Description

Technical Field

[0001] This invention relates to the field of machinery, and more particularly to a lead screw module propulsion device with high stability. Background Technology

[0002] Currently, with the advancement of industrial mechanization, mechanical transmission devices are widely used in various types of equipment. However, many problems still exist, including complex design structures, inconvenient transmission, small transmission load capacity, high failure rate, difficult maintenance, inaccurate positioning, and high noise levels. These are all significant drawbacks of existing mechanical transmission devices. Slide table devices, due to their linear movement characteristics, are widely used on industrial machine tools. Linear movement is required to support the working mechanism, which is driven by a linear guide rail to move linearly, facilitating calibration and operation.

[0003] Our team's research has revealed that existing lead screw modules mainly use a sliding block as the movable element and a guide rail as the fixed element, or a single lead screw or single sliding block lead screw module structure. These structures are suitable for rapid conveying and movement, but when heavy equipment such as a grinding device needs to be moved, the poor stability and structural integrity often lead to large adjustment errors. Therefore, it is necessary to develop a lead screw module propulsion control device with higher stability. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the existing device by proposing a highly stable lead screw module propulsion device.

[0005] To overcome the shortcomings of the prior art, the present invention adopts the following technical solution:

[0006] A highly stable lead screw module propulsion device includes: a base;

[0007] The power module is used to provide power to the mobile platform for sliding.

[0008] The guide rail module is used to limit the sliding path of the mobile platform and assist the mobile platform in smooth sliding.

[0009] The sensing module is used to monitor whether the mobile platform has reached the monitoring position;

[0010] The mobile platform, mounted on the guide rail module, is used to mount the machining equipment and to move the machining equipment.

[0011] The power module includes a drive motor, a first bearing housing, a second bearing housing, a lead screw, and a connecting slider. The drive motor is fixedly mounted on the base. The first and second bearing housings are fixedly mounted on the base. The lead screw is rotatably mounted on the first and second bearing housings and is connected to the main shaft of the drive motor via a coupling. The connecting slider is slidably mounted on the lead screw and is connected to the moving platform. The connecting slider is configured to move along the lead screw through rotation of the lead screw, thereby moving the moving platform.

[0012] The guide rail module includes a bottom guide rail mechanism and a side guide rail mechanism. The bottom guide rail mechanism is located below the moving platform, and the side guide rail mechanism is located on the side of the moving platform.

[0013] The bottom guide rail mechanism includes a first slide rail and a first limiting block. The first limiting block is fixedly installed on the base. The first slide rail is connected to the mobile platform and is slidably disposed on the first limiting block.

[0014] Furthermore, the bottom guide rail mechanism is provided in two sets, both of which are located below the mobile platform.

[0015] Furthermore, the side guide rail mechanism includes a second slide rail and a second limiting block. The second limiting block is fixedly installed on the base, the second slider is connected to the moving platform, and the first slide rail is slidably disposed on the second limiting block.

[0016] Furthermore, the mobile platform is also provided with a locking block, which is located below the second slide rail and is used to provide support to the second slide rail.

[0017] Furthermore, the side of the mobile platform is provided with a side protrusion extending horizontally outward, and a locking plate is installed on the top of the base. The locking plate is installed above the side protrusion of the mobile platform and is used to lock the mobile platform.

[0018] Furthermore, the sensing module includes a generating mechanism and a monitoring mechanism. The generating mechanism is used to trigger the response of the monitoring mechanism, and the monitoring mechanism is used to monitor and record the response trigger value of the generating mechanism.

[0019] The generating mechanism includes a touch rod and an adjusting screw. The monitoring mechanism is configured as a pressure sensor. The touch rod is mounted on the connecting slider. The second fixed seat is provided with a screw hole. The adjusting screw is threadedly connected to the screw hole. The pressure sensor is fixedly mounted on the adjusting screw and faces the touch rod. It is configured such that the touch rod contacts the pressure sensor as the connecting slider moves. The adjusting screw is used to adjust the position of the pressure sensor.

[0020] The beneficial effects achieved by this invention are:

[0021] By setting an adjusting screw, the position of the pressure sensor can be adjusted, thereby controlling the working thread range;

[0022] The guide rail mechanism is set up with slide rails installed on the moving platform, and the limit block serves as a fixed limit structure, making the movement of the moving platform smoother and more gentle.

[0023] By setting up a guide rail module, which includes a bottom guide rail and side guide rails, the movement path of the mobile platform is restricted while it can withstand loads in multiple directions, thereby improving the stability of the mobile platform's operation.

[0024] By setting up a sensing module, the movement of the mobile platform can be controlled and monitored;

[0025] By setting up a mobile platform, the device can be adapted and installed as needed to achieve its propulsion function.

[0026] A spring is installed on the sensing module to smoothly and gradually apply the detection force to the sensing module, thereby extending the service life of the pressure sensor and improving the monitoring range. Attached Figure Description

[0061] The mobile platform 5 is also provided with a locking block 51, which is located below the second slide rail and is used to provide support to the second slide rail;

[0062] The side of the mobile platform 5 is also provided with a side protrusion 52 extending outward horizontally, and the top of the base 1 is also provided with a locking plate 11.

[0068] The touch rod 41 is also provided with a spring 44, and the spring 44 is positioned toward the pressure sensor 43;

[0069] When the power module 2 of this device is in operation, the drive motor 21 drives the lead screw 24 to rotate, thereby driving the connecting slider 25, which is threadedly connected to the lead screw 24, to move. The moving platform 5 set on the connecting slider 25 can only move back and forth due to the constraint of the guide rail module 3.

[0070] When the mobile platform 5 moves to the monitoring start position, the spring 44 on the touch rod 41 comes into contact with the pressure sensor 43, thereby triggering the monitoring of the pressure sensor 43. As the mobile platform 5 continues to approach the pressure sensor 43, the force applied to the spring 44 and the pressure sensor 43 gradually increases. Therefore, the monitoring can be achieved by reversing the travel position reached by the mobile platform 5 by monitoring the pressure.

[0071] When it is necessary to adjust the monitoring start position, simply rotate the adjusting screw 42 to adjust the distance between the pressure sensor 43 and the contact rod 41.

[0072] In practical applications, the grinding equipment is installed on the mobile platform 5 and then placed on one side of the product line.

[0073] This device allows for adjustment of the position of the pressure sensor 43 via an adjusting screw 42, thereby controlling the working range. The guide rail mechanism is configured as a slide rail mounted on the moving platform 5, with a limiting block serving as a fixed limiting structure, making the movement of the moving platform 5 smoother and more gradual. The guide rail module 3, equipped with a bottom guide rail and side guide rails, restricts the movement path of the moving platform 5 while bearing loads in multiple directions, thus improving the stability of the moving platform 5's operation. The sensing module 4 allows for the regulation and monitoring of the moving platform 5's travel distance. The moving platform 5 can be adapted to accommodate various mounting devices to achieve the device's propulsion function. A spring 44 is installed on the sensing module 4 to gently and smoothly apply the detection force, extending the lifespan of the pressure sensor 43 and improving the monitoring range.
