Description

Technical Field

[0001] This application relates to the technical field of linear guide machining, and in particular to a clamping mechanism and clamping method for linear guide machining. Background Technology

[0002] Linear guides can be categorized into: roller linear guides, cylindrical linear guides, and ball linear guides. When machining existing guides on a milling machine, a fixture is required to hold them. By rotating the screw of a single fixture, the screw pushes the clamping plate to hold the guide. To control the guide's level, the operator needs to repeatedly loosen and fine-tune the clamping plate before re-clamping. If even a slight deviation occurs during clamping, the fixture must be loosened again for further fine-tuning until a balanced state is achieved.

[0003] Patent application number 20191110470.1 discloses a clamping mechanism for linear guide rail processing. This solution uses a balancing mechanism to adjust the balance at both ends of the guide rail. One drive shaft drives multiple drive gears to rotate simultaneously, thereby driving multiple sleeves to move synchronously, which in turn drives the clamping plate to clamp the guide rail. Multiple sleeves simultaneously drive the clamping plate to clamp, thus improving clamping stability.

[0004] However, the above solution uses a relatively simple method for fixing the linear guide rail, which is just clamping and fixing. This can easily cause wobbling in other directions, resulting in poor clamping effect. Summary of the Invention

[0005] This application provides a clamping mechanism and clamping method for machining linear guides, which solves the technical problem in the prior art where clamping linear guides often involves clamping and fixing in a single dimension, which easily leads to wobbling in other directions and resulting in poor clamping effect. It achieves limiting in multiple directions and improves the clamping effect.

[0006] This application provides a clamping mechanism for machining linear guides, including:

[0007] A clamping platform is provided with a mounting groove for mounting the linear guide rail to be processed;

[0008] A downward clamping mechanism is used to press and fix the linear guide rail in the vertical direction. The downward clamping mechanism includes several vertical clamping cylinders, the output ends of which point downwards and are connected to vertical clamping rods. The vertical clamping rods are aligned with the centerline of the mounting groove.

[0009] A first follow-up adjustment mechanism is connected to the pressing clamping mechanism. The first follow-up adjustment mechanism is used to adjust the position of the pressing clamping mechanism, thereby changing the distance between the pressing clamping mechanism and the linear guide rail.

[0010] Before the first follow-up adjustment mechanism is activated, the pressing clamping mechanism is used to clamp and fix the linear guide rail before processing. After the first follow-up adjustment mechanism is activated, the pressing clamping mechanism is used to clamp and fix the linear guide rail after processing.

[0011] Furthermore, the first servo adjustment mechanism includes:

[0012] A follower component, connected to the machining mechanism, moves along with the machining mechanism as the machining mechanism moves; and

[0013] A first adjustment component is connected to the pressing and clamping mechanism. A follower component is connected to the first adjustment component. The follower component drives the first adjustment component to move, thereby adjusting the position of the pressing and clamping mechanism.

[0014] Furthermore, the follower component includes:

[0015] A follower guide rail is disposed above the mounting groove;

[0016] A follower slide block, wherein the follower slide block is slidably mounted on the follower guide rail;

[0017] An upper follower rod, connected to the follower slide, and connected to the machining mechanism, moves together with the machining mechanism when it moves; and

[0018] The lower follower rod is connected to the follower slide and is connected to an adjusting rack. The adjusting rack is connected to the first adjusting component in a transmission connection. When the follower slide moves, the first adjusting component is driven.

[0019] Further, the first adjustment component includes:

[0020] A first adjusting plate is vertically disposed on the clamping platform;

[0021] A vertical adjustment slide is provided, and there are several vertical adjustment slides, which are spaced apart on the first adjustment plate.

[0022] A vertically adjustable slide block, wherein the vertically adjustable slide block is vertically slidably disposed in the vertically adjustable slide groove, and a plurality of vertically clamping cylinders correspond one-to-one with a plurality of the vertically adjustable slide grooves, the vertically clamping cylinders being mounted on the vertically adjusting slide blocks corresponding to the vertically adjusting slide grooves; and

[0023] A vertical adjusting screw is provided, which passes through the vertical adjusting groove and is threaded through the vertical adjusting slide block. One end of the vertical adjusting screw extends out of the vertical adjusting groove and is connected to a vertical adjusting gear. The vertical adjusting gear is connected to and driven by the follower component.

