Description

Technical Field

[0001] This application relates to the field of mechanical equipment technology, and in particular to a swing head auxiliary linear guide clamping structure and machine tool processing equipment. Background Technology

[0002] To meet the machining requirements of complex workpieces at different angles, the role of swivel heads in machine tool processing equipment is becoming increasingly important. Currently, some swivel head structures on existing machine tool processing equipment have auxiliary linear guides. The swivel head and its connecting slider slide along the linear guides, causing the swivel head to move left and right at an angle in conjunction with rotation to machine complex workpieces. However, due to prolonged cutting of workpieces made of very hard materials, coupled with the weight of the spindle installed inside the swivel head and the tools mounted on it, the load on the linear guides and sliders becomes excessive. This leads to machining runout during workpiece processing, affecting the stability of the workpiece machining. Therefore, improving the stability of workpiece machining has become an urgent problem to be solved. Summary of the Invention

[0003] The main technical problem this application addresses is to provide a tilting head auxiliary linear guide clamping structure and machine tool processing equipment that can improve the stability of workpiece processing.

[0004] To solve the above-mentioned technical problems, the first aspect of this application provides a sway head auxiliary rail clamping structure, disposed on the side of the sway head near the slide block. The sway head auxiliary rail clamping structure includes: a movable component, including a first roller and a movable block; wherein the slide block is slidably connected to the sway head, and the slide block has a recess on its side wall at the connection point, the first roller is disposed on the movable block, and the first roller fits against the inner wall of the slide block at the recess; a sliding component, including a second roller and a fixed block; wherein the second roller is disposed on the fixed block, the... The second roller is attached to the outer wall of the slide at the recessed portion, the fixed block is fixed to the swing head, located above the movable block, and the fixed block has a corresponding support point. The fixed block is connected to the movable block through the support point. The drive assembly is movably connected to the movable assembly and has an oil inlet. When hydraulic oil is drawn from the oil inlet, the drive assembly presses down on the movable block, and the movable block moves with the support point as a lever, so that the first roller abuts against the inner wall of the slide at the recessed portion.

[0005] The movable block has a first through hole, and the fixed block has a second through hole. The driving assembly includes: a pin that passes through the first through hole on the movable block and the second through hole on the fixed block; and a locking pin located at one end of the pin near the movable block. When hydraulic oil is drawn from the oil inlet, the pin presses down on the locking pin, causing the locking pin to drive the movable block to perform lever movement around the support point.

[0006] The drive assembly further includes an elastic element sleeved on the pin and located between the movable block and the fixed block. When hydraulic oil is drawn from the oil inlet, the elastic element is in a normal state. When hydraulic oil is replenished from the oil inlet, the pressure of the hydraulic oil lifts the pin, the elastic element is in a compressed state, and the pin lifts the locking pin, so that the locking pin drives the movable block to perform lever movement around the support point, and the first roller disengages from the inner wall of the slide at the recess.

[0007] The oscillating head auxiliary rail clamping structure further includes a sealing assembly, comprising a first seal and a second seal; wherein the first seal and the second seal form a sealed space, and the sealed space stores the hydraulic oil.

[0008] The sway head auxiliary rail clamping structure further includes: an external hydraulic device for drawing and replenishing the hydraulic oil; and an oil pipe, one end of which is connected to the external hydraulic device and the other end of which is connected to the oil inlet.

[0009] The ratio of the distance from the support point to the side surface of the swing head near the slide to the distance from the outer wall of the slide away from the recess to the side surface of the swing head near the slide is in the range of 1 / 4 to 1 / 2.

[0010] To solve the above-mentioned technical problems, a second aspect of this application provides a machine tool processing device, including: a slide; a swivel head rotatably connected to the slide; a slide rail assembly including a linear guide and a slider, the linear guide being disposed on the surface of the slide near the swivel head, the slider being fixed to the swivel head and slidably disposed on the linear guide; and a swivel head auxiliary linear guide clamping structure as described in any of the first aspects above being disposed on the swivel head.

[0011] The surface of the swing head near the slide is provided with a receiving portion, and the swing head auxiliary rail clamping structure is provided at the receiving portion.

[0012] The number of sliders is two, the linear guide is curved, and the swing head auxiliary linear guide clamping structure is located below the linear guide and in the middle of the two sliders, and is stationary relative to the two sliders.

[0013] The machine tool processing equipment further includes: a spindle, which is sleeved inside the oscillating head and used to install cutting tools and process the workpiece to be processed.

