Description

Technical Field

[0001] This utility model relates to the field of machine tool technology, specifically to a CNC machine tool fixture installation mechanism. Background Technology

[0002] CNC machine tools typically have a machining head on their worktable, as well as a fixture to hold the workpiece. Some worktables use hydraulic tailstocks and chucks to hold the workpiece for subsequent processing. During the processing, coolant is used, which generates a lot of processing waste liquid. This waste liquid usually carries the processing residue with it and flows down to the worktable, where it is finally collected.

[0003] Since the hydraulic tailstock and chuck clamp are mounted on the base above the worktable using bolts and other connecting parts, a connecting groove (one or more grooves along the length) is provided on the base to facilitate adjustment of the distance between them, as shown in the instruction manual. Figure 1 As shown, these connection grooves are usually located on the upper surface, and waste liquid flowing down from above can easily enter them. Waste chips and slag generated during processing can also easily splash into the grooves. The waste that enters them is not easy to discharge, which can easily clog the grooves, and subsequent cleaning is also quite troublesome. Summary of the Invention

[0004] The purpose of this utility model is to address the problems existing in the prior art by providing a CNC machine tool fixture installation mechanism.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A CNC machine tool fixture installation mechanism includes a support base mounted on a machine tool worktable. The support base has a chuck fixture seat and a tailstock body arranged opposite to each other. A pair of sliding plates are provided on the support base, connecting the chuck fixture seat and the tailstock body. The front and back side walls of the support base are respectively provided with sliding grooves. Both ends of the sliding plates are slidably connected to the sliding grooves. The sliding plates are detachably connected to the front side wall of the support base via fasteners. The back side wall of the support base has a drainage structure communicating with the sliding grooves.

[0007] This CNC machine tool fixture installation mechanism improves its moving connection method by setting the slide groove and connecting structure on the side wall of the support base, keeping the upper surface of the support base flat. This prevents waste liquid and slag generated during machine tool processing from entering the grooves on the upper surface of the support base, and also reduces the amount of waste liquid and slag entering the slide groove or connecting structure on the side wall. This design reduces the accumulation of slag, especially metal powder, in the slide groove to avoid affecting the movement of the slide plate, and also reduces the amount of cleaning work after processing. Moreover, the entire installation mechanism has a simple structure and is easy to install and use.

[0008] Furthermore, the slide plate includes a horizontal support plate, with vertical side arms symmetrically arranged on both sides of the horizontal support plate. A sliding arm is provided on the inner side of the vertical side arm, and the sliding arm is slidably connected in the slide groove. The chuck clamp seat and the tailstock body are mounted on the horizontal support plate, and a clearance gap is provided between the lower surface of the horizontal support plate and the upper surface of the support base.

[0009] Furthermore, gaskets are provided between the vertical side arm and the front and back side walls of the support base, and rollers or omnidirectional balls are provided below the horizontal support plate to support the support base, which can further play the role of rolling support.

[0010] Furthermore, the front sidewall of the support base is also provided with a T-shaped groove arranged parallel to the slide groove. The fastener is a fastening bolt that connects the slide plate and the T-shaped groove. Each slide plate is connected to multiple fastening bolts to facilitate the fixing of the slide plate.

[0011] Furthermore, the drainage structure includes multiple vertical channels disposed on the back sidewall of the support base. The vertical channels are connected to the chute, and the connection between the vertical channels and the chute is provided with a rounded chamfer so that the waste liquid carries the waste residue to the vertical channels.

[0012] Furthermore, the slide groove is arranged through the length of the support base, and detachable limiting blocks are provided at both ends of the slide groove to limit the movement at the ends.

[0013] Furthermore, the chuck clamp seat and the tailstock body are respectively connected to the slide plate by connecting bolts, and the chuck clamp seat and the tailstock body have a coaxial horizontal central axis.