[0024] Furthermore, the first follow-up adjustment mechanism also includes a first reverse component, which includes a first reverse rack and a first reverse gear. The first reverse rack is connected to the follow-up component, the first reverse gear meshes with the first reverse rack, and the first reverse gear is connected to the first adjustment component. When the follow-up component is activated, the first reverse rack moves, driving the first reverse gear to rotate, thereby causing the first adjustment component to reverse.

[0025] Another aspect of this application provides a clamping method for machining linear guides, comprising the following steps:

[0026] Step 1: Place the linear guide rail into the mounting slot, ensuring that the centerline of the linear guide rail coincides with the mounting slot;

[0027] Step 2: The clamping mechanism presses down to clamp the linear guide rail.

[0028] Furthermore, during the linear guide machining process, the movement of the machining mechanism drives the follower component to move, and the follower component drives the first adjustment component to move, causing the output end of the pressing clamping mechanism near the machining mechanism to retract, so as to avoid affecting the machining process.

[0029] Furthermore, the action of the processing mechanism drives the first reverse component to move, causing the output end of the retracted pressing clamping mechanism to extend again.

[0030] The technical solution provided in this application has at least the following technical effects or advantages:

[0031] 1. When machining linear guides, holes need to be drilled on the surface. In this embodiment, the clamping position of the pressing clamping mechanism is the same as the hole position. Before drilling, the pressing clamping mechanism clamps the upper surface of the linear guide. After drilling, the pressing clamping mechanism clamps the bottom of the hole. At the same time, the output end of the pressing clamping mechanism is equivalent to the hole diameter. After the output end of the pressing clamping mechanism is inserted into the hole, it can limit the linear guide and prevent the linear guide from shaking in other directions, thereby achieving a better clamping and positioning effect.

[0032] 2. Because a pressing clamping mechanism and a first follow-up adjustment mechanism are adopted, when the processing mechanism is performing processing, the movement of the processing mechanism drives the pressing clamping mechanism through the first follow-up adjustment mechanism. The output end of the pressing clamping mechanism near the processing area retracts, thereby avoiding interference with the operation of the processing mechanism. Attached Figure Description

[0046] This application discloses a clamping mechanism and clamping method for machining linear guides. When machining linear guides, holes need to be drilled on the surface. In this embodiment, the clamping position of the pressing clamping mechanism 2 is the same as the hole position. Before drilling, the pressing clamping mechanism 2 clamps the upper surface of the linear guide. After drilling, the pressing clamping mechanism 2 clamps the bottom of the hole. Simultaneously, the output end of the pressing clamping mechanism 2 is approximately equal to the hole diameter. After the output end of the pressing clamping mechanism 2 is inserted into the hole, a better clamping and positioning effect can be achieved. Furthermore, due to the use of the pressing clamping mechanism 2 and the first follow-up adjustment mechanism 3, when the machining mechanism is performing machining, the movement of the machining mechanism is driven by the first follow-up adjustment mechanism 3, causing the output end of the pressing clamping mechanism 2 near the machining area to retract, thereby avoiding interference with the movement of the machining mechanism.

[0047] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0048] Example 1

[0049] Reference Figures 1 to 6 This embodiment provides a clamping mechanism for machining linear guides, including a clamping platform 1, a pressing clamping mechanism 2, and a first follower adjustment mechanism 3. The clamping platform 1 is provided with a mounting groove 101 for mounting the linear guide to be machined. The pressing clamping mechanism 2 is used to press and fix the linear guide in the vertical direction. The first follower adjustment mechanism 3 is connected to the pressing clamping mechanism 2 and is used to adjust the position of the pressing clamping mechanism 2, thereby changing the distance between the pressing clamping mechanism 2 and the linear guide. Before the first follower adjustment mechanism 3 is activated, the pressing clamping mechanism 2 is used to clamp and fix the linear guide before machining. After the first follower adjustment mechanism 3 is activated, the pressing clamping mechanism 2 is used to clamp and fix the linear guide after machining.

