Description

Technical Field

[0001] The utility model relates to the technical field of sliding drive devices, in particular to a composite sliding drive device and a silicon rod grabbing manipulator. Background Art

[0002] In the prior art, for the sliding drive device of the silicon rod clamp, in order to ensure the load-bearing capacity of the sliding drive device, the plane of the slide is mostly slidably connected to the base in the form of plane contact. This single form of connection pair causes the sliding drive device to increase the friction between the slide and the base due to wear of the slide and the base after a period of use. While adjusting the vertical friction between the slide and the base, it is also necessary to use the inlay strip to adjust the horizontal friction between the slide and the base. This undoubtedly increases the difficulty of maintaining the sliding device, and is not conducive to improving the operating accuracy and stability of the sliding drive device. Utility Model Content

[0005] (2) Technical solution

[0006] In order to achieve the above-mentioned purpose, the main technical solutions adopted by this utility model include:

[0007] In the first aspect, the utility model provides a composite sliding drive device, including a slide, a base, a linear guide and a pressure plate, the slide is connected to the base by the linear guide along a first direction; the lower part of the slide forms a first contact surface extending along the first direction, the upper part of the pressure plate forms a second contact surface, and the pressure plate is connected to the base so that the first contact surface and the second contact surface slide and abut along the first direction.

[0008] In one technical solution of the present invention, two spaced-apart connecting parts extend from the base, forming an installation area between the two connecting parts, and two pressure plates are provided and are detachably connected to the two connecting parts one by one; the linear guide rail and the slide are both located in the installation area.

[0009] In one technical solution of the present invention, a pad is further included, which is connected between the pressing plate and the connecting portion to form a vertical spacing adjustment member between the first contact surface and the second contact surface.

[0010] In a technical solution of the present invention, the pad is provided with various thickness models; or, the pad is an elastic plate.

[0011] In a technical solution of the present invention, a threaded hole is provided on the connecting portion, and the backing plate and the pressure plate are detachably connected to the connecting portion by bolts.

[0015] (3) Beneficial effects

[0016] The beneficial effects of the present invention are as follows: in the composite sliding drive device of the present invention, the second contact surface on the upper portion of the pressure plate slides and abuts against the first contact surface on the lower portion of the slide in a first direction, and in conjunction with the linear guide, can further restrict the sliding direction of the slide.

This helps to improve the service life of the sliding device and ensures the sliding accuracy of the slide in the sliding device.

[0017] At the same time, when maintaining the drive device, it is only necessary to pay attention to the longitudinal mineral volume of the first contact surface and the second contact surface, which greatly reduces the maintenance complexity and difficulty of the drive device.

[0030] In order to better explain the present invention, and to facilitate understanding, the following Figure 1-Figure 2 , through the specific implementation method, the utility model is described in detail. Among them, the directional nouns such as "upper" and "lower" mentioned in this article are Figure 1 The orientation is referenced.

[0031] Example 1:

[0032] Reference Figure 1-Figure 2 An embodiment of the utility model provides a composite sliding drive device, including a slide 1, a base 2, a linear guide 3 and a pressure plate 4. The slide 1 is connected to the base 2 by sliding along a first direction through the linear guide 3; the lower part of the slide 1 forms a first contact surface 100 extending along the first direction, and the upper part of the pressure plate 4 forms a second contact surface 400. The pressure plate 4 is detachably connected to the base 2, and the first contact surface 100 and the second contact surface 400 slide and abut along the first direction.

[0033] In this embodiment, the slide 1 is slidably connected to the base 2 through a linear guide rail 3. The linear guide rail 3 is used to guide the slide 1 to slide on the base 2 along a first direction to ensure the accuracy and stability of the sliding, that is, the first guide rail guides the sliding direction of the slide 1.

[0034] The second contact surface 400 on the upper portion of the pressure plate 4 slides and abuts against the first contact surface 100 on the lower portion of the slide 1 in a first direction, and in conjunction with the linear guide 3, further restricts the sliding direction of the slide 1. Because the linear guide 3 acts as a component restricting the sliding direction, it is not capable of carrying large loads. However, large loads can be carried through the sliding abutment between the first contact surface 100 and the second contact surface 400. This helps to improve the service life of the sliding device and also ensures the sliding accuracy of the slide 1 in the sliding device.

