[0002] Linear guides are used to support and guide moving parts to perform reciprocating linear motion in a given direction. Linear guides are used in linear reciprocating motion situations. They have a higher rated load than linear bearings and can withstand a certain torque. They can achieve high-precision linear motion under high load conditions.

[0003] High-precision linear guides are a crucial component in machine tools and other high-precision instruments, enabling precise reciprocating motion at a constant speed. Linear guides primarily consist of sliders and rails. Sliders, as key components of guide rails, are primarily used for friction sliding.

[0043] See also Figures 1-9 The present invention provides a special machine tool for slotting a workpiece 700. The special machine tool includes: a frame 100; a forging assembly 200, which is arranged on the frame 100 and includes: a main shaft 211 and a forging 220, and the main shaft 211 rotates to drive the forging 220 to move axially on the main shaft 211; a moving assembly 300, which is arranged on the frame 100 and includes a guide rail 310 and a moving block 320, and the moving block 320 is arranged on the guide rail 310, and the moving block 320 is provided with There is a workpiece 700; a driving assembly, the driving assembly is arranged on the frame 100, and the driving assembly includes a first driving assembly 410 and a second driving assembly 420, the first driving assembly 410 is used to drive the main shaft 211 to rotate, and the second driving assembly 420 is used to drive the moving block 320 to move on the guide rail 310; wherein, the first driving assembly 410 drives the main shaft 211 to rotate, and pushes the forging 220 to move toward the moving block 320 through the main shaft 211; the second driving assembly 420 drives the moving block 320 to move toward the forging 220.

[0044] Specifically, the forging assembly 200, the moving assembly 300, and the drive assembly are all mounted on the frame 100. The forging assembly 200 includes a spindle 211 and a forging 220, with the spindle 211 and the forging 220 being linked by a rolling retainer 250 and a rolling member 260. The moving assembly 300 includes a guide rail 310 and a moving block 320. The guide rail 310 is fixed to the frame 100, and the moving block 320 is movable on the guide rail 310. The drive assembly includes a first drive assembly 410 and a second drive assembly 420, which are respectively mounted at opposite ends of the frame 100.

[0045] Before the slotting work, the first drive assembly 410 and the second drive assembly 420 are respectively arranged at the two ends of the frame 100, the moving block 320 and the forging assembly 200 are both arranged between the first drive assembly 410 and the second drive assembly 420, the workpiece 700 is arranged on the moving block 320, the moving block 320 is arranged on the guide rail 310, and the forging part 220 is in a position away from the moving block 320.

[0046] During the grooving process, when the second drive assembly 420 starts working, a gear box is designed inside the second drive assembly 420 to adjust the movement speed of the moving block 320 and drive the moving block 320 to move on the guide rail 310. The moving block 320 can drive the workpiece 700 to move along the guide rail 310 from the side of the first drive assembly 410 to the side of the second drive assembly 420. When the first drive component 410 starts working, the first drive component 410 drives the main shaft 211 to rotate. The first drive component 410 is used to output power to the main shaft 211 and can adjust the speed of the main shaft 211. The main shaft 211 is connected to the rolling retainer 250, and the rolling retainer 250 is driven to rotate by the rotation of the main shaft 211. The rolling member 260 is fixed to the edge of the rolling retainer 250, and at least a part of the rolling member 260 is embedded in the rolling retainer 250. The rolling member 260 rotates radially along the main shaft 211 as the rolling retainer 250 rotates. When the rolling member 260 contacts the forging 220, the forging 220 is pressed by the rolling body, and the forging 220 is moved axially along the main shaft 211 from the second drive component 420 side to the first drive component 410 side.

