Description

Technical Field

[0001] This utility model relates to the field of linear module technology, specifically to a novel flat integrated oil injection screw slide. Background Technology

[0002] A widely used linear module is a drive unit that drives a slide block and a slider to perform reciprocating linear motion on a guide rail.

[0003] However, the aforementioned linear modules face maintenance difficulties after a period of use. Maintenance requires disassembling the module cover and lubricating the internal sliders and nuts, making maintenance complex. In addition to the inconvenience of maintenance, the conventional linear module has a relatively large distance from the center of the ball screw to the bottom mounting surface of the base, which affects the module's operational stability. Summary of the Invention

[0004] This utility model relates to a novel flat integrated oil injection screw slide, which can improve the above-mentioned problems of inconvenient maintenance and module movement stability.

[0005] The flat, integrated oil-filling screw slide of this utility model is characterized by comprising a drive unit, a body unit, and a sliding unit. The drive unit includes a motor, a motor plate, a fixed base, a tail support base, a coupling, and a ball screw. The body unit includes a base and a guide rail installed inside the base. The sliding unit includes an external oil-filling slide, a nut, an oil guide block, and a slider assembly installed on the lower end face of the external oil-filling slide. Oil-filling connectors are installed on both sides of the external oil-filling slide, and each connector is connected to an oil-filling channel. A slider assembly is installed on the lower end face of the external oil-filling slide, and each slider has an oil-filling hole on its upper surface. The oil-filling channel of the external oil-filling slide is connected to the oil-filling hole. An oil guide block is installed on the external oil-filling slide, connecting the oil-filling channels on both sides of the slide. A screw oil-filling channel is opened inside the oil guide block, allowing grease to flow to the ball screw along this channel. The distance from the center of the ball screw to the bottom mounting surface of the base is less than the distance from the upper surface of the slider to the bottom mounting surface of the base. The ratio of the distance from the upper surface of the external oil injection slide to the bottom mounting surface of the base to the distance from the center of the ball screw to the bottom mounting surface of the base is less than 2, resulting in a flatter screw slide. This invention, through the oil injection channel design of the sliding unit, makes the maintenance of the screw slide more convenient, and the flattened design makes the movement of the screw slide more stable.

[0006] The external oil injection slide of this utility model has oil injection ports on both sides, and each oil injection port is equipped with an oil injection connector. The oil injection connector is connected to the oil injection channel. When grease is injected into the oil injection connector, the grease can flow into the oil injection channel through the oil injection connector.

[0007] The oil injection channel of this utility model includes an oil injection port, an oil injection main channel, an oil injection channel one, an oil injection channel two, and an oil injection channel three; one end of the oil injection channel one is connected to the oil injection main channel, and the other end extends outward in the width direction of the external oil injection slide; one end of the oil injection channel two is connected to the oil injection main channel, and the other end extends along the installation direction of the nut on the external oil injection slide; one end of the oil injection channel three is connected to the oil injection main channel, and the other end extends in the opposite direction to the installation direction of the nut on the external oil injection slide.

[0008] As an optimized design, each slider in the slider assembly has an oil injection hole on its upper surface. An oil injection groove is machined at the position opposite to the oil injection hole of the slider on the external oil injection seat. After the rubber ring is installed in the oil injection groove, the slider is locked to the lower end face of the external oil injection seat. After the grease is injected from the oil injection joint, it flows through the main oil injection channel, oil injection channel one, and oil injection channel two, and then flows into the slider oil injection hole near the nut side. After flowing through the main oil injection channel, oil injection channel one, and oil injection channel three, it flows into the slider oil injection hole away from the nut side, so that the slider assembly is lubricated.

[0009] As an optimized design, an oil guide block is installed on the external oil injection slide. An oil guide connecting channel is opened inside the oil guide block, which connects the oil injection channel. When oil is injected into the oil injection ports on both sides of the external oil injection slide, the grease can flow from one side of the oil injection port to the other side of the oil injection port along the oil injection channel. In addition, a screw oil injection channel is opened inside the oil guide block, and the grease can flow along this channel to the ball screw for lubrication.

[0010] As an optimized design, the distance from the center of the ball screw to the bottom mounting surface of the base is less than the distance from the upper surface of the slider to the bottom mounting surface of the base, and the ratio of the distance from the upper surface of the external oil injection slide to the bottom mounting surface of the base to the distance from the center of the ball screw to the bottom mounting surface of the base is less than 2, making the screw slide more flat.

[0011] As an optimized design, the flat integrated oil injection screw slide also includes a motor, which is mounted on a motor plate. One end of the ball screw is fixed on a fixed base, and the other end is supported by the tail end support. The motor and the ball screw are connected by a coupling. After the motor is started, the ball screw will rotate under the drive of the motor, thereby driving the sliding unit to move on the main body unit.

[0012] The beneficial effects of this utility model are as follows: This utility model adds an oil injection channel inside the slide block and uses an oil guide block to connect the oil injection channel. There is no need to disassemble the slide cover plate. Grease can be injected from any external oil injection port of the oil injection slide block. The grease can flow along the oil injection channel to the ball screw and any slider of the slider assembly to lubricate them, making the maintenance of the screw slide block more convenient. The distance from the center of the ball screw of the screw slide block to the bottom mounting surface of the base is reduced, and the height of the screw slide block assembly is reduced, which improves the motion stability of the load on the slide block mounting surface and improves the motion accuracy of the module.

[0026] The structure and features of this utility model will be described below, and component numbers will be used for explanation throughout the description.

