[0026] Example

[0027] Figure 1 FIG1 shows a schematic diagram of a three-dimensional structure of a movable workbench provided by an embodiment of the present invention. Figure 2 It is a partial enlarged schematic diagram of part A in Figure 1; Figure 3 FIG2 shows a schematic top view of a movable workbench provided by an embodiment of the present invention. Figure 4 FIG5 shows a bottom view of a movable workbench provided by an embodiment of the present invention. Figure 4 A partial enlarged schematic diagram of part B in the middle. Figure 6 FIG1 shows a schematic diagram of a left side view of a movable workbench provided by an embodiment of the present invention, Figure 7 FIG. 1 shows a schematic diagram of a three-dimensional structure of a movable substrate assembly provided by an embodiment of the present invention. Figures 1 to 7As shown, a movable workbench provided by an embodiment of the present invention includes: a fixed frame assembly 1, a movable base assembly 2, and a translation drive device 3. Specifically, the fixed frame assembly 1 is provided with two support rails 101 and a rack 102, and the movable base assembly 2 is provided with a workbench base 201 for installing a variety of tooling fixtures. A plurality of positioning holes and a plurality of mounting holes are provided on the workbench base 201 to adapt to the installation and fixation of a variety of tooling fixtures. A pin block 202 is provided below the workbench base 201 and is mechanically fixed to the workbench base 201. At least four support roller assemblies 203 are also provided and are mechanically connected to the workbench base 201. The movable base assembly 2 is connected to the support rail 101 in rolling contact through the support roller assembly 203, so that the support roller assembly 203 can roll along the upper surface of the support rail 101. The provision of at least four support roller assemblies 203 can ensure good support of the movable base assembly 2. The support positioning and movement are smooth. Of course, the support roller assembly 203 can also be set to 6, which can also achieve the above functions. There is no specific restriction on the number of the support roller assembly 203 here; the translation drive device 3 includes a driving gear 301, a driving cylinder 302, a connecting pin 303, and a driving motor 305. The driving motor 305 is driven and connected to the driving gear 301 to realize the rotation of the driving gear 301, and the driving gear 301 is connected to the rack 102 for gear transmission to realize the movement of the translation drive device 3. The driving motor 305 drives the driving gear 301 in the translation drive device 3 to rotate, so that the entire translation drive device 3 can move along the direction of the rack 102. By controlling the speed and start and stop of the driving motor 305, the speed and start and stop of the movement of the translation drive device 3 can be controlled. In addition, the driving cylinder 302 is driven and connected to the connecting pin 303 to realize the connecting pin 303 The translation drive device 3 is pinned to the pin block 202 via the connecting pin 303 to achieve the movement and locking of the movable base assembly 2 along the support guide rail 101. Specifically, when the driving cylinder 302 drives the connecting pin 303 to move upward, the connecting pin 303 is pinned to the pin block 202, and the translation drive device 3 can be connected to the movable base assembly 2. Therefore, when the driving motor 305 rotates, the translation drive device 3 and the movable base assembly 2 can move synchronously. When the driving motor 305 stops rotating, the translation drive device 3 and the movable base assembly 2 can stop synchronously and be locked and fixed. When the driving cylinder 302 drives the connecting pin 303 to move downward, the connecting pin 303 is disconnected from the pin block 202, and the translation drive device 3 can be disconnected from the movable base assembly 2, so that they can be adjusted and maintained separately.

[0028] In a mobile workbench provided in an embodiment of the present invention, the translation drive device 3 also includes at least two sliders 306, and the fixed frame assembly 1 is also provided with a fixed base plate 104 and two slide rails 105. The two slide rails 105 are mechanically fixed to the fixed base plate 104 respectively, and the sliders 306 are slidably connected with the slide rails 105. At least one slider 306 is installed on each slide rail 105. The sliders 306 and the slide rails 105 are used to achieve precise positioning of the translation drive device 3 to achieve uniaxial movement of the translation drive device 3. The smooth movement of the translation drive device 3 is achieved by the sliders 306 and the slide rails 105. The cross-sectional shape of the slider 306 here is adapted to the cross-sectional shape of the slide rail 105. The cross-sectional shape of the slider 306 and the cross-sectional shape of the slide rail 105 can be triangular, trapezoidal, I-shaped or a combination of the above figures, including but not limited to the above figures, as long as the slider 306 can achieve uniaxial sliding along the direction of the slide rail 105 and ensure the support positioning of the slider 306.