[0035] At the same time, when maintaining the drive device, it is sufficient to pay attention to the longitudinal volume of the first contact surface 100 and the second contact surface 400, which greatly reduces the maintenance complexity and difficulty of the drive device. Fewer maintenance operations are also conducive to ensuring the operation consistency of the drive device before and after maintenance, and ensuring the operation stability and operation accuracy of the drive device.

[0036] Specifically, the slide 1 is slidably connected to the base 2 through a linear guide 3. When an external driving force acts on the slide 1, the slide 1 can slide along the linear guide 3 in a first direction. The lower first contact surface 100 of the slide 1 and the upper second contact surface 400 of the pressure plate 4 slide and abut along the first direction. This design can ensure the stability and accuracy of the slide 1 during the sliding process, and can also change the sliding resistance and stability of the slide 1 by adjusting the tightness of the pressure plate 4. The detachable connection design between the pressure plate 4 and the base 2 allows the user to easily replace the pressure plate 4 of different sizes or adjust the position of the pressure plate 4 to adapt to different work needs and working environments.

[0037] Grease is provided between the first contact surface 100 and the second contact surface 400 to reduce wear between the two and improve the running smoothness of the slide 1 .

[0038] Guided by linear guides 3, slide 1 achieves high-precision sliding, meeting the demands of precision machining and positioning. The sliding abutment between pressure plate 4 and slide 1 ensures stability during sliding, reduces vibration and sway, and meets the requirements of carrying heavy loads. The detachable connection between pressure plate 4 and base 2 allows users to easily adjust the position of pressure plate 4 or replace it with a different size to suit different work requirements.

[0039] The slide 1 further includes a ball screw 6, a screw nut 7, and a drive motor 8. The ball screw 6 extends in a first direction and is rotatably connected to the base 2. The screw nut 7 cooperates with the ball screw 6, and the drive motor 8 is driven and connected to the ball screw 6. The slide 1 is fixedly connected to the screw nut 7. In this way, under the coordinated action of the screw nut 7 and the ball screw 6, combined with the guiding and bearing functions of the linear guide 3 and the pressure plate 4, the slide 1 can operate more stably and reliably, which is conducive to further improving the operating accuracy and stability of the slide 1. When the drive motor 8 is configured as a servo motor, the slide 1 can realize forward and reverse operation, ensuring the flexibility of the use of the sliding device.

[0040] The linear guide rail 3, the connecting portion 200 and the pressure plate 4 are symmetrically arranged in two groups along the vertical plane where the axis of the ball screw 6 is located, thereby improving the balance of the linear guide rail 3 and the pressure plate 4 when subjected to force, thereby improving the operating stability of the drive device.

[0041] Specifically, because the linear guide 3, connecting portion 200, and pressure plate 4 are symmetrically arranged in two groups along the vertical plane of the ball screw 6 axis, the slide 1 can maintain high stability during sliding, reducing the occurrence of yaw. The symmetrical design ensures a more accurate and stable motion trajectory of the slide 1 during sliding, thereby improving the transmission and positioning accuracy of the device. Because the pressure plates 4 are symmetrically arranged on both sides of the slide 1, they can more evenly distribute the load generated by the slide 1 during sliding, enhancing the load-bearing capacity of the device.

[0042] Here, the direction perpendicular to the first direction and extending horizontally is defined as the second direction. Even if the slide 1 bears a torsional moment around the second direction, the torsional moment can be offset under the action of the first contact surface 100 and the second contact surface 400, so that the slide 1 can still maintain stable sliding, thereby ensuring the reliability of the composite sliding drive device.

[0043] Example 2:

[0044] Reference Figure 1-Figure 2 In addition to all the technical solutions of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0045] Two spaced apart connecting portions 200 extend from the base 2, forming an installation area between the two connecting portions 200. Two pressing plates 4 are provided and are detachably connected to the two connecting portions 200 in a one-to-one correspondence. The linear guide rail 3 and the slide 1 are both located in the installation area.