[0014] Furthermore, the upper surface of the support base is provided with a slope of 1 to 3 degrees, and the slope is arranged inclined from the front to the back of the support base.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. By improving its movable connection method, this CNC machine tool fixture installation mechanism sets the slide groove and connecting structure on the side wall of the support base, keeping the upper surface of the support base flat. This prevents waste liquid and slag generated during machine tool processing from entering the grooves on the upper surface of the support base, and also reduces the amount of waste liquid and slag entering the slide groove or connecting structure on the side wall. This arrangement can reduce the accumulation of slag, especially metal powder, in the slide groove to avoid affecting the movement of the slide plate, and also reduces the amount of cleaning work after processing; moreover, 1. The entire installation mechanism has a simple structure and is easy to install and use; 2. Few waste liquids and waste residues will enter the front sidewall of the support base. Therefore, connecting the fasteners to the front sidewall can effectively prevent waste liquids or waste residues from entering the connection position. Moreover, placing the fasteners on the front makes operation convenient and facilitates their installation and disassembly; 3. The drainage structure is further provided on the back sidewall of the support base, which can guide the outflow of waste liquids in the chute. During the outflow of waste liquids, waste residues will also be carried away. When the slide plate moves, the waste liquids or waste residues accumulated in the chute can also be pushed towards the drainage structure, which can prevent waste liquids and waste residues from clogging the chute.

[0024] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Example 1

[0026] like Figures 2-5 As shown, a CNC machine tool fixture installation mechanism includes a support base 2 mounted on a machine tool worktable 1. The support base 2 is provided with a chuck fixture seat 3 and a tailstock body 4 arranged opposite to each other. The support base 2 is provided with a pair of sliding plates 5, which connect and install the chuck fixture seat 3 and the tailstock body 4. The front sidewall and the back sidewall of the support base 2 are respectively provided with a sliding groove 6. The two ends of the sliding plate 5 are respectively slidably connected to the sliding groove 6. The sliding plate 5 is detachably connected to the front sidewall of the support base 2 by fasteners 8. The back sidewall of the support base 2 is provided with a drainage structure communicating with the sliding groove 6.

[0027] This CNC machine tool fixture installation mechanism improves its moving connection method by setting the slide groove 6 and the connecting structure on the side wall of the support base 2, keeping the upper surface of the support base 2 flat. This prevents waste liquid and slag generated during the machine tool's processing from entering the grooves on the upper surface of the support base, and also reduces the amount of waste liquid and slag entering the slide groove or connecting structure on the side wall. This design reduces the accumulation of slag, especially metal powder, in the slide groove to avoid affecting the movement of the slide plate, and also reduces the amount of cleaning work after processing. Moreover, the entire installation mechanism has a simple structure and is easy to install and use.

[0028] The sliding plate 5 can independently support and install the chuck fixture seat 3 and the tailstock body 4 without the need for these two seats to be directly connected and fixed to the support base 2. The sliding plate 5 can drive the chuck fixture seat and the tailstock body to move through the sliding cooperation of the sliding groove 6, thereby adjusting the distance between them so as to better clamp the workpiece to be processed.

[0029] Because the chute 6 is located on both sides of the support base 2, waste liquid and waste residue will not fall into the chute from top to bottom as in the original structure. This can significantly reduce the amount of waste liquid and waste residue entering the chute 6. Basically, only some waste liquid or waste residue will splash into the back side wall, and very little waste liquid or waste residue will enter the front side wall. Therefore, connecting the fastener 8 to the front side wall can effectively prevent waste liquid or waste residue from entering the connection position. Moreover, placing the fastener 8 on the front makes it easy to operate and facilitates its installation and disassembly.

[0030] The drainage structure is further provided on the back side wall, which can guide the outflow of waste liquid in the chute 6. During the outflow of waste liquid, waste residue will also be carried away. When the slide plate moves, the waste liquid or waste residue accumulated in the chute can also be pushed towards the drainage structure, which can prevent waste liquid and waste residue from clogging the chute.

[0031] Furthermore, the slide plate 5 includes a horizontal support plate 501, with vertical side arms 502 symmetrically arranged on both sides of the horizontal support plate 501. A sliding arm 503 is provided on the inner side of the vertical side arm 502. The sliding arm 503 is slidably connected in the slide groove 6. The chuck clamp seat 3 and the tail seat body 4 are installed on the horizontal support plate 501. A clearance gap is provided between the lower surface of the horizontal support plate 501 and the upper surface of the support base 2.