[0029] In a mobile workbench provided in an embodiment of the present invention, the translation drive device 3 also includes a guide gear 304, which is connected to the rack 102 through gear transmission. Here, the guide gear 304 only plays a guiding role to prevent the translation drive device 3 from having a large position offset during movement.

[0030] In a movable workbench provided in an embodiment of the present invention, the movable base plate assembly 2 is further provided with at least four guide rollers 204, which are mechanically connected to the support roller assembly 203. Each support roller assembly 203 is equipped with at least one guide roller 204. In the embodiment of the present invention, each support roller assembly 203 is equipped with two guide rollers 204. Figure 6 The specific installation of two guide rollers 204 is shown, wherein the guide rollers 204 are connected to the side surfaces of the support rail 101 in rolling contact to achieve the guiding positioning of the movable substrate assembly 2. The contact positioning between the guide rollers 204 and the support rail 101 prevents the movable substrate assembly 2 from positional displacement during movement along the support rail 101, thereby ensuring the movement accuracy of the movable substrate assembly 2.

[0031] In a mobile workbench provided in an embodiment of the present invention, it also includes at least two positioning buffer assemblies 4, which are mechanically fixed to the fixed base plate 104, and multiple positioning buffer assemblies 4 are respectively arranged at the left and right ends of the mobile workbench to realize positioning buffering of the movable substrate assembly 2; here, two positioning buffer assemblies 4 are respectively arranged at the left and right ends of the mobile workbench to ensure uniform force on the movable substrate assembly 2, and at the same time, the positioning buffer assembly 4 can limit the position of the movement stroke of the movable substrate assembly 2, and the positioning buffer assembly 4 is provided with buffer components. The material of the buffer components can be rubber pads, nylon and other materials, including but not limited to the above materials, to prevent the movable substrate assembly 2 and the positioning buffer assembly 4 from generating rigid collision at the end of the stroke to cause damage to the components.

[0032] In a movable workbench provided in an embodiment of the present invention, it also includes a first travel switch 5 and a second travel switch 6. The first travel switch 5 and the second travel switch 6 are respectively arranged at the left and right ends of the movable workbench to realize the position identification of the movable substrate assembly 2. Through the left and right movement of the movable substrate assembly 2, it contacts the first travel switch 5 or the second travel switch 6 at the end of its movement stroke, so that the first travel switch 5 or the second travel switch 6 sends a signal, so that the external control system can identify the specific position of the movable substrate assembly 2, which is more suitable for the overall logic control of the automated production line, enhances the safety and reliability of the production line, and prevents misoperation.

[0033] As a further improvement of a movable workbench provided in an embodiment of the present invention, the fixed frame assembly 1 is further provided with at least one calibration block 103, which is in contact with the side of the support rail 101. The position of the calibration block 103 can be adjusted to achieve position calibration of the support rail 101. By adjusting the adjustment screw on the calibration block 103, the calibration block 103 can squeeze the support rail 101 to achieve position adjustment of the support rail 101, thereby ensuring that the straightness and parallelism indicators of the two support rails 101 meet the use requirements, so that the movable base plate assembly 2 can achieve normal movement on the support rail 101, ensuring the movement accuracy and preventing jamming. Here, the calibration block 103 is positioned lower than the guide roller 204, that is, the upper surface of the calibration block 103 is lower than the lowermost surface of the guide roller 204, to prevent the calibration block 103 from causing position interference with the guide roller 204 when it moves along the support rail 101.

[0034] Compared with the prior art, the mobile workbench provided by the present invention has a reasonable design, a simple structure, convenient adjustment, and high precision. The smooth movement of the movable base plate assembly 2 is achieved through the translation drive device 3. It is convenient to connect through the connecting pin 303 and can adapt to the fixation and position adjustment of various tooling fixtures, thereby expanding the application of the mobile workbench. It has strong versatility and a large motion stroke. The movement of the movable base plate assembly 2 can save operating space, meet the various needs of users, and can be widely used in manufacturing industries such as automobiles, ships, aerospace, and large machinery.