[0046] In this embodiment, the two connecting portions 200 are used to support and secure the pressure plate 4 and ensure a stable connection between the pressure plate 4 and the slide 1. The mounting area is used to mount other components so that the base 2 as a whole forms a protective shell that can protect these components, thereby improving the safety of the sliding device and making the layout of the various components of the sliding device more compact, thereby improving the overall structural compactness of the sliding device.

[0047] The number of both the connecting portion 200 and the pressing plate 4 is two, which can ensure the contact balance between the first contact surface 100 and the second contact surface 400 , thereby further improving the load bearing capacity of the slide 1 and improving the sliding stability of the slide 1 .

[0048] Example 3:

[0049] Reference Figure 1-Figure 2 In addition to all the technical solutions of any of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0050] The device further comprises a backing plate 5 connected between the pressing plate 4 and the connecting portion 200 to form a vertical spacing adjustment member between the first contact surface 100 and the second contact surface 400. The backing plate 5 is provided in various thicknesses; or, the backing plate 5 is an elastic plate.

[0051] In this embodiment, the pad 5 is connected between the pressure plate 4 and the connecting portion 200 to adjust the vertical distance between the first contact surface 100 and the second contact surface 400. This adjustment function ensures that the gap between the slide 1 and the pressure plate 4 is moderate during the sliding process, neither too tight to increase friction nor too loose to cause unstable sliding.

[0052] The backing plate 5 can be configured in two ways. One is to have multiple thicknesses, allowing the appropriate thickness to be selected based on actual needs to accommodate different working conditions and environments. For example, when the vertical load of the linear guide rail 3 and the pressure plate 4 increases after a period of use, a relatively thin backing plate 5 may be required to reduce the distance between the first contact surface 100 and the second contact surface 400. This allows the pressure plate 4 to squeeze the slide 1, thereby ensuring the slide 1's operational stability and load-bearing capacity.

[0053] Another method is to set the pad 5 as an elastic plate. By increasing or decreasing the force of the pressure plate 4 squeezing the pad 5, the thickness of the pad 5 can be adjusted, and then the distance between the first contact surface 100 and the second contact surface 400 can be flexibly changed, which can also ensure the operating stability and load-bearing capacity of the slide 1.

[0054] Specifically, the elastic pad 5 can be made of elastic materials such as rubber, spring steel, etc. These materials have good elasticity and recovery properties and can provide effective buffering and support during the sliding process of the slide 1.

[0055] A threaded hole is provided on the connecting portion 200 , and the backing plate 5 and the pressing plate 4 are detachably connected to the connecting portion 200 by bolts, thereby ensuring the connection reliability and convenience of the pressing plate 4 and the backing plate 5 on the connecting portion 200 .

[0056] Example 4:

[0057] Figure 1-Figure 2 In addition to providing a silicon rod grasping robot arm, the embodiment of the present invention includes the composite sliding drive device in any of the above embodiments, and also includes a fixed jaw and a movable jaw. The fixed jaw is connected to the base 2, and the movable jaw is connected to the slide 1. A clamping area capable of axially clamping the silicon rod is formed between the movable jaw and the fixed jaw.

[0058] In this embodiment, when a silicon ingot needs to be grasped, drive motor 8 is activated, driving ball screw 6 to rotate, which in turn drives slide 1 and the movable jaw toward the fixed jaw. Once the silicon ingot is gripped in the clamping area between the movable and fixed jaws, drive motor 8 stops, completing the grasping operation.

[0059] Since silicon rods are relatively heavy, a silicon rod grasping robot that uses the composite sliding drive device in any of the above-mentioned embodiments can be well adapted to the mass of the silicon rods. During the clamping process, the composite sliding drive device will not fail due to excessive load-bearing capacity or the torsional torque around the second direction, or suffer a significant reduction in lifespan and operating accuracy, thereby ensuring the safety and reliability of the silicon rod grasping robot.