[0014] The beneficial effects of this application are as follows: Unlike the prior art, in the sway head auxiliary linear guide clamping structure proposed in this application, when the sway head is in normal processing state, hydraulic oil is drawn from the oil inlet to drive the component to press down the movable block. The movable block moves with the support point on the fixed block as a lever, so that the first roller abuts against the inner wall of the slide in the recess. When the sway head swings left and right, the first roller rolls on the inner wall of the slide in the recess, and the second roller rolls on the outer wall away from the slide in the recess. The friction loss is small, which can reduce the load on the linear guide and the slider, and improve the service life of the linear guide and the slider. Furthermore, by having the first roller clamp against the inner wall of the slide in the recess, the rigidity of the overall structure can be improved, effectively preventing the workpiece from jumping, thereby improving the stability of workpiece processing.

[0025] Please see Figure 1 , Figure 1 This is a schematic diagram of one embodiment of an existing machine tool processing device. The existing machine tool processing device (not shown) includes a slide rail assembly 5, a processing slide block, and a processing swing head connected to the slide rail assembly. The slide rail assembly 5 includes a linear guide rail 50 and a slider 51. The processing slide block is connected to the linear guide rail 50 and is located at... Figure 1 On the right side of the centerline rail 50, the oscillating head is machined and connected to the slider 51, located at... Figure 1 To the left of the slider 51, which is slidably mounted on the linear guide 50, the existing machine tool processing device also includes a spindle 6, which is installed inside the machining head. Because the spindle 6 cuts workpieces made of very hard materials for extended periods, the weight of the spindle 6 installed inside the machining head and the cutting tool (not shown) mounted on it causes excessive load on the linear guide 50 and the slider 51, resulting in machining vibration during workpiece processing and affecting the stability of the workpiece processing.

[0026] To address the problems of the prior art, this application provides the following embodiments, which are described in detail below.

[0027] Please see Figure 2 and Figure 3 , Figure 2 This is a cross-sectional schematic diagram of one embodiment of the oscillating head auxiliary linear guide clamping structure of this application. Figure 3 yes Figure 2 A partially enlarged schematic diagram of the structure in region A. The oscillating head auxiliary rail clamping structure 2 proposed in this application is disposed on the side of the oscillating head 4 near the slide block 3. The oscillating head auxiliary rail clamping structure 2 includes: a movable component 20, a sliding component 21, and a driving component 22. The movable component 20 includes a first roller 200 and a movable block 201. The slide block 3 is slidably connected to the oscillating head 4, and the slide block 3 has a recess 30 on the side wall at the connection point. The first roller 200 is disposed on the movable block 201, and the first roller 200 fits against the inner wall of the slide block 3 at the recess 30 (not shown in the figure). The sliding component 21 includes a second roller 210 and a fixed block 211. The second roller 210 is disposed on the fixed block 211. The second roller 210 is attached to the outer wall of the slide 3 at the recess 30 (not shown in the figure). The fixed block 211 is fixed on the swing head 4 and located above the movable block 201. The fixed block 211 has a corresponding support point 2110. The fixed block 211 is connected to the movable block 201 through the support point 2110. The drive assembly 22 is connected to the movable assembly 20. The drive assembly 22 is provided with an oil inlet 24. When hydraulic oil is drawn from the oil inlet 24, the drive assembly 22 presses down on the movable block 201. The movable block 201 makes a lever movement with the support point 2110 so that the first roller 200 abuts against the inner wall of the slide 3 at the recess 30.

[0028] Specifically, the swing head auxiliary rail clamping structure 2 is composed of multiple components and is located on the side of the swing head 4 near the slide block 3. It includes a movable component 20, a sliding component 21, and a drive component 22. The slide block 3 is slidably connected to the swing head 4, and the slide block 3 has a recess 30 on the side wall at the connection point. The first roller 200 is embedded in the movable block 201, and the first roller 200 fits against the inner wall of the slide block 3 at the recess 30.

[0029] Furthermore, the sliding assembly 21 includes a second roller 210 and a fixed block 211. The second roller 210 is embedded in the fixed block 211 and conforms to the outer wall of the slide 3 at the recess 30. The fixed block 211 is fixed on the swing head 4, located above the movable block 201, and has a corresponding support point 2110. The fixed block 211 is connected to the movable block 201 through the support point 2110. The drive assembly 22 is movably connected to the movable assembly 20 and is used to drive the movable assembly 20. The drive assembly 22 is provided with an oil inlet 24. When hydraulic oil is drawn from the oil inlet 24, the drive assembly 22 presses down on the movable block 201. The movable block 201 will make lever movement with the support point 2110, thereby causing the first roller 200 to abut against the inner wall of the slide 3 at the recess 30. During normal processing of the swing head 4, the rigidity of the overall structure is improved, ensuring smooth processing operation.

[0030] In some implementation scenarios, an external hydraulic device is used to connect an oil pipe (not shown) and a connector (not shown) to the oil inlet 24. Hydraulic oil is drawn from the oil inlet 24, so that the drive assembly 22 can press down the movable block 201. Then the movable block 201 uses the support point 2110 on the fixed block 211 to make lever movement, ensuring that the first roller 200 abuts against the inner wall of the slide 3 at the recess 30.

