Description

Technical Field

[0001] This utility model belongs to the field of industrial automation technology, and in particular relates to a slide module that reduces lead screw wear. Background Technology

[0002] A slide module is a core component of automation that integrates high-precision linear motion, modular design, and high reliability. It is widely used in industrial robots, semiconductor manufacturing, new energy equipment, and other fields. For a lead screw slide module, its main structure includes a base that provides the mounting foundation, a lead screw as the driving element, a slider for mounting the load, a guide rail / guide rod for ensuring the linear motion of the slide, a support base and protective cover for ensuring the smooth sliding of the lead screw, and other components.

[0003] In a lead screw type slide module, the lead screw is the core structure that ensures accuracy, making its cost a relatively high proportion of the overall slide module. In daily use, for a slide module that moves in the vertical direction, the weight of the slider and the load it controls causes the threads on the lead screw to directly bear this weight. Since the wear and tear on the lead screw is mainly due to thread wear, the weight of the slider and the load will aggravate the wear of the threads, resulting in a reduced lead screw life. Replacing the lead screw is relatively expensive.

[0004] Therefore, a solution is needed that can reduce the wear of the lead screw and ensure that its wear cost is less than the cost of replacing the lead screw over its overall lifespan. Utility Model Content

[0005] The purpose of this invention is to provide a slide module that reduces lead screw wear, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a slide module for reducing lead screw wear, comprising a base, a lead screw, a support base, a guide unit, a slider, and a drive motor. The lead screw is supported by the support base and its rotation is controlled by the drive motor mounted on the base. The lead screw and the guide rail are arranged in the same direction. The slider is threadedly connected to the lead screw and slidably connected to the guide unit. A pulling assembly is also provided on the base, the pulling assembly comprising a synchronization unit and a transmission unit. The synchronization unit includes two synchronization pulleys and a synchronization belt that works in conjunction with the synchronization pulleys; the synchronization belt is fixed to the slider. The transmission unit includes a first bevel gear mounted on the drive motor shaft and a second bevel gear meshing with the first bevel gear. The second bevel gear and a synchronizing wheel in the synchronizing unit rotate synchronously on the same axis.

[0007] Preferably, the timing belt is provided with a first connector, the slide is provided with a second connector, and the first connector and the second connector are fixed by a connecting fastener.

[0008] Preferably, the synchronization unit is provided in two sets and is respectively located on both sides of the lead screw, and the two sets of synchronization units are respectively driven by a bevel gear.

[0009] Preferably, the pulling assembly further includes a tensioning pulley, and the timing belt passes between the tensioning pulley and the timing pulley.

[0010] Preferably, a plurality of stabilizing pulleys are provided between the synchronous belts to provide support for the synchronous belts.

[0011] Preferably, a gearbox is provided on the base, and the first bevel gear, the second bevel gear, and the tensioning wheel are all installed in the gearbox.

[0012] Preferably, the gearbox is fixed to the base, and the drive motor is fixed to the gearbox.

[0013] Preferably, the lead screw and the drive motor shaft are connected by a key or spline.

[0014] The beneficial effects of this utility model are as follows: In this solution, by fixing the slide table on the synchronous belt and making the synchronous pulley and the bevel gear two meshing with the bevel gear one rotate synchronously on the same axis, the weight of the slider and the load can be borne by the motor. The motor with the appropriate output power can be selected according to the actual use requirements. In terms of the service life of the motor and the lead screw, or the cost of the pulling component and the cost of the lead screw, the additional cost of this solution is far less than the cost of replacing the lead screw in advance. Among them, by setting tensioning pulleys and using appropriate specifications of tensioning pulleys according to usage requirements, it is ensured that the synchronous belt can effectively pull the slider to resist the gravity of the slider and the load on it. By setting up a stabilizing wheel for support, the stability of the synchronous belt can be effectively reduced, thus improving the stability of the synchronization unit. Attached Figure Description

Detailed Description of Embodiments

[0016] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, so as to define the protection scope of the present utility model more clearly.

