Description

Technical Field

[0001] This utility model relates to the field of machine tool processing technology, specifically to a chip removal device for machining differential housings. Background Technology

[0002] A differential is a mechanical device in a car that allows the left and right or front and rear drive wheels to rotate at different speeds. It is mainly used to solve the problem of the difference in speed between the inner and outer wheels when the vehicle is turning. The differential housing needs to be machined by a machine tool, such as drilling. A CNC machine tool is an automated machine tool equipped with a program control system. It can make the machine tool move and process parts according to a pre-programmed program. During the processing, chips are generated on the worktable and need to be cleaned.

[0003] The existing patent publication number CN220660092U discloses a chip cleaning device. By rotating a threaded rod driven by a handle, the threaded rod squeezes a brush, which slides and cleans the surface of the workbench, pushing the dust on the workbench surface into the housing. Then, the threaded rod can be retracted by reversing the handle. By setting up a cleaning device, the workbench surface is effectively cleaned, which increases the ease of use of the equipment, reduces the difficulty of operation, facilitates use, and improves the safety of the equipment. By setting up a protective device, the chips generated during processing are effectively blocked.

[0004] The aforementioned patent describes a device that uses a threaded rod to drive a brush to slide across the worktable to clean up chips, reducing the difficulty of operation and making it convenient to use. However, it requires continuous rotation of the handle, and once the brush has slid to one end, the handle needs to be reversed to reset the brush. Continuous rotation of the handle can easily cause hand fatigue for the operator, resulting in low efficiency and inconvenience. Furthermore, the protective device only blocks the front side, allowing chips to easily splash out from other unblocked surfaces, increasing the difficulty of cleaning. Utility Model Content

[0023] 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.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The present invention provides a technical solution: a chip cleaning device for machining differential housing, including a body 1 and a workbench 2 fixedly installed on the top of the body 1. The top of the workbench 2 has a sliding groove 3 with a front opening. A cleaning component 4 is slidably installed inside the sliding groove 3. A shielding component 5 is movably installed on the outer side of the top of the workbench 2. A chip discharge port 6 is opened on the front side of the top of the body 1.

[0025] The cleaning component 4 includes a frame 41 that is slidably inserted into the sliding groove 3. Two guide rods 42 are fixedly connected to the outer rear side wall of the frame 41. The rear ends of the guide rods 42 slide through the rear side wall of the workbench 2 and extend to the outside. A limit plate 43 is movably installed at the rear end of the guide rods 42. A return spring 44 located on the rear side of the workbench 2 is sleeved on the outer side of the rear end of the guide rods 42. The two ends of the return spring 44 are respectively connected to the rear side wall of the workbench 2 and the front side of the limit plate 43. Handles 45 are fixedly connected to both the left and right sides of the frame 41. The outer ends of the two handles 45 slide through the left and right sides of the sliding groove 3 and extend to the outside. A guide platform 46 is fixedly connected to the inner rear side wall of the frame 41. A cleaning brush 47 is fixedly installed at the bottom of the guide platform 46. The bottom of the cleaning brush 47 contacts and connects with the top surface of the workbench 2.

[0026] In use, by pulling the handle 45 forward with both hands, the frame 41 moves forward within the sliding groove 3. As the frame 41 moves forward, the guide rod 42 also moves forward, thereby squeezing the reset spring 44 located between the rear side wall of the worktable 2 and the limiting plate 43. The guide table 46 slides forward along the sliding groove 3, pushing the cleaning brush 47 to sweep the chips on the top surface of the worktable 2 forward. When the guide table 46 reaches the front end of the sliding groove 3, the chips will fall into the chip discharge port 6. After releasing the handle 45, the elasticity of the reset spring 44 will cause the limiting plate 43 to push the frame 41 and the guide rod 42 back to their original positions, further ensuring quick and convenient operation and effectively reducing the difficulty of operation.

[0027] Preferably, the size of the frame 41 is adapted to the size of the sliding groove 3, and the length of the guide rod 42 is set to correspond to the width between the front and rear of the worktable 2, ensuring that the frame 41 can move smoothly in the sliding groove 3 without shaking or jamming; the length of the guide rod 42 allows the limiting plate 43 to move flexibly within the width range of the worktable 2, ensuring that the cleaning brush 47 can cover the entire surface of the worktable 2, achieving comprehensive cleaning, improving cleaning efficiency, and ensuring stability and durability.

[0028] Preferably, the two guide rods 42 are arranged symmetrically on the rear side of the frame 41, which enhances the stability of the frame 41 and allows the guide rods 42 to distribute the force evenly when subjected to force, thus avoiding equipment damage or operation disruption caused by uneven force.

