35 and the extrusion rod 36, which in turn pushes the clamping assembly to clamp the guide rail.

[0043] Furthermore, a limiting cylinder 37 is fixedly installed at the middle of the longitudinal end of the L-shaped frame 31, and the limiting cylinder 37 is slidably connected to the compression rod 36.

[0044] The limiting cylinder 37 is fixedly installed at the middle of the longitudinal end of the L-shaped frame 31. Its internal diameter matches the outer diameter of the extrusion rod 36, allowing the extrusion rod 36 to slide axially within the limiting cylinder 37. When the drive mechanism pushes the extrusion rod 36 to move, the inner wall of the limiting cylinder 37 constrains the extrusion rod 36, limiting its lateral displacement in the horizontal direction and its tilt in the vertical direction. This ensures that the extrusion rod 36 always moves along the preset horizontal direction, thereby ensuring that the extrusion plate 22 moves along the side of the guide rail in a straight line and improving the accuracy of the clamping position. At the same time, if the extrusion rod 36 vibrates due to force during movement, the limiting cylinder 37 will suppress the vibration through the contact between its inner wall and the extrusion rod 36, reducing the impact of vibration on the transmission accuracy of the drive mechanism and the clamping stability of the guide rail.

[0045] 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 the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