[0017] Embodiment: Referring to Figures 1-3 , a sliding table module for reducing wear of a lead screw comprises a base 1, a lead screw 2, a support seat, a guide unit, a sliding block and a driving motor 4. The lead screw 2 is supported by the support seat and controlled to rotate by the driving motor 4 arranged on the base 1, the lead screw 2 and a guide rail are arranged in the same direction, the sliding block is threadedly connected to the lead screw 2 and slidably connected to the guide unit, a pulling assembly is further arranged on the base 1, and the pulling assembly comprises a synchronous unit and a transmission unit; The base 1 is an aluminum profile with a roughly U-shaped cross section, the lead screw 2 and the support seat are both arranged in the base 1, the guide unit comprises two guide rods 5 distributed on both sides of the lead screw 2, and the guide rods 5 are fixed in the base 1 through the fixing seat 6.

[0018] The synchronous unit comprises two synchronous pulleys 9 and a synchronous belt 10 used in cooperation with the synchronous pulleys 9, the synchronous belt 10 is fixed with the sliding block, and corresponding materials such as polyurethane, neoprene and the like are selected according to use requirements in actual use; The transmission unit comprises a first bevel gear 7 mounted on a rotating shaft of the driving motor 4 and a second bevel gear 8 meshed with the first bevel gear 7, the second bevel gear 8 and one synchronous pulley 9 in the synchronous unit rotate coaxially and synchronously, that is, the second bevel gear 8 and the synchronous pulley 9 can be fixed together. In production and design, after the transmission when the lead screw 2 rotates one circle (pitch), the rotation distance of the synchronous belt 10 driven by the bevel gear connected with the second bevel gear 8 should be calculated, and the movement distances of the two should be kept consistent.

[0019] wherein, referring to Figure 2 , Figure 3The pulling assembly also includes a tensioning wheel 11. The synchronous belt 10 passes between the tensioning wheel 11 and the synchronous wheel 9. The tensioning wheel 11 can be a wheel with a smooth surface, such as a bearing. Depending on the tension, different specifications of tensioning wheels 11 are selected for installation to ensure the tension of the synchronous belt 10.

[0020] Among them, a number of stabilizing wheels 12 are provided between the synchronous belts 10 to provide support for the synchronous belts 10. Specifically, the stabilizing wheels can be installed and fixed on the base 1 to ensure stable rotation. The structure of the stabilizing wheel 12 can be the same as that of the synchronous wheel 9, so that the stability can be better improved by meshing with the synchronous belt 10.

[0021] Among them, see Figure 3 , Figure 5 , Figure 6 The timing belt 10 is provided with a connector 13, and the slide table 3 is provided with a connector 14. The connector 13 and the connector 14 are fixed by a connecting fastener. The connector 13 can be a metal sheet covering the timing belt 10, which is fixed to the timing belt 10 by means of adhesive, binding or clamping. It should be noted that in order not to affect the collision problem when passing through the stabilizer 12, the thickness of the part covering the timing belt 10 should be controlled to avoid contact with the stabilizer 12.

[0022] The synchronization unit is provided in two sets, which are respectively located on both sides of the lead screw 2. The two sets of synchronization units are driven by a bevel gear 8. It should be noted that due to the transmission method of bevel gear 7 and bevel gear 8, the two bevel gears 8 on both sides of bevel gear 7 will rotate in opposite directions. Therefore, the timing belts 10 on both sides of the lead screw are fixed to the slider in different ways, but they should all be fixed on the part of the timing belt 10 that moves in the same direction.

[0023] Among them, see Figure 4 A gearbox 15 is provided on the base 1, and the first bevel gear 7, the second bevel gear 8 and the tensioning wheel 11 are all installed in the gearbox 15.

[0024] The gearbox 15 is fixed to the base 1, and the drive motor 4 is fixed to the gearbox 15. Specifically, the gearbox 15 includes a housing 151 and a cover 152. The design of the two should fit the part connected to the base 1 and the part connected to the motor to avoid dust ingress. A first connecting part 153 and a second connecting part 154 are fixed inside the housing 151. There is a distance between the first connecting part 153 and the second connecting part 154 that allows long bolts to enter, so that long bolts can enter and connect to the base 1 and the drive motor 4.

[0025] The lead screw 2 and the drive motor 4 shaft are connected by a key or spline. It is important to control the connection gap between them.

[0026] Working principle and process: This solution fixes the slide table 3 on the synchronous belt 10 and makes the synchronous pulley 9 and the bevel gear 8 meshing with the bevel gear 7 rotate synchronously on the same axis. This allows the weight of the slider and the load to be borne by the motor, thereby effectively improving the service life of the lead screw 2 and reducing the overall replacement cycle cost.

[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