[0029] Preferably, the front side of the machine body 1 has a placement groove 7, which communicates with the chip discharge port 6. A chip collection drawer 8 is slidably engaged inside the placement groove 7. A guide plate 9 corresponding to the chip discharge port 6 is fixedly installed on the front side of the workbench 2. The guide plate 9 guides the chips to the chip discharge port 6, effectively preventing chips from scattering in the work area and maintaining a clean working environment. The sliding engagement of the chip collection drawer 8 makes it easy for users to pull it out for cleaning at any time, making the operation simple and quick, further improving the practicality and convenience of the equipment.

[0030] Please see Figure 2 and Figure 5 In some embodiments, the shielding component 5 includes a left baffle 51 and a right baffle 52 symmetrically arranged. The left baffle 51 and the right baffle 52 are slidably arranged on the left and right sides of the top outer side of the workbench 2, respectively. Both the left baffle 51 and the right baffle 52 are U-shaped structures. The bottom of the outer side of the left baffle 51 and the right baffle 52 are fixedly installed with symmetrically arranged limiting rods 53. Two guide holes 21 are opened on the inner walls of the left and right sides of the top of the workbench 2. The limiting rods 53 slide through the corresponding guide holes 21. Two guide grooves 54 are opened on the top of the machine body 1 symmetrically arranged. Support rods 55 are fixedly installed on the bottom of the sides of the left baffle 51 and the right baffle 52 that are far apart from each other. Rollers 56 located in the guide grooves 54 are movably installed on the bottom of the support rods 55.

[0031] In use, by pushing the left stop frame 51 and the right stop frame 52 inward, the limiting rod 53 slides in the guide hole 21 and guides the roller 56 at the bottom of the support rod 55 to roll in the guide groove 54. When the left stop frame 51 and the right stop frame 52 approach each other and engage with each other, they can block the side of the workbench 2. While ensuring simple and convenient operation, they can improve the protection effect and effectively reduce the splashing of chips, thereby simplifying the subsequent cleaning work.

[0032] Preferably, the ends of the left and right retaining frames 51 and 52 that are close to each other are provided with matching engaging grooves 57. The engaging grooves 57 allow the left and right retaining frames 51 and 52 to engage tightly when they are close to each other, enhancing the stability and sealing effect of the shielding assembly 5. When the engaging grooves 57 of the left and right retaining frames 51 and 52 are fully aligned and locked, it effectively prevents chips generated during the cutting process from splashing onto other areas of the worktable 2, improving the cleanliness of the working environment.

[0033] Preferably, handles are fixedly installed on the middle of the sides of the left and right baffle frames 51 and 52, which are far apart from each other. The handles allow the operator to manually push and pull the left and right baffle frames 51 and 52 to make them slide. By holding the handles and applying appropriate force, the operator can easily bring the left and right baffle frames 51 and 52 closer together and engage them, thereby quickly achieving the blocking and separation of the sides of the workbench 2. This improves the convenience of operation, ensures that the blocking component 5 can be quickly and accurately positioned, and further enhances the efficiency and practicality of the entire chip cleaning device.

[0034] Working principle: When the differential housing is placed on the workbench 2 and processed by the machine body 1, the left and right retaining frames 51 and 52 are pushed inward, causing the left and right retaining frames 51 and 52 to drive the limiting rod 53 to slide in the guide hole 21. This causes the roller 56 at the bottom of the support rod 55 to roll inward in the guide groove 54. As the left and right retaining frames 51 and 52 approach each other, the engaging grooves 57 at their approaching ends engage together, thereby providing multi-directional shielding for the side of the workbench 2. This improves the protective effect and effectively reduces chip splashing, preventing chips from falling onto the workbench 2 and improving the ease of subsequent cleaning.

[0035] After machining the differential housing, slide the left retaining frame 51 and right retaining frame 52 outward to remove the workpiece. Then, pull the handles 45 on both sides of the frame 41 forward with both hands. The handles 45 drive the frame 41 to slide forward in the sliding groove 3. The frame 41 drives the guide rod 42 to move forward, which in turn squeezes the return spring 44 located between the rear side wall of the worktable 2 and the limiting plate 43. The guide table 46 slides forward in the sliding groove 3, driving the cleaning brush 47 to sweep the chips on the worktable 2 forward. When the guide table 46 moves to the front of the sliding groove 3, the chips are guided from the front of the sliding groove 3 through the guide plate 9 and fall into the chip discharge port 6. The chip discharge port 6 connects to the placement groove 7, allowing the chips to fall into the chip collection drawer 8 for collection. After releasing the handles 45, the elastic force of the return spring 44 pushes the limiting plate 43, causing the frame 41 and guide rod 42 to move backward and reset. The operation is quick and convenient, further reducing the difficulty of operation. The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0036] 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.