[0031] In some implementation scenarios, the fixing block 211 is fixedly connected to the swing head 4 by welding, thereby improving the stability of the structure. Of course, in other implementation scenarios, the fixing block 211 can also be fixedly connected to the swing head 4 by threaded connection, thereby improving the portability of disassembly.

[0032] In the oscillating head auxiliary linear guide clamping structure 2 proposed in this application, when the oscillating head 4 is in normal processing state, hydraulic oil is drawn from the oil inlet 24, and the drive assembly 22 presses down the movable block 201. The movable block 201 makes lever movement with the support point 2110 on the fixed block 211, so that the first roller 200 abuts against the inner wall of the slide 3 at the recess 30. When the oscillating head 4 swings left and right, the first roller 200 will roll on the inner wall of the slide 3 at the recess 30, and the second roller 210 will roll on the outer wall away from the slide 3 at the recess 30. The friction loss is small, which can reduce the load on the linear guide 50 and the slider 51, and improve the service life of the linear guide 50 and the slider 51. Furthermore, by having the first roller 200 hook against the inner wall of the slide 3 at the recess 30, the rigidity of the overall structure can be improved, effectively preventing the workpiece from jumping, thereby improving the stability of workpiece processing.

[0033] Please continue reading. Figure 2 and Figure 3In one embodiment, the movable block 201 is provided with a first through hole (not shown in the figure), and the fixed block 211 is provided with a second through hole (not shown in the figure). The drive assembly 22 includes a pin 220 and a locking pin 221. The pin 220 passes through the first through hole on the movable block 201 and the second through hole on the fixed block 211. The locking pin 221 is located at one end of the pin 220 near the movable block 201. When hydraulic oil is drawn from the oil inlet 24, the pin 220 presses down on the locking pin 221, so that the locking pin 221 drives the movable block 201 to make lever movement around the support point 2110.

[0034] Specifically, the pin 220 passes through the first through hole and the second through hole, so that the movable block 201 and the fixed block 211 are both sleeved on the pin 220. The locking pin 221 is set at the end of the pin 220 near the movable block 201. When hydraulic oil is drawn from the oil inlet 24, the pin 220 will press down the locking pin 221, so that the locking pin 221 drives the movable block 201 to make lever movement with the support point 2110 on the fixed block 211, ensuring that the first roller 200 abuts against the inner wall of the slide 3 at the recess 30.

[0035] In one implementation scenario, please refer to Figure 4 and Figure 5 , Figure 4 This is a cross-sectional structural schematic diagram of another embodiment of the oscillating head auxiliary linear guide clamping structure of this application. Figure 5 yes Figure 4 A partially enlarged schematic diagram of the structure in region B. The drive assembly 22 also includes an elastic element 222, which is sleeved on the pin 220 and located between the movable block 201 and the fixed block 211. When hydraulic oil is drawn from the oil inlet 24, the elastic element 222 is in a normal state. When hydraulic oil is replenished from the oil inlet 24, the pressure of the hydraulic oil lifts the pin 220, the elastic element 222 is in a compressed state, and the pin 220 lifts the locking pin 221, so that the locking pin 221 drives the movable block 201 to make lever movement around the support point 2110, and the first roller 200 disengages from the inner wall of the slide 3 at the recess 30.

[0036] Specifically, the elastic element 222 is a compression spring, sleeved on the pin 220, and located between the movable block 201 and the fixed block 211. When hydraulic oil is drawn from the oil inlet 24, the compression spring is in normal condition. When hydraulic oil is replenished from the oil inlet 24, the pressure of the hydraulic oil will increase, causing the pin 220 to rise, the compression spring to tighten, and the locking pin 221 to lift, driving the movable block 201 to make lever movement around the support point 2110, causing the first roller 200 to disengage from the inner wall of the slide block 3 at the recess 30. This facilitates regular maintenance of the swing head auxiliary guide clamping structure 2, thereby further improving the rigidity of the overall structure and ensuring smooth operation when processing workpieces.

[0037] In one implementation, please refer to... Figure 2 and Figure 3 The oscillating head auxiliary rail clamping structure 2 proposed in this application also includes a sealing component 23, including a first seal 230 and a second seal 231; wherein the first seal 230 and the second seal 231 form a sealed space, and the hydraulic oil is stored in the sealed space.

[0038] Specifically, the sealing assembly 23 includes a first seal 230 and a second seal 231. The first seal 230 and the second seal 231 form a sealed space (not shown in the figure). Hydraulic oil is stored in the sealed space. By extracting or replenishing hydraulic oil into the sealed space, the pressure of the hydraulic oil in the sealed space is controlled, thereby enabling the first roller 200 to abut against or disengage from the inner wall of the slide 3 at the recess 30.