[0032] The slide plate 5 is similar to an inverted U-shaped structure. The horizontal support plate 501 is arranged parallel to the machine tool worktable, on which the chuck fixture seat and the tailstock body can be installed. The vertical side arms 502 on both sides serve as lateral limiting and are also used to set the slide arms 503, allowing the slide arms 503 to connect in the slide groove 6. By moving the horizontal support plate 501, the slide arms 503 can move along the slide groove 6. During the movement, the slide arms 503 can also act as scrapers to scrape the residue in the slide groove 6 to the drainage structure. The slide arms 503 and the slide groove 6 can also provide a certain degree of support. The vertical side arms on the front can be connected to the front side wall through the fasteners 8 to fix the slide plate 5.

[0033] The clearance not only reduces the contact area between the slide plate and the support base, thus reducing friction, but also forms a flow channel to allow waste liquid above the support base to flow out, and facilitates subsequent cleaning.

[0034] Furthermore, the front sidewall of the support base 2 is also provided with a T-slot 7 arranged parallel to the slide 6. The fastener 8 is a fastening bolt that connects the slide plate and the T-slot 7. Each slide plate 5 is connected to multiple fastening bolts. The T-slot 7 and the fastening bolts facilitate the fixing of the slide plate.

[0035] Furthermore, shims 9 are provided between the vertical side arm 502 and the front and back side walls of the support base 2, respectively. By setting these shims 9, the gap between the left and right sides can be adjusted, and the tightness and stability of the connection can be improved after the fastening bolts are connected.

[0036] Furthermore, the drainage structure includes multiple vertical flow channels 10 disposed on the back sidewall of the support base 2, the vertical flow channels 10 connecting to the slide groove 6 on the back side, and the connection between the vertical flow channels 10 and the slide groove 6 is provided with a rounded chamfer 11.

[0037] The arrangement of these vertical flow channels 10 facilitates the downward flow of waste liquid in the chute, guiding it to the worktable. The arrangement of the rounded chamfer 11 can reduce stress concentration and avoid accumulation and jamming, which is conducive to the downward flow of waste liquid.

[0038] Furthermore, the slide groove 6 is arranged through the length of the support base 2, which allows the slide plate 5 to move and adjust along the entire length direction, and the slide plate 5 can also be installed on the support base 2 from both ends; the two ends of the slide groove 6 are also provided with detachable limiting blocks 12, which serve as end limiting blocks. The limiting blocks 12 can be fixed by screws, and the limiting blocks can be removed when the slide plate needs to be disassembled.

[0039] Furthermore, the chuck fixture 3 and the tailstock body 4 are respectively connected to the slide plate 5 by connecting bolts. The chuck fixture 3 and the tailstock body 4 have a coaxial horizontal central axis, which helps to maintain coaxiality. The workpiece to be processed is placed between the two, with one end clamped by the fixture on the chuck fixture 3 and the other end supported by the center point on the tailstock body. After adjusting the position and clamping force, processing can begin.

[0040] On the left side of the support base 2, that is, on the back side of the machine tool worktable 1, there is a slide system. The slide system is equipped with components such as columns and grinding heads to process the clamped workpiece. Example 2

[0041] The difference between this embodiment and Embodiment 1 is that a support structure is provided under the skateboard.

[0042] Specifically, such as Figure 6 As shown, a universal ball bearing 13 is provided below the horizontal support plate 501 and supported on the support base 2. The universal ball bearing 13 is installed below the slide plate 5 through a ball bearing seat, and the universal ball bearing 13 is freely supported on the upper surface of the support base 2. This arrangement helps to improve the support stability of the slide plate 5 and eliminates the need for a groove structure on the upper surface of the support base 2. Example 3

[0043] The difference between this embodiment and Embodiment 1 lies in the different structure of the support base.

[0044] Specifically, such as Figure 7 As shown, the upper surface of the support base 2 is provided with a slope of 1 to 3 degrees 14. The slope 14 is arranged inclined from the front to the back of the support base 2, that is, inclined from the right to the left in the width direction. This is conducive to the waste liquid and waste residue falling on the upper surface flowing to the left and preventing the waste liquid and waste residue from flowing to the front of the machine tool worktable.

[0045] On this sloping support base 2, two rollers 15 can be installed below the horizontal support plate 501. The rollers 15 have slightly different heights, so that the slide plate 5 can be supported on the sloping surface without affecting its movement.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
