Description

Technical Field

[0001] The utility model relates to the technical field of linear modules, in particular to a flat self-lubricating embedded module. Background Art

[0002] A widely used embedded module includes an embedded rail base, an embedded rail slider, and a ball screw that passes through the through-hole of the slider and can drive the slider to perform reciprocating linear motion on the base.

[0003] However, the distance between the center of the through-hole of the slider of the above-mentioned embedded module and the center of the ball track of the slider is relatively large. When a load is installed on the upper surface of the slider and performs linear motion driven by a motor, the load is prone to shaking, the stability of the load is poor, and it has an adverse effect on the accuracy of the module. Moreover, the base of the above-mentioned embedded module is not integrally formed, and the base and the side baffle need to be assembled separately. The side baffle is fixed to the front and rear end supports of the module by screws, and the installation steps are complex. Summary of the Invention

[0004] The utility model relates to a flat self-lubricating embedded module, which can solve the above problems.

[0006] The rigid rails are embedded in the base grooves on the left and right side walls of the base of the utility model and extend along the length direction of the base. The slider is similar to the base, and the rigid rails extending along the length direction of the slider are embedded in the slider grooves on both left and right side walls of the slider. The rigid rails in the base grooves cooperate with the rigid rails in the slider grooves to complete the component support and motion guidance work.

[0007] The nut described in the present utility model is fixed in the nut mounting hole penetrated by the sliding seat through a fixing pin. Steering gear components are installed on both end faces of the sliding seat. The cooperation between the steering gear components and the nut mounting hole of the sliding seat forms an installation space for the ball screw. After the ball screw penetrates the nut, the ball screw is fixed at both ends of the body unit.

[0008] As an optimized design, the base is integrally formed. The top of the base has top brackets symmetrically arranged in the left-right direction and extends towards the center of the base. The left and right sides of the base extend upward to be connected with the top brackets.

Both ends of the steel belt are respectively fixed on the first support piece and the second support piece, forming a fully sealed dust-proof effect for the whole product.

[0010] As an optimized design, the flat self-lubricating inlaid module further includes a motor. The motor is installed on a motor seat and is connected to the ball screw through 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 in the sliding groove.

[0011] As an optimized design, both sides of the self-lubricating sliding seat body have oil injection ports, and the oil injection ports are connected to the internal oil injection path of the self-lubricating sliding seat. The oil injection path includes a first oil injection path and a second oil injection path.

[0024] The structure and features of the present utility model will be described below, and component numbers will be used for explanation throughout the description process.

[0025] As Figure 1 、 Figure 2 shown, the flat self-lubricating embedded module of the present utility model includes a body unit 1, a sliding unit 2 and a drive unit 3.

[0026] The body unit 1 extends in the length direction. The body unit 1 includes a base 11, two base grooves 15 provided on the left and right side walls of the base 11, two rigid rails 14, a first support member 12, and a second support member 13. The two rigid rails 14 embedded in the base grooves 15 extend in the length direction and are as long as the base 11. The side walls 20 of the base extend upward and are connected to the top bracket 19. The entire base 11 is integrally formed. The top bracket 19 and the bottom 16 of the base form a sliding groove 17. The first support member 12 and the second support member 13 are respectively fixed to the two end faces 18 of the base and abut against the two ends of the top bracket 19. The first support member 12, the second support member 13, the bottom 16 of the base, the side walls 20 of the base, and the top bracket 19 together form a closed structure. A steel belt 4 is provided on the top bracket 19, and the two ends of the steel belt 4 are fixed to the first support member 12 and the second support member 13, so that the whole product forms a fully sealed dust-proof effect.

[0027] The sliding unit 2 includes a self-lubricating slide 21, two rigid rails 24 embedded on both sides of the self-lubricating slide 21, two steering gear assemblies 23 installed on the two end faces of the self-lubricating slide 21, and a nut 25.

[0028] As Figure 3 shown, the distance from the center 29 of the nut mounting hole of the self-lubricating slide 21 to the upper surface 28 of the self-lubricating slide is distance one 5. The distance from the center 29 of the nut mounting hole of the self-lubricating slide 21 to the center of the ball track 27 of the self-lubricating slide 21 is distance two 6. The distance from the center 29 of the nut mounting hole of the self-lubricating slide 21 to the bottom of the self-lubricating slide is distance three 7. The ratio of distance one 5 to distance two 6 is less than 2, and the ratio of distance one 5 to distance three 7 is approximately equal to 1. Reducing the height of the center 29 of the nut mounting hole of the self-lubricating slide makes the combined height of the embedded module smaller, the installation space required for the module smaller, the linear motion stability after the load is mounted on the upper surface 28 of the self-lubricating slide is improved, and the motion accuracy of the module is higher.

[0029] As Figure 4 shown, both sides of the self-lubricating slide 21 are provided with oil injection ports 22. The oil injection ports 22 are communicated with the internal oil injection path of the self-lubricating slide 21. The oil injection path includes a first oil injection path 8 and a second oil injection path 9. After the grease is injected from the oil injection ports 22, the grease flows into the ball screw 34 and the steering gear assembly 23 along the first oil injection path 8 and the second oil injection path 9 respectively. The nut 25 is installed in the nut mounting hole 26 penetrating through the slide and is fixed to the slide by a pin.

[0030] As Figure 5 shown, the side walls 20 of the base are connected to the top bracket 19. The integrally formed structure eliminates the processing requirements for the side baffles of the traditional embedded module, simplifies the module assembly steps, and is more conducive to mass production.

[0031] As Figure 6 shown, the drive unit 3 includes a motor 31, a motor base 32, a coupling 33 and a ball screw 34. The motor 31 is fixed to the motor base 32 and connected to the ball screw 34 through the coupling 33. After starting the motor 31, the ball screw 34 will rotate driven by the motor 31, thereby driving the sliding unit 2 to move in the sliding groove 17.

[0032] The above is the implementation manner of the present utility model. The present utility model not only improves the module accuracy and the convenience of module assembly, but also reduces the installation space required by the module. Without disassembling the module accessories, grease is injected into the oil injection port 22 of the self-lubricating slide base 21, and the grease can flow into the ball screw 34 and the steering gear assembly 23, making the module maintenance more convenient and achieving the purpose of the present utility model.

[0033] The above content is one of the implementable cases of the present utility model and cannot completely define the implementation scope of the present utility model. In other words, all expressions transformed and linguistically packaged according to the present utility model fall within the implementation scope of the present utility model.