[0047] After a certain moment, the workpiece 700 and the forging 220 come into contact. The second drive assembly 420 continues to drive the moving block 320 toward the forging 220, while the first drive assembly 410 continues to drive the forging 220 toward the workpiece 700. When all parts of the workpiece 700 are in complete contact with the casting, the slotting of the workpiece 700 is complete. The second drive assembly 420 continues to drive the moving block 320 toward the side closest to the second drive assembly 420, lowering the workpiece 700 at a predetermined position. After the work is completed, the moving block 320 and the forging 220 return to their initial positions. Driven by the second drive assembly 420 and the first drive assembly 410, respectively, the workpiece 700 and the forging 220 move relative to each other, improving the efficiency of the forging process.

[0048] For further information, see Figure 2-Figure 3 The forging assembly 200 also includes: a spindle bearing seat 210, which is arranged on the frame 100, and a spindle 211 is provided on the spindle bearing seat 210; a forging bracket 230, which is provided with a forging 220, and at least a portion of the forging 220 is embedded in the forging bracket 230; wherein, the forging bracket 230 is arranged between the first driving assembly 410 and the second driving assembly 420, and a first accommodating space 231 is formed between the forging bracket 230 and the forging 220.

[0049] For example, the spindle 211 bearing is fixed to the frame 100. The spindle 211 bearing is used to support the spindle 211, ensuring that the spindle 211 is in a horizontal plane and increasing the stability of the spindle 211. The forging bracket 230 is provided with a forging 220, and at least a portion of the forging 220 is embedded in the forging bracket 230. The forging bracket 230 is used to support the forging 220. At least a portion of the forging 220 is embedded in the forging bracket 230 to improve the stability of the forging 220 during movement and ensure that the forging 220 moves in a horizontal plane. The forging bracket 230 is disposed between the first drive assembly 410 and the second drive assembly 420, allowing the forging 220 to move between the first drive assembly 410 and the second drive assembly 420. A first accommodating space 231 is formed between the forging bracket 230 and the forging 220 for accommodating the rolling retainer 250 and the rolling member 260.

[0050] Preferably, the main shaft 211 has two bearings, and both ends of the main shaft 211 are respectively provided on the two main shaft 211 bearings. The two main shaft 211 bearings are provided to improve the stability of supporting the main shaft 211.

[0051] For further information, see Figure 3The forging assembly 200 also includes: a rolling retainer 250, which is connected to the main shaft 211; at least one rolling member 260, which is arranged on the forging bracket 230; wherein, at least one rolling member 260 is arranged on the edge of the rolling retainer 250, and at least a portion of the at least one rolling member 260 is embedded in the rolling retainer 250.

[0052] For example, the forging assembly 200 includes a rolling retainer 250 and at least one rolling element 260. The rolling retainer 250 is disposed within the first accommodating space 231 and is fixedly connected to the spindle 211. The rotation of the spindle 211 drives the rotation of the rolling retainer 250. At least one rolling element 260 is disposed at the edge of the rolling retainer 250, with at least a portion of the rolling element 260 embedded in the rolling retainer 250 to provide a tighter fixation between the rolling element 260 and the rolling retainer 250. As the rolling element 260 contacts the forging 220, it pushes the forging 220 to move axially along the spindle 211. The forging assembly 200 also includes a stopper 280, which is fixed to the forging support 230 and radially disposed around the spindle 211. The spindle 211 passes through the stopper 280. The stopper 280 further limits the position of the rolling element 260 to prevent it from flying out when the spindle 211 rotates too fast.

[0053] Preferably, the number of rolling members 260 can be 6. Providing multiple rolling members 260 can further improve the moving rate of the forging 220. Within a certain range, the moving rate of the forging 220 will increase with the increase in the number of rolling members 260, and the rolling members 260 are evenly distributed on the edge of the rolling retaining member 250. The uniform distribution of the rolling members 260 can make the movement of the forging 220 more uniform and stable.