[0027] like Figure 1, Figure 2 As shown, the flat integrated oil injection screw slide of this utility model includes a main body unit 1, a sliding unit 2 and a drive unit 3.

[0028] The main body unit 1 extends along its length and includes a base 11 and two guide rails 12 locked onto the guide rail mounting surfaces inside the base 11. The guide rails 12 are laid along the length of the base 11 and are parallel to the extension direction of the base 11.

[0029] like Figure 3 As shown, the sliding unit 2 includes an external oiling slide 21, an oil guide block 23 mounted on the upper part of the external oiling slide 21, a nut 22 mounted on the end face of the external oiling slide 21, and a slider assembly 24 mounted on the lower end face of the external oiling slide 21. Figure 4 As shown, the external oil injection slide 21 has an oil injection port 243 on each of its two sides, and each oil injection port 243 is equipped with an oil injection connector 6. Figure 5 As shown, the lower end face of the external oiling slide 21 locks the slider assembly 24. Each slider 241 in the slider assembly 24 has an oiling hole 242 on its upper surface. The external oiling slide 21 has an oiling groove 25 machined at the position opposite to the oiling hole 242. The second oiling channel 213 and the third oiling channel 214 communicate with the oiling groove 25. After installing the rubber ring 5 in the oiling groove 25, the slider 241 is locked. On the lower end face of the external oil-filling slide block 21, after grease is injected from the oil-filling connector 6, it flows through the main oil-filling channel 211, the first oil-filling channel 212, the second oil-filling channel 213 and the oil-filling groove 25, and then flows into the slider oil-filling hole 242 on the side of the nut mounting end face 26. After flowing through the main oil-filling channel 211, the first oil-filling channel 212, the third oil-filling channel 214 and the oil-filling groove 25, it flows into the slider oil-filling hole 242 on the side away from the nut mounting end face 26, so that the slider assembly 24 is lubricated.

[0030] like Figure 6As shown, an oil injection channel is formed within the external oil injection slide 21, comprising a main oil injection channel 211, an oil injection channel one 212, an oil injection channel two 213, and an oil injection channel three 214. The main oil injection channel 211 intersects with the oil injection channels two 213 and three 214. After grease is injected from the oil injection connector 6, it flows into the main oil injection channel 211 and then flows to the oil injection channels two 213 and three 214 at the intersection. The oil injection channel two 213 extends along the length of the external oil injection slide 21, parallel to the extension direction of the base 11, and extends towards the nut mounting end face 26. The oil injection channel three 214 extends along the length of the external oil injection slide 21, parallel to the extension direction of the base 11, and extends in the opposite direction to the nut mounting end face 26. The oil injection channels two 213 and three 214 ensure that the entire oil injection channel flows along the length of the external oil injection slide 21. The second oil injection channel 213 and the third oil injection channel 214 end at both ends of the external oil injection slide 21. A base 7 is installed on the end face of the external oil injection slide 21 to terminate the second oil injection channel 213 and the third oil injection channel 214.

[0031] like Figure 7 , 8 As shown, the oil guide block 23 is locked to the upper part of the external oil injection slide 21, and the oil guide block 23 also has an oil injection channel inside, namely the screw oil injection channel 231 and the oil guide connecting channel 232. The oil guide connecting channel 232 connects the first oil injection channel 212, and grease can flow from any oil injection joint 6 into the main oil injection channel 211, the first oil injection channel 212, and reach the other oil injection joint 6, so that the entire oil injection channel flows along the width of the external oil injection slide 21. The screw oil injection channel 231 can lubricate the ball screw 36 with grease. Grease is injected from the oil injection joint 6, flows through the main oil injection channel 211, the first oil injection channel 212, and the screw oil injection channel 231, and then flows to the ball screw 36 to lubricate it. The oil injection channel 231 can lubricate the ball screw 36 and the nut 22 (which reciprocates on the ball screw 36) without the need to install an oil guide pipe on the nut 22 and the external oil injection slide 21.

[0032] like Figure 7 As shown, the ball screw 36 passes through the nut 22. The distance from the center of the ball screw 36 to the bottom mounting surface of the base 11 is distance 8. The distance from the upper surface of the slider 241 to the bottom mounting surface of the base 11 is distance 9. Distance 8 is less than distance 9. The distance from the upper surface of the external oil injection slide 21 to the bottom mounting surface of the base 11 is distance 10. The ratio of distance 10 to distance 8 is less than 2, which makes the height of the screw slide assembly smaller and requires less installation space. After the load is installed on the upper surface of the external oil injection slide 21, the linear motion stability is improved and the motion accuracy of the screw slide is higher.

[0033] The drive unit 3 includes a motor 31, a fixed base 33, a motor plate 32, a tail end support 34, a coupling 35, and a ball screw 36. The motor 31 is fixed to the motor plate 32. One end of the ball screw 36 is fixed to the fixed base 33, and the other end is supported by the tail end support 34. The ball screw 36 is connected to the motor 31 through the coupling 35. After the motor 31 is started, the ball screw 36 will rotate under the drive of the motor 31, thereby driving the sliding unit 2 to move on the main body unit 1.

[0034] The above describes the embodiments of this utility model. This utility model not only improves the accuracy and maintenance convenience of the linear module, but also allows grease to be injected into the external oil injection slide 21 oil injection connector 6 without disassembling the screw slide cover plate 4. The grease can flow into the ball screw 36 and the slider assembly 24, thus achieving the purpose of this utility model.

[0035] The above description is one of the implementable examples of this utility model and cannot completely limit the scope of implementation of this utility model. In other words, any transformation of the expression and language based on this utility model shall be within the scope of implementation of this utility model.
