Description

Technical Field

[0001] This application relates to the field of slider machining tooling technology, and in particular to a high-efficiency and high-precision slider positioning device. Background Technology

[0002] As a key component of the linear guide, the machining accuracy of slider 1 directly affects the operational stability and precision of the linear guide; therefore, the machining accuracy of slider 1 is extremely critical. With the surge in market demand, the machining efficiency of slider 1 is equally important.

[0003] During the machining of slider 1, refer to Figure 1 As shown in a, the top mounting hole 17, the end mounting hole 18, and the lower baffle mounting hole 16 need to be machined on the first reference surface 11, the second reference surface 12, the third reference surface 13, and the fourth reference surface 14 of the slider 1, respectively. The first reference surface 11 is the top surface of the slider 1, the second reference surface 12 and the third reference surface 13 are the two end surfaces of the slider 1, and the fourth reference surface 14 is the bottom surface of the slider 1.

[0004] Existing technology, in order to achieve cost-effectiveness, mainly uses a three-axis vertical machining center equipped with ordinary fixtures when machining the mounting holes, requiring four clamping operations to complete the machining of slider 1: (Refer to...) Figure 1 The smaller images b, c, and d in the text Figure 1 In the diagram, small figure b shows the state when machining the top mounting hole 17 on the first reference surface 11, small figure c shows the state when machining the end mounting hole 18 on the second reference surface 12 or the third reference surface 13, and small figure d shows the state when machining the lower baffle mounting hole 16 on the fourth reference surface 14. After machining the top mounting hole 17 at the position shown in small figure b, the slider 1 flips to the position shown in small figure c to machine the end mounting hole 18 on one end surface, then flips 180° to machine the end mounting hole 18 on the other end surface, and finally flips to the position shown in small figure d to machine the lower baffle mounting hole 16.

[0005] The existing processing technology requires four clamping operations, which is cumbersome and results in the accumulation of four errors, making it difficult to guarantee processing accuracy. Utility Model Content

[0006] The technical problem to be solved by this utility model is that the existing technology requires four clamping operations to complete the machining of the four face positions of the slider, and the machining accuracy and efficiency are very low.

[0007] Therefore, this utility model provides a high-efficiency and high-precision positioning device for sliders.

[0008] The technical solution adopted by this utility model to solve its technical problem is:

[0009] A high-efficiency and high-precision positioning device for sliders, comprising,

[0010] A clamping module for clamping a slider;

[0011] A turntable assembly for rotating the clamping module;

[0012] The clamping module includes,

[0013] A positioning base plate, wherein a slider clamping area is provided on the positioning base plate, and an avoidance hole is provided on the positioning base plate, the avoidance hole being opposite to the top surface mounting hole on the slider in the slider clamping area;

[0014] A limiting member is used to limit and clamp the slider within the slider clamping area.

[0015] Furthermore, the limiting component includes an end face limiting block and a pusher, which act on the two end faces of the slider respectively, and cooperate with each other to limit the length direction of the slider.

[0016] Furthermore, the end face limiting block is fixedly mounted on the positioning base plate, and the pusher head is movably mounted on the positioning base plate via a lateral clamping cylinder.

[0017] Furthermore, the lateral clamping cylinder is mounted on the positioning base plate, and a bracket is hinged to the lateral clamping cylinder. There are two hinge points between the bracket and the lateral clamping cylinder, namely a first hinge point and a second hinge point. The first hinge point is the hinge point between the bracket and the cylinder body of the lateral clamping cylinder, and the second hinge point is the hinge point between the bracket and the output end of the lateral clamping cylinder. The second hinge point is located on the side of the first hinge point away from the slider, and the push head is connected to the bracket.

[0018] Furthermore, the positioning base plate is provided with two side limiting plates, which are respectively disposed on both sides of the line connecting the end face limiting block and the lateral clamping cylinder, and a slider clamping area is formed between the two side limiting plates, the end face limiting block, and the lateral clamping cylinder.

[0019] Furthermore, the limiting component also includes two swing cylinders, which are respectively disposed on the side of the side limiting plate away from the slider clamping area. Each swing cylinder is provided with a pressure head, which is adapted to the shape of the first limiting part of the slider.

[0020] Furthermore, air tightness detection is provided on the contact surface between the end face limiting block and the end face of the slider, the contact surface between the side limiting plate and the side wall of the slider, and the contact surface between the positioning base plate and the slider.

