Description

Technical Field

[0001] The utility model relates to the technical field of protective covers, in particular to a novel guide rail protective cover. Background Art

[0002] The guide rail protective cover is a protective device that moves along the internal guide rail of a CNC machine tool. The guide rail protective cover is arranged on the outside of the rail, so as to effectively prevent the turning debris from falling onto the rail and affecting the normal operation of the equipment. The existing protective cover will install an end plate at its end, and guide rollers, anti-collision pads, etc. are arranged on the end plate. The end plate and the protective cover are generally fixed by welding or pins during installation. Among them, welding fixation is easy to cause deformation of the protective cover due to heat generated during processing, and the pins are directly arranged at the end of the protective cover, and pin holes are arranged on the end plate at the position corresponding to each pin. After the pin is inserted into the pin hole, the staff needs to use a tool to hammer the pin, so that the pin is deformed and bent. The bent pin is directly clamped on the end plate, so as to fix the end plate and the protective cover. Although this connection method can avoid thermal deformation, in order to make the end plate have a stable connection, multiple pins need to be set, so that the staff needs to hammer each pin, which greatly increases the workload of the staff and brings great inconvenience to the processing work.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0020] like Figure 1-4 As shown, a novel guide rail protective cover described in this embodiment includes a protective cover body 1 that is sequentially plugged in and can be pulled out, and the protective cover body 1 is provided with a mounting edge 11 at one end thereof, and an end plate 3 is installed at the mounting edge 11 through a quick-install lock pin 2, and the end plate 3 is provided with guide mechanisms 4 that are arranged to fit the guide rail on both symmetrical sides thereof;

[0021] The quick-install locking pin 2 includes a pin rod 21 that passes through the mounting edge 11 and the end plate 3 at the same time, a stop cap 22 that is fitted with the mounting edge 11 is provided at one end of the pin rod 21, and a protruding head 23 that extends outward from the end plate 3 is provided at the other end of the pin rod 21, and the diameter of the protruding head 23 is smaller than the diameter of the pin rod 21, and a retaining ring 24 is sleeved on the protruding head 23, the outer diameter of the retaining ring 24 is the same as the diameter of the pin rod 21 and the inner diameter thereof is larger than the diameter of the protruding head 23, and a locking cap 25 for clamping and fixing the retaining ring 24 is provided at the end of the protruding head 23, and an anti-collision pad 26 is provided at the end of the locking cap 25. The anti-collision pad 26 is assembled together with the quick-install locking pin 2, which can save the step of installing a traditional gasket and greatly improve the assembly efficiency of the protective cover.

[0022] A threaded rod 27 is provided at one end of the locking cap 25 connected to the raised head 23, and a threaded hole matching the threaded rod 27 is provided at the end of the raised head 23. The locking cap 25 is threadedly connected to the raised head 23. By tightening the locking cap 25 at the end of the raised head 23, the retaining ring 24 can be clamped at the raised head 23, so that the retaining ring 24 cannot move.

[0023] The mounting edge 11 is provided with a plurality of first mounting holes along its circumference, and the end plate 3 is provided with a plurality of second mounting holes corresponding to the positions of the first mounting holes, and the quick-installation locking pin 2 passes through the two mounting holes at the same time.

[0024] An internal thread is provided in the first mounting hole, and an external thread is provided on the pin rod 21 near the stop cap 22. The pin rod 21 is threadedly connected to the first mounting hole. During installation, the pin rod 21 can be pre-screwed to the mounting edge 11. During subsequent assembly, it is only necessary to connect the end plate 3 to the protective cover body 1.

[0025] Preferably, the material of the anti-collision pad 26 is rubber.

[0026] The guide mechanism 4 comprises a mounting frame 41 arranged on the end plate 3 , and a long guide roller 42 and a short guide roller 43 are arranged on the mounting frame 41 .

[0027] The long guide roller 42 is horizontally placed on the mounting frame 41 through an axle rod, and the short guide roller 43 is vertically placed on the mounting frame 41 through an axle rod.

[0028] Preferably, the material of the protective cover body 1 and the end plate 3 is stainless steel.

[0029] When installing the utility model, first install the quick-install lock pin 2 on the installation edge 11 of the protective cover body 1, then dock the end plate 3 with the end of the protective cover body 1, and the pin rod 21 of the quick-install lock pin 2 passes through the second installation hole on the end plate 3. When the end plate 3 abuts against the installation edge 11 of the protective cover body 1, the retaining ring 24, the lock cap 25 and the anti-collision pad 26 at the end of the pin rod 21 just extend out of the front side of the end plate 3. At this time, the lock cap 25 is loosened, and the retaining ring 24 can move at the protruding head 23, and one side of the retaining ring 24 is controlled to extend outward from the pin rod 21.
