Description

Technical Field

[0001] This utility model relates to the field of machine tool processing technology, specifically to a precision cutting device for machining machine tool guards. Background Technology

[0002] Machine tool protective covers are used to protect machine tool guideways. They can protect the internal hardened guideways, linear guideways, ball screws, or transmission racks of the machine tool from external corrosion and damage.

[0003] For example, patent CN211465568U discloses a precision cutting device for machining machine tool guards. In order to improve the accuracy of machine tool guard cutting, a cutting mechanism is fixed to the telescopic end of the hydraulic rod. A transverse cutting machine is fixed to one end of the cutting mechanism, and a longitudinal cutting machine is symmetrically fixed to the other end of the cutting mechanism. Support plates are fixed at both the front and rear ends of the support frame. The support plates are fixed to the mechanism.

[0004] With the above setup, the existing technology uses a cutting mechanism to drive the lifting and sliding of the transverse and longitudinal cutting machines, and a drive motor to drive the horizontal movement of the support frame. This replaces the traditional single-cutting method, enabling all-around cutting of the machine tool cover while ensuring data accuracy during the cutting process. The fastening mechanism for securing the machine tool cover facilitates the positioning and handling of the cover by the operator. However, the existing precision cutting device for machine tool cover processing has the following drawbacks during operation:

[0005] In the above-mentioned technical solution, when cutting the machine tool cover, the cover is placed on a support plate, and then the fastening handwheel is turned to drive the fastening screw to tighten and rotate in the positioning screw sleeve. Simultaneously, the fastening block is raised and lowered, and the NBR material fastening block is used to press and fix the machine tool cover. However, this method is not only cumbersome to fix, but it can only fix the four corners of the cover, while the center of the cover will not be fixed. When cutting the cover, the device will generate vibration, which will cause vibration ripples on the machined surface, resulting in a rough surface. This will affect the normal movement trajectory and cause the machined surface to have wrinkled silk-like or fish-scale-like shapes, thus reducing the quality and dimensional accuracy of the machined surface. Utility Model Content

[0006] The present invention aims to provide a precision cutting device for machining machine tool covers, which is mainly used to solve the technical problems of cumbersome and unstable fixing of machine tool covers in the prior art.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A precision cutting device for machining machine tool guards includes a worktable, characterized in that a movable seat is slidably connected to the top of the worktable, a rectangular groove is formed on the top of the movable seat, a plurality of mounting holes are symmetrically formed on the outer side wall of the movable seat, the mounting holes are connected to the rectangular groove, a pneumatic component is fixedly connected to the bottom of the rectangular groove, a support frame is symmetrically fixedly connected to the top of the movable seat, a clamping block is slidably connected to the outer side wall of the support frame, a pressure boosting component is fixedly connected to the outer side wall of the movable seat at the mounting holes, and a locking component is fixedly connected to the outer side wall of the movable seat at the support frame.

[0009] The working principle and beneficial effects of this utility model:

[0010] 1. Working Principle: The structure of the precision cutting device for machine tool cover processing in this utility model is similar to that of existing precision cutting devices for machine tool cover processing, such as the precision cutting device for machine tool cover processing disclosed in patent publication number CN211465568U. The main improvement of this utility model is that when the machine tool cover needs to be cut, the machine tool cover is first placed inside the rectangular groove, and then the pressurizing component works, which drives the locking component to work. When the locking component works, it drives the clamping block to slide down along the outer wall of the support frame, thereby fixing the machine tool cover inside the rectangular groove through the clamping block. During the operation of the pressurizing component, the air pressure inside the pneumatic component is reduced, which tightly sucks the machine tool cover, completing the fixing of the machine tool cover, and then the cutting work is performed on the cover body.