[0021] Furthermore, the turntable assembly includes a turntable, a disc tailstock, and two trays. The two trays are rotatably connected to the turntable and the disc tailstock on opposite sides. A drive device is provided on the turntable to drive the trays to rotate. The clamping module is disposed between the two trays.

[0022] Furthermore, multiple clamping modules can be provided between the two trays, and the arrangement direction of the multiple clamping modules is perpendicular to the length direction of the slider.

[0023] Furthermore, a support plate is provided between the two pallets, and a plurality of clamping modules are arranged on the support plate along the length direction of the support plate.

[0024] The beneficial effects of this utility model are as follows: This application installs a slider hydraulic clamp onto a cradle-type four-axis machine. After the slider is positioned, the machining of the mounting holes on the four sides of the slider can be completed by rotating the cradle-type four-axis machine. The machining of all four sides can be completed in one clamping, reducing the number of clamping operations by three compared to the original process, eliminating the errors caused by the three clamping operations, and achieving higher machining accuracy; reducing the number of clamping and rotation operations by three times greatly shortens the machining time, improves machining efficiency, and reduces costs.

[0037] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] A high-efficiency and high-precision positioning device for a slider 1 includes a worktable 2, a base 3, a turntable assembly 4, a support plate 5, and multiple clamping modules 6.

[0039] The turntable assembly 4 is mounted on the worktable 2 via the base 3. The turntable assembly 4 drives the support plate 5 to swing and rotate. Multiple clamping modules 6 are provided and arranged on the support plate 5. The clamping modules are used to fix the clamping slider 1. Thus, the device can fix multiple sliders 1 at the same time, and the orientation of the slider 1 can be adjusted by the turntable assembly 4. The process does not require secondary clamping, which facilitates the machining of mounting holes for the slider 1, thereby achieving efficient and high-precision machining of the slider 1.

[0040] Specifically, the turntable assembly 4 includes a turntable 41, a disc tailstock, and two support plates 43. The turntable 41 and the disc tailstock are mounted on the base 3 along the X-axis. The two support plates 43 are rotatably connected to the turntable 41 and the disc tailstock on opposite sides. The support plate 5 is connected between the two support plates 43. The turntable 41 is equipped with a drive device for driving the support plates 43 and the support plate 5 to rotate.

[0041] The length of the support plate 5 is set along the X-axis, and multiple clamping modules 6 are arranged on the support plate 5 along the X-axis, such as... Figure 3 As shown. Each clamping module 6 includes a positioning base plate 61 and limiting components. The limiting components include an end face limiting block 63, a lateral clamping cylinder 64, and two swing cylinders 67. The end face limiting block 63 and the lateral clamping cylinder 64 are both disposed on the positioning base plate 61 and are arranged opposite to each other. The end face limiting block 63 and the lateral clamping cylinder 64 are arranged along the Y-axis direction (i.e., the length direction of the slider 1), as shown in the figure. Figure 4 A pusher 66 is connected to the side clamping cylinder 64 via a bracket 65. The end face limiting block 63 abuts against one end face of the slider 1. The side clamping cylinder 64 and the pusher 66 act on the other end face of the slider 1. The end face limiting block 63 and the side clamping cylinder 64 cooperate with each other to position the slider 1 along the length direction of the slider 1.

[0042] Specifically, the bracket 65 is hinged to the cylinder body of the lateral clamping cylinder 64 (first hinge point 651), and the output end of the lateral clamping cylinder 64 is hinged to the bracket 65 (second hinge point 652). The second hinge point 652 is located on the side of the first hinge point 651 away from the slider 1, and the push head 66 is connected to the bracket 65. When the slider 1 is clamped in the length direction, as follows... Figure 5 As shown in small figure a, the hydraulic cylinder lifts up, causing the support 65 and push head 66 to rotate toward slider 1, thereby clamping slider 1; when slider 1 is released in the length direction, as ... Figure 5 As shown in small figure b, the hydraulic cylinder falls, causing the bracket 65 and push head 66 to rotate away from the slider 1, thereby releasing the slider 1.

