Description

Technical Field

[0001] This utility model relates to the field of machine tool table technology, and in particular to a machine tool table with vacuum adsorption. Background Technology

[0002] The machine tool table is a key component of a machine tool, primarily used to fix the workpiece and provide a stable working surface for machining. Currently, there are various methods for fixing machine tool tables. A common, fast, and convenient method is vacuum adsorption. Vacuum adsorption is a technology that uses the principle of vacuum to adsorb and fix the workpiece, and it is widely used in machine tool processing, automated production lines, and material handling systems. By fixing the workpiece to the machine tool table using the principle of vacuum adsorption, stability and accuracy during machining are ensured, machining efficiency is improved, and adaptability to workpieces of different shapes and sizes is enhanced.

[0003] The machine tool table with vacuum adsorption disclosed in CN220463080U, through the setting of piston, spring and sealing ring one, enables the machine tool table to automatically adjust the adsorption range according to the shape of the plate, making the plate fixation more convenient; through the setting of sealing ring two and filter, impurities cannot enter the adsorption hole, avoiding impurities affecting the normal operation of the piston; sealing ring two seals the gap between the plate and the table, thus making the adsorption and fixation of the plate more reliable; through the setting of base plate, cavity and sealing strip, the top of the base plate forms a cavity, thus reducing the difficulty of machining the cavity and adsorption hole of the machine tool table; sealing strip effectively seals the base plate and the table body.

[0004] However, when the volume of the part to be processed is larger than the overall area of ​​the device, the area of ​​the utility model is fixed, which is not convenient for quick assembly and may require the replacement of the table, reducing the versatility and convenience of the device; the adsorption holes of the device are directly opened on the table, which is inconvenient when cleaning dust under the filter, etc., and the spring elasticity decreases after long-term use. The adsorption hole opening of the device is narrow, which is not convenient for the maintenance of internal parts. Utility Model Content

[0030] Example 1

[0031] Reference Figure 1-5 This is the first embodiment of the present invention, which provides a machine tool table with vacuum adsorption. This structure includes:

[0032] The tabletop body 100 has a cavity inside, and a vacuum pipe 101 is fixedly installed in the cavity. A vacuum pump is connected to the vacuum pipe 101 through the connection port 1011 on the vacuum pipe 101, which reduces the number of external interfaces and effectively prevents the vacuum pipe 101 from being blocked by waste during the processing.

[0033] The fixing component 200 includes a first fixing block 201 and a second fixing block 202. The second fixing block 202 is fixedly installed on one side of both ends of the table body 100 and has an arc-shaped groove. The first fixing block 201 is fixedly installed on the other side of both ends of the table body 100 and has a sliding groove. An arc-shaped block 203 is slidably connected in the sliding groove. A control block 204 is fixedly connected to the arc-shaped block 203. Limiting strips 205 are fixedly connected to both sides of the arc-shaped block 203. During use, when the area of ​​the workpiece is large, multiple table bodies 100 can be spliced ​​together. The first fixing block 201 and the second fixing block 202 at two adjacent parts of the table body 100 are engaged. At this time, rotating the control block 204 can drive the arc-shaped block 203 to rotate along the sliding groove, so that the arc-shaped block 203 is inserted into the arc-shaped groove. At this time, the first fixing block 201 and the second fixing block 202 are closed, so that the two table bodies 100 can be quickly spliced ​​together.

[0034] The adsorption assembly 300 includes an installation tube 301. A filter sheet 302 is attached to the top of the inner wall of the installation tube 301, and a first rubber ring 303 is attached to the bottom of the inner wall of the installation tube 301. A spring 304 is fixedly installed on the inner bottom wall of the installation tube 301, and a piston 305 is fixedly connected to the top of the spring 304. During use, after the workpiece is placed on the table body 100, an external vacuum pump is connected through the connection port 1011 to extract the air from the vacuum pipe 101, creating a negative pressure in the adsorption port 1013 and the installation tube 301. When the workpiece is fixed in place, the piston 305 is pulled down by suction and presses against the first rubber ring 303, preventing air leakage from the installation tube 301 that is not covered by the workpiece. When dust accumulates in the installation tube 301 or the parts are damaged and need repair, the installation tube 301 can be removed from the adsorption hole to facilitate cleaning of the filter 302 and repair of the internal mechanical structure. After repair, the installation tube 301 is inserted into the adsorption hole, and the locking block 3011 is inserted into the locking slot, so that the installation tube 301 is fixed on the table body 100.

[0035] Furthermore, a connection port 1011 is provided at one end of the vacuum pipe 101, and a valve 1012 is provided on the connection port 1011. The air flow at the connection port 1011 is controlled by the valve 1012. The air in the vacuum pipe 101 can be extracted by connecting a vacuum pump to the connection port 1011.

[0036] Furthermore, the vacuum pipe 101 is provided with an adsorption port 1013, and a second rubber ring 1014 is provided at the top of the adsorption port 1013. The adsorption port 1013 is connected to the installation pipe 301, and the second rubber ring 1014 increases the sealing degree at the connection between the adsorption port 1013 and the installation pipe 301.

[0037] Furthermore, a pressure gauge 1015 is installed on the vacuum pipe 101 to monitor the vacuum level inside the vacuum pipe 101.

[0038] Furthermore, the top of the tabletop body 100 is provided with an adsorption hole, and the side wall of the adsorption hole is provided with a slot. A locking block 3011 is slidably connected in the slot. The locking block 3011 is fixedly installed on the surface of the mounting tube 301. By inserting the locking block 3011 into the slot, the mounting tube 301 is fixed in the adsorption hole, preventing the mounting tube 301 from rotating in the adsorption hole and causing wear on the inner wall.

[0039] Furthermore, the inner bottom wall of the mounting tube 301 is provided with a vent hole, through which air can be easily extracted from the mounting tube 301, so that a negative pressure state is formed inside the mounting tube 301.

[0040] During use, when the area of ​​the workpiece is large, multiple tabletop bodies 100 can be spliced ​​together. The first fixing block 201 and the second fixing block 202 at two adjacent tabletop bodies 100 engage. At this time, rotating the control block 204 can drive the arc-shaped block 203 to rotate along the slide groove, so that the arc-shaped block 203 is inserted into the arc groove. At this time, the first fixing block 201 and the second fixing block 202 close, so that the two tabletop bodies 100 can be spliced ​​together quickly.

[0041] Then, after placing the workpiece on the table body 100, the air in the vacuum pipe 101 is extracted by an external vacuum pump connected through the connection port 1011, so that a negative pressure is formed in the adsorption port 1013 and the mounting tube 301 to fix the workpiece. At this time, the piston 305 is pulled down by suction and sticks tightly to the first rubber ring 303, so that air can be prevented from leaking into the mounting tube 301 that is not covered by the workpiece.

[0042] Finally, when dust accumulates inside the installation tube 301, or when parts are damaged and require repair, the installation tube 301 can be removed from the adsorption hole, which facilitates the cleaning of the filter 302 and the repair of the internal mechanical structure. After repair, the installation tube 301 is inserted into the adsorption hole, and the locking block 3011 is inserted into the locking slot, which fixes the installation tube 301 onto the tabletop body 100.

[0043] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
