Technical Field

[0001] The present application relates to the field of machine tools, and in particular to a slide movable guide rail protection device. Background Art

[0002] The C-type slide is fixedly connected to the bed through a locking cylinder, but when the C-type slide needs to move on the surface of the bed, the huge contact area between the C-type slide and the bed will cause the C-type slide to shake and crawl during movement.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-6 This application is described in further detail.

[0031] The present application embodiment discloses a slide 2 movable guide rail protection device, which is generally used in a broaching machine (a type of machine tool), including a bed 1 and a slide 2, wherein the slide 2 is located above the bed 1 and can move relative to the bed 1 and contact the bed 1 and is locked by a locking device after the slide 2 stops moving. The specific structure of the slide 2 is a C-shaped slide 2, and of course it can also be other structures such as a V-shaped slide.

[0032] Since the huge contact area between the C-type slide 2 and the bed 1 will cause the C-type slide 2 to shake and crawl during movement, a linear guide is set between the bed 1 and the slide 2. Specifically, the linear guide is composed of a slide rail 3 and a slider 4. An empty groove 5 is provided on the upper surface of the bed 1 and / or the lower surface of the slide 2 so that the upper surface of the bed 1 and the lower surface of the slide 2 are partially in contact. The contacting portion of the upper surface of the bed 1 and the lower surface of the slide 2 is the contact area, and the rest is the non-contact area; the area of ​​the contact area is close to that of the non-contact area, and the slide rail 3 and the slider 4 are located in the contact area. The slide rail 3 is fixed to the bed 1 by bolts, and the slider 4 is slidably set on the slide rail 3.

[0033] The locking device is a locking cylinder 6 and is arranged perpendicular to the contact surface of the bed 1 and the slide 2. A locking head 61 is connected to the piston rod of the locking cylinder 6. The locking head 61 is a T-shaped structure. A locking groove 21 for accommodating the locking head 61 is provided on the slide 2. At least one end of the locking groove 21 passes through the side wall of the slide 2. The cylinder body of the locking cylinder 6 is fixed on the bed 1.

[0034] The slide 2 is provided with an active cavity 22, and the slide rail 3 and the slider 4 are both located in the active cavity 22. The bed 1 is provided with a cavity 23 for accommodating an elastic limiter, and the cross section of the cavity 23 is smaller than the cross section of the active cavity 22. The cavity 23 is connected to the active cavity 22, and an elastic support member is also provided in the cavity 23. The elastic support member is located between the slider 4 and the slide 2 and lifts the slide 2 when the locking device is unlocked so that a gap is set between the slide 2 and the bed 1. The elastic support member can directly or indirectly abut against the slider 4 and the inner wall of the cavity 23, and the extension direction of the elastic support member is perpendicular to the contact surface of the slide 2 and the slide rail 3. Since the bed 1 is generally placed horizontally, the extension direction of the elastic support member can also be simply understood as extension in the vertical direction.

[0035] In this solution, the elastic support member is preferably a disc spring 7, which is usually made of standard material CK67. For special needs, the highest-grade spring material 50CrV4 can also be selected, which can maintain good spring characteristics at a working temperature of -15°C to 150°C. In terms of surface treatment, phosphoric acid treatment and lubricating oil can be selected, or electroplating treatment such as galvanizing, steel, chrome, metal film, and baking varnish can be performed as needed.

[0036] In order to prevent the disc spring 7 from shifting during the deformation process (shift refers to deviation from its set extension and retraction direction), a guide member is provided, and an installation cavity 24 for installing the guide member is provided on the slide 2. The guide member is at least partially inserted into the elastic support member so that the elastic support member is compressed or reset in the direction perpendicular to the contact surface between the slide 2 and the bed 1. A mounting hole 25 is provided on the bed 1, and the mounting hole 25 is connected to the cavity 23 and the mounting cavity 24, and the guide member partially passes through the mounting hole 25. Preferably, the guide member includes a locking rod 8, and the locking rod 8 can be directly fixed to the slide 2 by welding. In this solution, for the convenience of installation, it is indirectly fixed to the slide 2 by a locking nut 9. Specifically, the locking nut 9 is fixed to the slide 2 by welding, and the locking rod 8 passes through the locking nut 9 and is threadedly connected to the locking nut 9 and passes through the mounting hole 25 to extend into the cavity 23.

[0037] In this solution, the elastic reset member is indirectly abutted against the slide 2. The specific guide member has a limit surface 83, and the limit surface 83 abuts against the elastic support member. When the guide member takes the above-mentioned locking rod 8 as an example, the locking rod 8 includes a guide portion 81 and a connecting portion 82. The diameter of the guide portion 81 is smaller than the diameter of the connecting portion 82, so that a limit surface 83 is formed at the junction of the connecting portion 82 and the guide portion 81. The elastic support member is a disc spring 7, and at least two disc springs 7 are stacked. The disc springs 7 are stacked by the alignment method (the disc spring 7 is a truncated cone / conical disc-shaped structure. The alignment method stacking means that the end face of the disc spring 7 with a small cross-section abuts against the end face of the disc spring 7 with a small cross-section, and the end face with a large cross-section abuts against the end face with a large cross-section). Three disc springs 7 are arranged, two of which are sleeved on the guide portion 81, and the inner diameter of the disc spring 7 is slightly larger than the diameter of the guide portion 81 (which can be understood as a clearance fit). The remaining disc spring 7 is located on the transition piece 10. The transition piece 10 is in the shape of a plate. The transition piece 10 is formed with a receiving portion 101 for the elastic support member. The receiving portion 101 is a circular groove structure. The transition piece 10 is fixed to the slider 4 by bolts. The transition piece 10 can be understood as a part of the slider 4 (the main function of the transition piece 10 is that the conventional slider 4 does not have a receiving portion 101, so as to set the receiving portion 101). When the locking device is unlocked, the guide portion 81 does not extend into the disc spring 7 located in the receiving portion 101.

[0038] The implementation principle of the slide 2 movable guide rail protection device of the embodiment of the present application is as follows: when the locking cylinder 6 is unlocked, the disc spring 7 is compressed, and a gap is set between the slide 2 and the bed 1 under the support of the disc spring 7, and the slide 2 can be moved by the slider 4; when the locking cylinder 6 is working, the slide 2 and the bed 1 will be fitted together, and at this time, the locking rod 8 moves vertically downward with the C-shaped cradle and squeezes the disc spring 7 to deform it. At this time, the disc spring will absorb part of the pressure applied to the slider 4, thereby protecting the slider 4 from damage.