[0011] 2. Beneficial effects:

[0012] Existing technology addresses the challenge of omnidirectional cutting of machine tool covers by incorporating a cutting mechanism that drives the lifting and sliding of horizontal and vertical cutting machines, along with a drive motor that moves the support frame horizontally. This replaces the traditional single-cutting method. However, existing technology suffers from cumbersome and unstable fixing of the machine tool cover. This solution addresses this by using a pressurizing component that simultaneously drives the locking and pneumatic components, achieving greater convenience. When the locking component is in operation, it causes the clamping block to slide downwards along the outer wall of the support frame, thus fixing the machine tool cover inside the rectangular slot. The pressurizing component then reduces the internal air pressure of the pneumatic component, tightly gripping the machine tool cover and completing its fixation. The cover body is then cut, thus avoiding the problem of cover vibration during the cutting process.

[0013] Preferably, the pneumatic assembly includes a housing fixedly connected to the bottom of a rectangular groove. Multiple air vents are provided on the top of the housing. A C-shaped tube is fixedly connected to the outer wall of the movable seat, and an L-shaped tube is fixedly connected to the inner wall of the mounting hole. One end of the L-shaped tube communicates with the side wall of the housing, and the other end communicates with the outer wall of the C-shaped tube. When the protective cover is placed on top of the housing, air is drawn outwards from the C-shaped tube, causing the internal air pressure of the housing to continuously decrease. As the internal air pressure decreases, external air enters the housing through the air vents. With the continuous drawing of air from the C-shaped tube, the external atmospheric pressure presses the protective cover tightly against the housing, thus fixing the bottom of the protective cover and preventing it from shaking during the cutting process.

[0014] Preferably, the pressurization assembly includes an air pump fixedly connected to the outer wall of the movable seat. The output end of the air pump is fixedly connected to a connecting pipe, and the end of the connecting pipe is connected to the outer wall of the C-shaped tube. When it is necessary to draw air from the C-shaped tube, the air pump is turned on, and the air pump draws air from the C-shaped tube through the connecting pipe, thereby achieving a convenient purpose.

[0015] Preferably, the locking assembly includes a sleeve fixedly connected to the outer wall of the movable seat, a push block slidably connected to the inner wall of the sleeve, a piston fixedly connected to the bottom of the push block, a movable rod fixedly connected to the top of the push block, the top of the movable rod being fixedly connected to the bottom of the clamping block, a connecting pipe fixedly connected to the bottom of the sleeve, and the bottom of the connecting pipe communicating with the outer wall of the C-shaped tube. When the air pump is working, the C-shaped tube extracts the gas inside the sleeve through the connecting pipe, and the air pressure inside the sleeve continuously decreases. Under the larger air pressure outside, the movable rod pushes the push block and the piston to slide on the inner wall of the sleeve. As the movable rod moves downward, it drives the clamping block to slide downward along the outer wall of the support frame, thereby fixing the machine tool cover to the top of the housing through the clamping block, achieving the effect of quickly fixing the machine tool cover.

[0016] Preferably, the length of the support frame is much greater than the length of the movable rod to prevent the clamping block from detaching from the support frame when the movable rod rises after processing.

[0017] Preferably, the bottom of each clamping block is fixedly connected with a rubber block. The rubber block can not only increase the stability between the clamping block and the protective cover, but also prevent wear on the protective cover during the clamping process.

