Description

TECHNICAL FIELD

[0001] The utility model relates to the field of machining, especially a horizontal machining center door type linkage helmet formula telescopic protective cover. BACKGROUND

[0002] Because the horizontal machining center or high pressure deburring cleaning machine type machine tool has higher protection requirement, and the equipment runs fast. In the machining process, the cutting chip and cutting chip liquid can splash on the key precision components in the spindle or machine tool interior, which not only affects the service life and normal work of the machine tool, but also is inconvenient to clean the cutting chip. Therefore, the spindle and screw rod guide rail and other key precision components of the machine tool need to be protected. A horizontal machining center movement roller shutter telescopic protective cover is disclosed in Chinese patent document, and the authorization publication number is CN215967745U. The protective roller shutter of the movement roller shutter telescopic protective cover is easy to be abraded by the cutting chip attached to the roller shutter during the extension process, which reduces the service life of the roller shutter. SUMMARY

[0003] In view of the above technical problems of the prior art, the utility model solves the technical problems: how to provide a structure design reasonable, stable and fast moving, corrosion resistant, can effectively protect the spindle and screw rod guide rail and other key precision components of the machine tool, and convenient to clean the cutting chip, prolong the service life of the protective cover.

[0004] In order to solve the above technical problems, the utility model adopts the following technical scheme:

[0005] A horizontal machining center door type linkage helmet formula telescopic protective cover, comprising an outer frame, an inner frame and a center spindle connecting frame which are in the shape of a rectangle as a whole, the inner frame is transversely slidably arranged in the outer frame, the center spindle connecting frame is vertically slidably arranged in the inner frame, and the center spindle connecting frame has a mounting hole for connecting the spindle of the machine tool in the middle part; the outer frame has a transversely arranged guide beam near the top, the upper end of the inner frame is rotatably hung on the guide beam through a rolling part; the two sides of the inner frame in the transverse direction are provided with a telescopic first organ type protective cover between the outer frame, and the two sides of the center spindle connecting frame in the vertical direction are provided with a telescopic second organ type protective cover between the inner frame; the outer side of the first organ type protective cover and the second organ type protective cover is covered with a helmet telescopic sheet which is stacked and connected in the telescopic direction.

[0006] Using the above structure, the inner frame is installed inside the outer frame, and the central spindle connecting frame is vertically slidably installed inside the inner frame. When the spindle passes through the outer frame and moves vertically during machining, the central spindle connecting frame moves vertically along the inner frame under the drive of the spindle. The second accordion-style protective cover located on the inner frame moves or retracts relative to the central spindle connecting frame. When the spindle moves horizontally during machining, the central spindle connecting frame and the inner frame move together, causing the first accordion-style protective cover to retract or retract. When the first and second accordion-style protective covers retract or retract, the armor-like telescopic plates covering the outer side move with the first and second accordion-style protective covers. When the protective cover retracts, the overlapping connection area between two adjacent armor-like telescopic plates gradually decreases. By utilizing the retractable first and second accordion-style protective covers, movement between the inner frame, protective plate, and outer frame can be achieved, thus realizing the free movement of the spindle. Meanwhile, the stacked, interconnected telescopic armor plates can block chips generated during spindle machining and accumulate them, thus protecting the spindle and facilitating chip removal. This extends the service life of the telescopic protective cover. Furthermore, the inner frame is rotatably mounted on the guide beam of the outer frame via rolling components, reducing friction between the inner frame and the guide beam, allowing for smoother horizontal movement of the inner frame and meeting the demands of high-speed movement.

[0007] Preferably, both the first and second accordion-style protective covers include multiple PVC support plates arranged parallel to each other along the telescopic direction. A pull strap with a "V"-shaped indentation in the middle is connected between two adjacent PVC support plates. The two sides of the pull strap can be unfolded or closed along the middle crease. On the first accordion-style protective cover, the pull strap extends along the length direction of the PVC support plate and two sets are arranged facing each other along the thickness direction of the first accordion-style protective cover.

[0008] In this way, the PVC support plate of the first accordion-style protective cover can be moved horizontally and pulled up, which is not easy to cause deformation due to front and back pulling and helps to extend the service life of the protective cover.

[0009] Furthermore, the armor telescopic plates are elongated and evenly distributed along their width on the corresponding first or second accordion-style protective cover; one side of the armor telescopic plate in the width direction is fixedly connected to the PVC support plate, and the other side overlaps the surface of the adjacent armor telescopic plate; the middle of the armor telescopic plate has a crease that runs through it along its length, and both sides of the armor telescopic plate in the width direction are bent towards the protective side along the crease, so that the side of the armor telescopic plate overlaps the surface of another armor telescopic plate; the maximum distance between the PVC support plates where two adjacent armor telescopic plates are located is less than the width of the armor telescopic plate.

[0010] The mutually connected armor stretchable pieces can move relative to the surface of another armor stretchable piece on the connected side when moving, and form scraping on the surface, gather small volume or light weight cuttings, facilitate centralized cleaning, and reduce cleaning difficulty.

[0011] Preferably, the inner side of the inner frame is provided with two guide grooves arranged opposite in the transverse direction and extending in the vertical direction, the two sides of the central spindle connecting frame are provided with rollers corresponding to the guide grooves and slidably matched in the guide grooves, and the inner side of the inner frame is provided with guide plates arranged in the vertical direction and located on the two sides of the second accordion shield.

[0012] Further, the outer frame is provided with a guide beam arranged in the transverse direction near the top, the guide hole is in the shape of a rectangle as a whole and is provided with an assembly slot penetrating from the lower end towards the direction away from the armor stretchable piece, the width of the assembly slot is greater than the longitudinal width of the guide beam, the upper end of the guide hole is provided with a sliding block in the shape of L as a whole, the sliding block is slidably hung on the guide beam, and the upper end of the inner frame is provided with a cross beam arranged in parallel with the guide beam.

[0013] In this way, the inner frame and the first accordion shield can slide along the surface of the guide beam, so that the guiding structure is more stable, the sliding block arranged on the guide hole can be in movable contact with the guide beam, the friction area is reduced, and the movement of the spindle is facilitated.

[0014] In summary, the utility model has the advantages of reasonable structure design, convenient movement, effective protection of the spindle, easy cleaning of the cuttings, and prolonged service life of the shield. BRIEF DESCRIPTION OF DRAWINGS
