Description

Technical Field

[0001] This application relates to the technical field of machining, and more particularly to a rapid positioning device for machining. Background Technology

[0002] In machining, linear guides are widely used to fix and control the movement of workpieces. In existing linear guides, when it is necessary to position the slider on the guide rail, it is often done by directly using a bolt mounted on the slider and abutting against the surface of the guide rail. By tightening the bolt, one end of the bolt is pressed against the surface of the guide rail to fix the slider. However, the part of the guide rail that contacts the end of the bolt will be subjected to great pressure, which can easily cause deformation and damage to the guide rail, resulting in the slider not sliding smoothly on the guide rail. Utility Model Content

[0003] This application provides a rapid positioning device for machining, which can improve the technical problem in the related art where the bolts used to fix the slider can easily damage the guide rail.

[0004] This application provides a rapid positioning device for machining, including a guide rail, a slider, and a locking mechanism. The slider has a mating groove and a mounting groove. The guide rail passes through the slider and is slidably connected to the slider through the mating groove. The locking mechanism includes a pair of locking blocks and a locking assembly. The locking blocks have a first sliding groove that mates with the guide rail. The locking blocks are symmetrically arranged inside the mounting groove. The locking blocks are located on both sides of the guide rail and are slidably connected to the guide rail through the first sliding groove. The locking assembly is disposed on the slider and is used to apply a pushing force to the locking blocks to press them firmly onto the guide rail.

[0005] The technical solutions described above in this application embodiment have at least the following technical effects: When the locking assembly does not apply a pushing force to the locking blocks, the slider can drive the two locking blocks to slide freely on the guide rail. When it is necessary to fix the slider, the slider is moved to the position where it needs to be fixed, and then the locking assembly applies a pushing force to the two locking blocks to press them onto the guide rail, thereby increasing the friction between the locking blocks and the guide rail, thus fixing the locking blocks and the slider onto the guide rail. When it is necessary to release the slider, the locking assembly stops applying pressure to the locking blocks. Since the contact surface between the locking blocks and the guide rail is large, the pressure applied by the locking blocks to the guide rail surface when the slider is fixed can be evenly distributed on the contact surface of the two, which can avoid deformation of the guide rail surface due to pressure concentration and can protect the guide rail.

[0006] The rapid positioning device for processing provided in this application uses a locking block with a larger contact area with the guide rail to position the slider, which can avoid deformation of the guide rail surface due to pressure concentration.

[0007] In some embodiments, the locking assembly includes an abutment plate, a transmission member, and a locking member. A second groove is provided on the side of the locking block away from the guide rail. The abutment plate is slidably disposed inside the second groove. The locking member is disposed on the slider and is used to apply pressure to the abutment plate to press it against the locking block. The transmission member is disposed inside the second groove and is used to transmit the pressure of the abutment plate on the locking block.

[0008] In some embodiments, the locking element includes a locking bolt, one end of which passes through the side of the slider and abuts against the side of the abutment plate away from the guide rail, and the locking bolt is threadedly connected to the slider.

[0009] In some embodiments, a handle is fixedly provided on the side of the locking bolt away from the abutment plate.

[0010] In some embodiments, the transmission component is provided in multiple sets. The transmission component includes a sleeve, a spring, and a piston. One end of the sleeve is fixedly connected to the inner wall of the second slide groove. The spring is disposed inside the sleeve. One end of the piston is slidably connected inside the sleeve, and the other end abuts against the side of the abutment plate near the guide rail. The two ends of the spring abut against the piston and the locking block, respectively.

[0011] In some embodiments, guide grooves are provided at both ends of the abutment plate, and guide strips are provided on the inner wall of the second sliding groove, the guide strips being slidably connected inside the guide grooves. Attached Figure Description

[0019] Based on this, in order to improve the technical problem that the bolts used to fix the slider in the related art are prone to damage to the guide rail, the embodiments of this application provide the following solution.

[0020] The following combination Figures 1-5 The present invention will be described in further detail below.

[0021] This embodiment discloses a rapid positioning device for processing: it includes a guide rail 1, a slider 2, and a locking mechanism. The slider 2 has a mating groove 21 and a mounting groove 22. The guide rail 1 passes through the slider 2 and is slidably connected to the slider 2 through the mating groove 21. The locking mechanism includes a pair of locking blocks 3 and a locking assembly. The locking blocks 3 have a first sliding groove 31 that mates with the guide rail 1. The locking blocks 3 are symmetrically arranged inside the mounting groove 22. The locking blocks 3 are located on both sides of the guide rail 1 and are slidably connected to the guide rail 1 through the first sliding groove 31. The locking assembly is arranged on the slider 2 and is used to apply a pushing force to the locking blocks 3 to press them onto the guide rail 1.