[0050] Among them, reference Figure 1 and Figure 2 The pressing and clamping mechanism 2 includes several vertical clamping cylinders 201. The output end of the vertical clamping cylinder 201 is vertically downward and connected to a vertical clamping rod 202. The vertical clamping rod 202 is directly opposite the center line of the mounting groove 101.

[0051] Furthermore, referring to Figure 1 The first follow-up adjustment mechanism 3 includes a follow-up component 31 and a first adjustment component 32. The follow-up component 31 is connected to the processing mechanism. When the processing mechanism moves, the follow-up component 31 moves together with it. The first adjustment component 32 is connected to the pressing and clamping mechanism 2. The follow-up component 31 is connected to the first adjustment component 32. The follow-up component 31 drives the first adjustment component 32 to move, thereby adjusting the position of the pressing and clamping mechanism 2.

[0052] Specifically, refer to Figure 3 and Figure 5 The follower component 31 includes a follower guide rail 311, a follower slide 312, an upper follower rod 313, and a lower follower rod 314. The follower guide rail 311 is disposed above the mounting groove 101. The follower slide 312 is slidably disposed on the follower guide rail 311. The upper follower rod 313 is connected to the follower slide 312 and is connected to the processing mechanism. When the processing mechanism moves, the upper follower rod 313 moves together with it. The lower follower rod 314 is connected to the follower slide 312 and is connected to an adjusting rack 315. The adjusting rack 315 is connected to the first adjusting component 32 in a transmission connection. When the follower slide 312 moves, the first adjusting component 32 is driven.

[0053] Specifically, refer to Figure 4 , Figure 5 and Figure 6 The first adjustment assembly 32 includes a first adjustment plate 321, a vertical adjustment slide 322, a vertical adjustment slide block 323, and a vertical adjustment screw 324. The first adjustment plate 321 is vertically mounted on the clamping platform 1. There are several vertical adjustment slides 322, which are spaced apart on the first adjustment plate 321. The vertical adjustment slide block 323 is vertically slidably mounted in the vertical adjustment slides 322. Several vertical clamping cylinders 201 are connected to several vertical adjustment slides 322. In a corresponding configuration, the vertical clamping cylinder 201 is installed on the vertical adjusting slide block 323 in the corresponding vertical adjusting slide groove 322. The vertical adjusting screw 324 passes through the vertical adjusting slide groove 322 and is threaded through the vertical adjusting slide block 323. One end of the vertical adjusting screw 324 extends out of the vertical adjusting slide groove 322 and is connected to the vertical adjusting gear 325. The vertical adjusting gear 325 is connected to the adjusting rack 315 in the follower assembly 31 and is driven by the follower assembly 31.

[0054] When the processing mechanism moves, the adjusting rack 315 also moves, thereby driving the vertical adjusting gear 325 to rotate, driving the first adjusting component 32 to move, causing the position of the vertical clamping cylinder 201 to change, and adjusting the distance between the vertical clamping cylinder 201 and the linear guide rail.

[0055] Furthermore, referring to Figure 4The first follower adjustment mechanism 3 also includes a first reverse component 33, which includes a first reverse rack 331 and a first reverse gear 332. The first reverse rack 331 is connected to the lower follower rod 314 in the follower component 31, and the first reverse gear 332 meshes with the first reverse rack 331. The first reverse gear 332 is connected to the vertical adjustment gear 325 in the first adjustment component 32 via a synchronous belt (not shown). When the follower component 31 moves, the first reverse rack 331 moves, driving the first reverse gear 332 to rotate, thereby causing the first adjustment component 32 to move in the opposite direction.

[0056] The first reverse rack 331 and the adjusting rack 315 are spaced apart, with the first reverse rack 331 located behind the adjusting rack 315. When the machining mechanism moves, the adjusting rack 315 first contacts the vertical adjusting gear 325. At this time, there is no contact between the first reverse rack 331 and the first reverse gear 332. As the machining mechanism moves, the adjusting rack 315 drives the vertical adjusting gear 325 to rotate, causing the vertical clamping cylinder 201 at the front of the machining mechanism to move away from the linear guide rail. The output end of the vertical clamping cylinder 201 also disengages from the linear guide rail. At this time, the output end of the vertical clamping cylinder 201 is not on the path of the machining mechanism and will not obstruct its movement or machining actions.