[0054] For further information, see Figure 4 The forging part 220 includes: at least one moving part 221, at least a portion of the at least one moving part 221 is embedded in the forging bracket 230; at least one forging head 240, at least one forging head 240 extends from the side of the moving part 221 away from the main shaft 211; wherein, a protrusion 222 is provided on the side of the moving part 221 close to the main shaft 211, and when the protrusion 222 contacts the rolling part 260, the forging part 220 moves axially along the forging bracket 230.

[0055] For example, the forging part 220 also includes at least one moving part 221 and at least one forging head 240. The forging head 240 is fixed on the side of the moving part 221 away from the main shaft 211. The forging head 240 is used to contact the workpiece 700 to groove the workpiece 700. At least a portion of the moving part 221 is embedded in the forging bracket 230 to make the moving part 221 more stable when moving; a protrusion 222 is provided on the side of the moving part 221 close to the main shaft 211. The protrusion 222 is provided to increase the probability of contact between the moving part 221 and the rolling part 260, thereby further improving the efficiency of the movement of the forging part 220.

[0056] Preferably, the protrusion 222 is in the shape of an arc that is thick in the middle and thin at both sides, which can reduce the force acting when the moving member 221 and the rolling member 260 contact each other and reduce the wear between the two.

[0057] Furthermore, the forging head 240 includes: a first forging head 241, the cross-sections of the first forging head 241 on both sides are the same size; a second forging head 242, the cross-section of the second forging head 242 gradually decreases in the direction away from the first forging head 241; a third forging head 243, the cross-section of the third forging head 243 gradually decreases in the direction away from the second forging head 242; wherein, the second forging head 242 connects the first forging head 241 and the third forging head 243.

[0058] Specifically, the forging head 240 consists of three parts: a first forging head 241, a second forging head 242, and a third forging head 243. The first forging head 241 is a long shaft component with a uniform trapezoidal cross-section and the same cross-section at both ends. Initially, the first forging head 241 is located away from the moving block 320; one side of the second forging head 242 is connected to the first forging head 241, and the other side of the second forging head 242 is connected to the third forging head 243. The cross-section of the second forging head 242 gradually decreases in the direction away from the first forging head 241 and closer to the main shaft 211. The second forging head 242 is a long shaft component with a trapezoidal cross-section that uniformly decreases in the direction away from the first forging head 241 and closer to the main shaft 211. The third forging head 243 is also a long shaft component with a trapezoidal cross-section that uniformly decreases in the direction away from the first forging head 241 and closer to the main shaft 211. During the forging process, the first forging head 241 gradually approaches the workpiece 700 until the forging is completed. Under the condition of a constant force, the smaller the force area, the greater the pressure. The cross-section of the third forging head 243 close to the workpiece 700 is the smallest, and a greater pressure can be obtained when in contact with the workpiece 700, making it easier to groove the workpiece 700. The cross-sections of the third forging head 243 and the second forging head 242 gradually increase in the direction close to the first forging head 241, and are streamlined. The streamlined setting can give the forging process a transition period, better reduce resistance, thereby further reducing noise, and is beneficial to improving the forging quality. The first forging head 241 is a long axis component with a uniform trapezoidal cross-section, which can further improve the forging quality and improve processing accuracy.

[0059] For further information, see Figure 5 The workpiece 700 includes a first connecting member 710 and two second connecting members 720, and the two second connecting members 720 are connected to one side of the first connecting member 710, and the forging head 240 is used to process the inner side of the two second connecting members 720; at least one forging head 240 is two, and the two forging heads 240 are respectively arranged on both sides of the moving member 221, and the two forging heads 240 are symmetrically arranged.

[0060] For example, the two second connecting parts 720 are fixed on one side of the first connecting part 710, and the forging head 240 is used to process the inner side of the two second connecting parts 720; at least one forging head 240 is two, and when there are two forging heads 240, the two forging heads 240 are respectively arranged on both sides of the moving part 221 away from the main shaft 211, and the forging heads 240 extend laterally from the surface of the moving part 221, and the two forging heads 240 are symmetrically arranged.