[0043] Two side limiting plates are provided on the positioning base plate 61. The side limiting plates are respectively located on both sides of the line connecting the end face limiting block 63 and the lateral clamping cylinder 64. The side limiting plates 62 are used to initially limit the side wall of the slider 1. The two side limiting plates 62, the end face limiting block 63, and the lateral clamping cylinder 64 form the slider 1 clamping area. Two swing cylinders 67 are respectively located on the side of the side limiting plate 62 away from the slider 1 clamping area. A pressure plate 68 is mounted on the swing cylinder 67, and a pressure head is connected to the pressure plate 68. The corner area between the two opposite sides of the slider 1 and the fourth reference surface 14 is defined as the first limiting part 15. The pressure head adopts a contour design to match the shape of the first limiting part 15 of the slider 1. When the cylinder pulls down, it can provide downward pressure and lateral force. Adjacent swing cylinders 67 in adjacent clamping modules 6 can be staggered to make more reasonable use of the space on the support plate 5. During installation, the lateral clamping cylinder 64 can be embedded in the positioning base plate 61.

[0044] Furthermore, the positioning substrate 61 is provided with a plurality of clearance holes 610. When the slider 1 is located in the slider 1 clamping area, the position of the clearance hole 610 is opposite to the position of the top surface mounting hole 17 on the slider 1.

[0045] Air tightness detectors are provided on the contact surfaces of the end face limiting block 63 and the end face of the slider 1, the contact surfaces between the side limiting plate 62 and the side wall of the slider 1, and the contact surfaces between the positioning base plate 61 and the slider 1. These detectors are used to detect the contact between the end face of the slider 1 and the end face limiting block 63. If the clamping is not good, the air leakage is serious, and the air tightness pressure is insufficient, the machine tool will alarm.

[0046] Furthermore, the workbench 2 is provided with multiple positioning grooves 21 along the horizontal direction. In this embodiment, the length direction of the positioning grooves 21 is set along the X-axis direction, and the multiple positioning grooves 21 are arranged along the Y-axis direction. The base 3 is provided with positioning strips, which are inserted into the positioning grooves 21 at appropriate positions to adjust the position of the base 3 on the workbench 2. The positioning grooves 21 can be set as T-shaped grooves or dovetail grooves to restrict the base 3 from moving in the vertical direction.

[0047] The implementation principle of this application is as follows:

[0048] Before slider 1 is clamped, both swing cylinders 67 and the side clamping cylinder 64 are... Figure 7 As shown in the small diagram (b), the slider is in the released state to facilitate the insertion of slider 1. Slider 1 is placed in the slider 1 clamping area, at which point the fourth reference surface 14 is positioned away from the positioning base plate 61, with the fourth reference surface 14 facing upwards. First, the lateral clamping cylinder 64 rises to clamp slider 1 and then releases it; secondly, the two swing cylinders 67 rotate, causing the pressure block 69 to move to a position above slider 1 opposite to the first limiting part 15 of slider 1, and then pulls down to press slider 1. Figure 7As shown in small figure a; finally, the lateral clamping cylinder 64 rises to clamp slider 1, thus completing the clamping of slider 1. After clamping, the airtightness test begins. If the airtightness test alarms, the above actions need to be repeated. The other three slider 1 clamping modules work on the same principle as this template.

[0049] At this time, the fourth reference surface 14 on slider 1 faces upward and is aligned with the machining lower baffle mounting hole 16, referring to... Figure 2 At this time, the turntable assembly 4 is in the 0° state, and the end face limiting block 63 and push head 66 do not block the position of the end face mounting hole 18 to be processed. The turntable assembly 4 rotates 90° so that one end face faces upward and is connected to the end face mounting hole 18 at one end. By flipping the carrier plate 5 and clamping module 6 by the turntable assembly 4, it rotates to the 180° state so that the side of the positioning base plate 61 away from the slider 1 faces upward, so that the top surface mounting hole 17 can be processed through the clearance hole 610. It rotates again to the 270° state so that the other end face faces upward and is connected to the end face mounting hole 18 at the other end.

[0050] The multiple clamping modules 6 on the support plate 5 of this device can operate independently. When machining mounting holes, the hydraulic clamps of the slider 1 can be rotated 0°, 90°, 270°, and 360° by controlling the turntable 41. This allows for the machining of holes on each mounting surface of the slider 1 in a single clamping operation. This eliminates the need for multiple clamping operations on the slider 1, reducing the cumulative error caused by three clamping operations, improving product machining accuracy, and significantly increasing production efficiency.

[0051] The device is equipped with hydraulic clamps, which reduces manual clamping time, minimizes the impact of human factors, and improves product processing quality; it is also equipped with online airtightness detection to determine clamping accuracy, further improving the yield rate.

[0052] The clamping fixture and airtightness tester are both integrated into the machine tool, laying a solid foundation for automated production.

[0053] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined by the scope of the claims.