[0057] After the processing mechanism passes the position of the vertical clamping cylinder 201, the adjusting rack 315 disengages from the vertical adjusting gear 325, and the first reverse rack 331 contacts the first reverse gear 332. As the processing mechanism moves forward, the first reverse rack 331 drives the first reverse gear 332 to move, so that the vertical clamping cylinder 201 in front of the processing mechanism approaches the linear guide rail, and the output end of the vertical clamping cylinder 201 also approaches and presses against the linear guide rail.

[0058] With the aforementioned pressing clamping mechanism 2 and first follow-up adjustment mechanism 3, when the processing mechanism is performing processing, the output end of the pressing clamping mechanism 2 in the processing area retracts, thereby avoiding interference with the operation of the processing mechanism. After the processing mechanism is moved away, the pressing clamping mechanism 2 can press and fix the linear guide rail again.

[0059] It should be noted that when machining linear guides, holes need to be drilled on the surface. The clamping position of the pressing clamping mechanism 2 is the same as the hole position. Before drilling, the pressing clamping mechanism 2 clamps on the upper surface of the linear guide. After drilling, the pressing clamping mechanism 2 clamps at the bottom of the hole. At the same time, the output end of the pressing clamping mechanism 2 is equivalent to the hole diameter. After the output end of the pressing clamping mechanism 2 is inserted into the hole, a better clamping and positioning effect can be achieved.

[0060] Based on this, in this embodiment, the length of the first reverse rack 331 is greater than the length of the adjusting rack 315, so that when the vertical clamping cylinder 201 retracts and then extends, it will exceed the starting position, thus matching the bottom position of the hole after it is opened.

[0061] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0062] When machining linear guides, holes need to be drilled on the surface. In this embodiment, the clamping position of the pressing clamping mechanism 2 is the same as the hole position. Before drilling, the pressing clamping mechanism 2 clamps on the upper surface of the linear guide. After drilling, the pressing clamping mechanism 2 clamps at the bottom of the hole. At the same time, the output end of the pressing clamping mechanism 2 is equivalent to the hole diameter. After the output end of the pressing clamping mechanism 2 is inserted into the hole, a better clamping and positioning effect can be achieved.

[0063] Meanwhile, through the pressing clamping mechanism 2 and the first follow-up adjustment mechanism 3, when the processing mechanism is processing, the output end of the pressing clamping mechanism 2 in the processing area retracts, thereby avoiding interference with the operation of the processing mechanism.

[0064] Example 2

[0065] Reference Figures 1 to 6 This embodiment provides a clamping method for machining linear guides, including the following steps:

[0066] Step 1: Place the linear guide rail into the mounting groove 101 and adjust the position of the linear guide rail so that the center line of the linear guide rail coincides with the mounting groove 101.

[0067] Step 2: The downward clamping mechanism 2 is activated to clamp the linear guide rail;

[0068] Furthermore, during the linear guide machining process, the movement of the machining mechanism drives the follower component 31 to move, and the follower component 31 drives the first adjustment component 32 to move, causing the output end of the pressing clamping mechanism 2 near the machining mechanism to retract, so as to avoid affecting the machining process.

[0069] Furthermore, the action of the processing mechanism drives the first reverse component 33 to move, causing the output end of the retracted pressing clamping mechanism 2 to extend again and clamp the linear guide rail again.

[0070] In summary, in this embodiment, the clamping position of the pressing clamping mechanism 2 is the same as the opening position. Before the opening, the pressing clamping mechanism 2 is clamped on the upper surface of the linear guide rail, and after the opening, the pressing clamping mechanism 2 is clamped at the bottom of the hole. At the same time, the output end of the pressing clamping mechanism 2 is equivalent to the hole diameter. After the output end of the pressing clamping mechanism 2 is inserted into the hole, a better clamping and positioning effect can be achieved.

[0071] Meanwhile, through the pressing clamping mechanism 2 and the first follow-up adjustment mechanism 3, when the processing mechanism is processing, the output end of the pressing clamping mechanism 2 in the processing area retracts, thereby avoiding interference with the operation of the processing mechanism.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