[0018] Preferably, both the sleeve and the housing are connected to a C-shaped tube. When it is necessary to fix the protective cover, the air pump can be started to simultaneously extract the gas inside the sleeve and the housing, achieving a synchronous effect. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-4As shown, the device includes a workbench 1. The workbench 1 has a sliding seat 3 slidably connected to its top. A rectangular groove 10 is formed on the top of the sliding seat 3. Multiple mounting holes 5 are symmetrically formed on the outer side wall of the sliding seat 3, communicating with the rectangular groove 10. A pneumatic assembly is fixedly connected to the bottom of the rectangular groove 10. The pneumatic assembly includes a housing 4 fixedly connected to the bottom of the rectangular groove 10. Multiple air outlets 11 are formed on the top of the housing 4. A C-shaped tube 6 is fixedly connected to the outer side wall of the sliding seat 3. An L-shaped tube 8 is fixedly connected to the inner side wall of the mounting holes 5. One end of the L-shaped tube 8 communicates with the side wall of the housing 4, and the other end of the L-shaped tube 8 communicates with the C-shaped tube 6. The outer wall of the C-shaped tube 6 is open, and air is drawn outward from the inside of the C-shaped tube 6, causing the air pressure inside the box 4 to continuously decrease. As the air pressure inside the box 4 continuously decreases, external air will enter the inside of the box 4 through the air outlet 11. With the continuous drawing of air from the C-shaped tube 6, the external atmospheric pressure will press the protective cover and the box 4 tightly together, achieving the purpose of fixing the bottom of the protective cover. The top of the movable base 3 is symmetrically fixedly connected to the support frame 12, and the outer wall of the support frame 12 is slidably connected to the clamping block 15. The outer wall of the movable base 3 located at the mounting hole 5 is fixedly connected to the pressurizing component, which includes components fixedly connected to the movable base. An air pump 2 is mounted on the outer wall of the 3rd side. A connecting pipe 7 is fixedly connected to the output end of the air pump 2. The end of the connecting pipe 7 is connected to the outer wall of the C-shaped tube 6. When the air pump 2 is turned on, it draws air from the C-shaped tube 6 through the connecting pipe 7. A locking assembly is fixedly connected to the outer wall of the movable seat 3 located at the support frame 12. The locking assembly includes a sleeve 13 fixedly connected to the outer wall of the movable seat 3. A push block 17 is slidably connected to the inner wall of the sleeve 13. A piston 16 is fixedly connected to the bottom of the push block 17. A movable rod 14 is fixedly connected to the top of the push block 17. The top of the movable rod 14 is connected to the bottom fixed section of the clamping block 15. The bottom of the sleeve 13 is fixed... A connecting pipe 9 is connected, and the bottom of the connecting pipe 9 is connected to the outer wall of the C-shaped pipe 6. The C-shaped pipe 6 extracts the gas inside the sleeve 13 through the connecting pipe 9. At this time, the air pressure inside the sleeve 13 continuously decreases, while the larger air pressure outside causes the movable rod 14 to push the push block 17 and the piston 16 to slide on the inner wall of the sleeve 13. As the movable rod 14 moves downward, it drives the clamping block 15 to slide downward along the outer wall of the support frame 12, thereby fixing the machine tool cover to the top of the housing 4 through the clamping block 15. The rubber block 18 prevents damage to the cover during the clamping process, achieving the effect of quickly fixing the machine tool cover.

[0026] As can be seen from the above, the specific embodiments of this utility model are as follows:

[0027] When this device needs to cut the machine tool cover, it first places the machine tool cover inside the rectangular slot 10, turns on the air pump 2, and the air pump 2 draws air from the C-shaped tube 6 through the connecting pipe 7. As the gas is drawn out from the inside of the C-shaped tube 6, the air pressure inside the housing 4 continuously decreases. With the air pressure inside the housing 4 continuously decreasing, external gas enters the housing 4 through the air outlet 11. As the C-shaped tube 6 continues to draw air, the external atmospheric pressure presses the cover tightly against the housing 4, achieving the purpose of fixing the bottom of the cover. At the same time, the C-shaped tube 6 extracts the gas inside the sleeve 13 through the connecting tube 9. At this time, the air pressure inside the sleeve 13 continuously decreases, while the larger air pressure outside causes the movable rod 14 to push the push block 17 and piston 16 to slide on the inner wall of the sleeve 13. As the movable rod 14 moves downward, it drives the clamping block 15 to slide downward along the outer wall of the support frame 12, thereby fixing the machine tool cover to the top of the housing 4 through the clamping block 15. The rubber block 18 prevents damage to the cover during the clamping process, achieving the effect of quickly fixing the machine tool cover.