[0022] As can be seen from the above, the quick positioning device for processing provided in this application embodiment allows the slider 2 to drive the two locking blocks 3 to slide freely on the guide rail 1 when the locking assembly does not apply a pushing force to the locking block 3. When it is necessary to fix the slider 2, the slider 2 is moved to the position where it needs to be fixed, and then the locking assembly applies a pushing force to the two locking blocks 3 to press them onto the guide rail 1, thereby increasing the friction between the locking block 3 and the guide rail 1, thus fixing the locking block 3 and the slider 2 onto the guide rail 1. When it is necessary to release the fixation of the slider 2, the locking assembly stops applying pressure to the locking block 3. Since the contact surface between the locking block 3 and the guide rail 1 is large, the pressure applied by the locking block 3 to the surface of the guide rail 1 when the slider 2 is fixed can be evenly distributed on the contact surface of the two, which can avoid deformation of the surface of the guide rail 1 due to pressure concentration, and can protect the guide rail 1.

[0023] In some embodiments, please refer to the following: Figures 2 to 5 The locking assembly includes an abutment plate 41, a transmission component, and a locking component. A second groove 32 is provided on the side of the locking block 3 away from the guide rail 1. The abutment plate 41 is slidably disposed inside the second groove 32. The locking component is disposed on the slider 2 and is used to apply pressure to the abutment plate 41 to press it against the locking block 3. The transmission component is disposed inside the second groove 32 and is used to transmit the pressure of the abutment plate 41 on the locking block 3.

[0024] With this setup, when it is necessary to fix the slider 2, pressure is applied to the abutment plate 41 through the locking component, and the abutment plate 41 then applies pressure to the locking block 3 through the transmission component, thereby pressing the locking block 3 onto the guide rail 1 and completing the fixation of the slider 2.

[0025] Optionally, in some embodiments, please refer to Figure 2 and Figure 3 The locking component includes a locking bolt 43, one end of which passes through the side of the slider 2 and abuts against the side of the abutment plate 41 away from the guide rail 1. The locking bolt 43 is threadedly connected to the slider 2.

[0026] With this setup, when the slider 2 needs to be fixed, the locking bolt 43 is turned to press it against the abutment plate 41, which can apply pressure to the abutment plate 41 to press the locking block 3. When it is necessary to release the fixation of the slider 2, the locking bolt 43 is turned in the opposite direction to stop applying pressure to the abutment plate 41.

[0027] Optionally, please refer to Figure 1 A handle 431 is fixedly provided on the side of the locking bolt 43 away from the abutment plate 41.

[0028] With this design, the handle 431 allows the user to easily tighten the locking bolt 43.

[0029] In some embodiments, please refer to Figures 2 to 5 The transmission components are provided in multiple sets, including a sleeve 421, a spring 422 and a piston 423. One end of the sleeve 421 is fixedly connected to the inner wall of the second slide groove 32. The spring 422 is located inside the sleeve 421. One end of the piston 423 is slidably connected inside the sleeve 421, and the other end abuts against the side of the abutment plate 41 near the guide rail 1. The two ends of the spring 422 abut against the piston 423 and the slider 2 respectively.

[0030] With this configuration, multiple sets of transmission components are evenly arranged inside the second slide groove 32. When the locking member applies pressure to the abutment plate 41, the abutment plate 41 slides into the second slide groove 32 and pushes each piston 423. The piston 423 gradually compresses the spring 422, thereby gradually increasing the pressure applied by each spring 422 to the locking block 3 and pressing the locking block 3 onto the guide rail 1. This allows the user to better adjust the amount of pressure applied by the locking block 3 to the guide rail 1.

[0031] Optionally, in some embodiments, please refer to Figure 5 Both ends of the abutment plate 41 are provided with guide grooves 411, and the inner wall of the second sliding groove 32 is provided with guide strips 5, which are slidably connected inside the guide grooves 411.

[0032] With this configuration, the guide bar 5 can limit the position of the abutment plate 41. When the locking member applies pressure to the abutment plate 41 and makes it slide into the second slide groove 32, it prevents the position of the abutment plate 41 from shifting, which would cause uneven pressure on each piston 423 and thus uneven pressure on the surface of the guide rail 1 caused by the locking block 3.

[0033] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
