[0028] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail below.

[0029] A lockable machine tool slide rail accessory, see reference. Figure 1-7 It includes a slide rail 1, a slider 2, a brake strip 3 and a brake assembly 4. The slider 2 is fitted on the outside of the slide rail 1 and the slider 2 is slidably connected to the slide rail 1. The bottom of the front and rear sides of the slide rail 1 is provided with mounting grooves 11 and the brake strip 3 is installed in the mounting grooves 11. The bottom of the front and rear sides of the slider 2 is provided with brake assemblies 4 and the two sets of brake assemblies 4 are arranged symmetrically in front and behind.

[0030] The braking assembly 4 includes a housing 41, a movable plate 42, a limiting rod 43, a spring 44, a magnetic plate 45, an electromagnet 46, a braking block 47, and a connecting piece 48. The movable plate 42 is horizontally arranged inside the housing 41. The limiting rod 43 penetrates the interior of the movable plate 42, and both ends of the limiting rod 43 are fixedly connected to the housing 41. The rear side of the movable plate 42 is elastically connected to the housing 41 through the spring 44, and the spring 44 is fitted onto the outside of the limiting rod 43. The magnetic plate 45 is fixedly fixed to the middle of the rear end of the movable plate 42. The electromagnet 46 is fixedly fixed to the rear side of the interior of the housing 41. The braking blocks 47 are fixedly connected to the left and right sides of the rear end of the movable plate 42. The outer side of the housing 41 is fixedly connected to the connecting piece 48, and the connecting piece 48 is fixedly connected to the slider 2.

[0031] Brake bar 3 is arranged parallel to slide rail 1, and anti-slip texture is provided on the outer side of brake bar 3; brake bar 3 is made of GCr15 bearing steel, and is quenched and tempered at low temperature, and its surface hardness is not less than HRC60; brake block 47 is made of copper-based powder metallurgy material sintered, and graphite lubricating phase is uniformly distributed in the matrix. In order to further improve its wear resistance, a wear-resistant coating is provided on the working surface of brake block 47 near brake bar 3. The wear-resistant coating is a hard chrome coating with a thickness of 50μm and its microhardness is not less than HV800.

[0032] A protrusion 31 is provided on the side of the brake bar 3 near the slide rail 1, and a groove that fits the protrusion 31 is provided in the mounting groove 11 of the slide rail 1. When the brake block 47 presses the brake bar 3 to lock the slide rail, a huge frictional force is generated. This frictional force will try to make the brake bar 3 move or slip along the direction parallel to the slide rail (i.e., the direction of shear force). The protrusion 31 is embedded in the groove, and most of the shear force is directly borne by the side of the groove, which significantly improves the stability and reliability of the locking state.

[0033] Limiting grooves 12 are provided on the top of both the front and rear sides of the slide rail 1, and sliding blocks 21 that fit into the limiting grooves 12 are provided on both the front and rear sides of the slider 2. The sliding blocks 21 are slidably connected to the limiting grooves 12, so that when the slider 2 slides along the length of the slide rail 1, the sliding blocks 21 slide along the limiting grooves 12 of the slide rail 1.

[0034] The movable plate 42 and the brake block 47 are arranged parallel to the brake strip 3, so that when the slider 2 slides, the brake block 47 and the brake strip 3 move relatively parallel to each other, thus avoiding the problem of the brake block 47 automatically contacting the brake strip 3.

[0035] The limiting rod 43 penetrates vertically through the movable plate 42, and the inner wall of the movable plate 42 is in contact with the limiting rod 43. At least two limiting rods 43 are provided to restrict the movement of the movable plate 42.

[0036] The rear left and right sides of the outer shell 41 are provided with through holes that fit with the brake block 47, and the rear end of the brake block 47 extends through the through holes on the rear side of the outer shell 41, which increases the smoothness of the movement of the brake block 47. After the brake block 47 fits with the brake strip 3, the brake block 47 brakes the outer shell 41, and then brakes the slider 2.

[0037] The lockable machine tool slide rail accessory of this utility model mainly achieves rapid locking and releasing of the slider through electromagnetic control. Its working principle is as follows:

[0038] When it is necessary to lock the position of slider 2, electromagnet 46 is energized, generating a magnetic field opposite to that of magnetic plate 45, attracting magnetic plate 45 to move, driving movable plate 42 to compress spring 44, causing brake block 47 to press brake strip 3. Brake strip 3 has anti-slip texture on its surface, and brake block 47 has a hard chrome wear-resistant layer plated on its contact surface. The two generate a large friction force, thereby achieving reliable braking of slider 2.

[0039] When it is necessary to move slider 2, the power supply to electromagnet 46 is cut off, the magnetic field disappears, spring 44 returns to its deformation, pushes movable plate 42 to move outward, so that brake block 47 disengages from brake bar 3, and slider 2 can slide freely along slide rail 1.

[0040] The brake strip 3 is installed by the engagement of the protrusion 31 with the groove of the mounting slot 11, which can effectively resist the shearing force generated during braking and prevent the brake strip 3 from shifting.

[0041] In summary, this accessory achieves rapid response locking through electromagnetic control combined with mechanical spring reset, and features a compact structure, simple operation, and high reliability.

[0042] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0043] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