[0039] In some implementation scenarios, both the first seal 230 and the second seal 231 are O-rings. Of course, in other implementation scenarios, the first seal 230 and the second seal 231 can also be rotary oil seals or other devices with sealing functions. This application does not impose specific restrictions here.

[0040] In one embodiment, the swing head auxiliary linear guide clamping structure 2 proposed in this application further includes an external hydraulic device and an oil pipe (not shown in the figure), wherein the external hydraulic device is used to extract and replenish hydraulic oil, one end of the oil pipe is connected to the external hydraulic device, and the other end is connected to the oil inlet 24.

[0041] Specifically, the external hydraulic device is used to draw and replenish hydraulic oil into the oil inlet 24, and the oil pipe is used to transmit hydraulic oil, thereby controlling the pressure of the hydraulic oil and ensuring that the first roller 200 can abut against or disengage from the inner wall of the slide 3 at the recess 30.

[0042] In one implementation, please refer to... Figure 2 and Figure 3 The ratio of the distance from the support point 2110 to the side surface of the swing head 4 near the slide 3 to the distance from the outer wall of the slide 3 away from the recess 30 to the side surface of the swing head 4 near the slide 3 is in the range of 1 / 4 to 1 / 2.

[0043] Specifically, the ratio of the distance from the support point 2110 to the side surface of the swing head 4 near the slide 3 to the distance from the outer wall of the slide 3 away from the recess 30 to the side surface of the swing head 4 near the slide 3 is in the range of 1 / 4 to 1 / 2, for example, the ratio is 3 / 10, 1 / 3 or 1 / 2, etc.

[0044] In one implementation scenario, the ratio of the distance from support point 2110 to the surface of the swing head 4 near the slide 3 to the distance from the outer wall of the slide 3 away from the recess 30 to the surface of the swing head 4 near the slide 3 is 1 / 2. In other implementation scenarios, the range of the ratio of the distance from support point 2110 to the surface of the swing head 4 near the slide 3 to the distance from the outer wall of the slide 3 away from the recess 30 to the surface of the swing head 4 near the slide 3 is related to the actual requirements, and this application does not impose specific limitations here.

[0045] Please continue reading. Figure 2 Zhihe Figure 5 This application also provides a machine tool processing equipment 1, including a slide 3, a swivel head 4, a slide rail assembly 5, and a swivel head auxiliary linear rail clamping structure 2 as described in any of the above embodiments, wherein the swivel head 4 is rotatably connected to the slide 3; the slide rail assembly 5 includes a linear rail 50 and a slider 51, the linear rail 50 is disposed on the surface of the slide 3 near the swivel head 4, the slider 51 is fixed on the swivel head 4 and slidably disposed on the linear rail 50, and the swivel head auxiliary linear rail clamping structure 2 is disposed on the swivel head 4.

[0046] Specifically, the oscillating head 4, connected to the slider 51, slides along the linear guide 50, enabling the oscillating head 4 to rotate left and right at an angle to process complex workpieces. At the same time, an auxiliary linear guide clamping structure 2 is added between the oscillating head 4 and the slide block 3 to reduce the load on the linear guide 50 and the slider 51, improve the life of the linear guide 50 and the slider 51, avoid frequent disassembly and assembly of the linear guide 50 and the slider 51 for maintenance, reduce maintenance costs, and improve processing efficiency and structural stability.

[0047] In one implementation scenario, the surface of the swing head 4 near the slide 3 is provided with a receiving part (not shown in the figure), and the swing head auxiliary rail clamping structure 2 is provided at the receiving part.

[0048] Specifically, the oscillating head auxiliary guide clamping structure 2 is located in the receiving part of the surface of the oscillating head 4 near the slide 3. It occupies little space, which makes the oscillating head 4 and slide 3 simple and compact in shape, and more adaptable to processing.

[0049] In one implementation scenario, there are two sliders 51, the linear guide 50 is curved, and the swing head auxiliary linear guide clamping structure 2 is located below the linear guide 50 and in the middle of the two sliders 51, and is relatively stationary with respect to the two sliders 51.

[0050] Specifically, the swing head auxiliary rail clamping structure 2 is located below the rail 50 and between the two sliders 51. When the swing head 4 rotates left and right, the swing head auxiliary rail clamping structure 2 and the two sliders 51 remain relatively stationary, thereby ensuring the stability of the overall structure and improving the machining accuracy.

[0051] In one specific implementation scenario, the linear guide 50 is semi-circular in shape, which can meet the large-angle rotation of the oscillating head 4 to process complex workpieces. Of course, in other implementation scenarios, the length and shape of the linear guide 50 can be set according to the actual application, and this application does not impose specific restrictions here.
