[0022] The utility model is described in further detail below:

[0023] like Figures 1 to 5As shown, the utility model provides a grinding device for wrench processing, including a base 1 and a stand 2 fixedly connected to the top of the base 1, a protective cover 3 and a fixing component 5 are fixedly installed on the top of the stand 2, the fixing component 5 is arranged on the left side of the protective cover 3, the left side opening of the protective cover 3 is arranged, a grinding component 4 is movably installed on the top of the protective cover 3, a dust removal component 6 is fixedly installed on the top of the base 1, the fixing component 5 includes a slide rail 51, the outer part of the slide rail 51 is movably clamped with a slider 52, the top of the slider 52 is fixedly connected to a fixing frame 53, the top of the fixing frame 53 is provided with a placement slot 54, a threaded rod 55 is rotatably installed on the front and back of the top of the fixing frame 53, the top of the threaded rod 55 is fixedly connected to a handwheel 56, the outer part of the threaded rod 55 is threadedly connected to a movable frame 57, and the bottom of the movable frame 57 is fixedly connected to a pressure block 58 corresponding to the placement slot 54.

[0024] The wrench is clamped inside the placement groove 54, and the threaded rod 55 is rotated synchronously by synchronously rotating the hand wheel 56, thereby driving the movable frame 57 to drive the pressure block 58 to move downward, and the pressure block 58 at the bottom of the movable frame 57 is extended into the placement groove 54 to press and fix the wrench, so as to facilitate the fixation of multiple wrenches at one time, and by sending the fixing frame 53 into the interior of the protective cover 3 to cooperate with the grinding assembly 4 to perform simultaneous grinding operations on multiple wrenches in batches, thereby reducing the labor intensity and improving the grinding efficiency.

[0025] like Figure 4 As shown, the grinding assembly 4 includes a telescopic electric cylinder 41, which is fixedly mounted on the top of the protective cover 3, and a mounting frame 42 located inside the protective cover 3 is fixedly mounted on the bottom of the telescopic electric cylinder 41, a fixed roller 43 is movably mounted inside the mounting frame 42, a grinding belt 44 is movably mounted outside the fixed roller 43, and a driving motor 45 connected to the fixed roller 43 is fixedly mounted on the outside of the mounting frame 42.

[0026] The driving motor 45 can drive the fixed roller 43 to rotate and then drive the grinding belt 44 to grind the contacted wrenches. Multiple wrenches can be ground at the same time, and the grinding accuracy can be controlled by controlling the mounting frame 42.

[0027] like Figure 3 and Figure 5 As shown, the dust removal component 6 includes a recovery cover 61 and a collection box 62. The recovery cover 61 is fixedly installed inside the stand 2, and the collection box 62 is fixedly installed on the top of the base 1. The collection box 62 is connected to the recovery cover 61. The outside of the collection box 62 is connected to an exhaust fan 63. The inside of the collection box 62 is movably connected to a collection frame 64. A ventilation duct 66 is fixedly installed on the left side of the inside of the protective cover 3, and a blowing branch pipe 67 is fixedly connected to the bottom of the ventilation duct 66. An air blower 68 connected to the ventilation duct 66 is fixedly installed on the back side of the protective cover 3.

[0028] By turning on the vacuum pump 63 and the blower 68, external air is sucked into the ventilation duct 66 through the blower 68 and air is blown from the blowing branch 67 which is inclined toward the grinding assembly 4, and the waste chips generated by grinding are blown to the side of the protective cover 3 away from the opening, and the waste chips fall into the recovery cover 61. The suction force generated by the vacuum pump 63 sucks the waste chips from the recovery cover 61 into the collection box 62, which is filtered and collected in the collection frame 64. In conjunction with the protective cover 3, the scattering of grinding waste chips can be reduced, and the stable collection of waste chips can be ensured.

[0029] like Figure 2 As shown, the placement slots 54 are longitudinally and equidistantly opened on the top of the fixing frame 53 .

[0030] Multiple wrenches can be fixed synchronously by the placement slots 54 arranged at equal intervals, thereby facilitating simultaneous grinding, improving efficiency and reducing manual labor intensity.

[0031] like Figure 2 As shown, a second threaded rod 59 is movably installed on the inner side of the slide rail 51 , a second hand wheel 510 is fixedly connected to the outer side of the second threaded rod 59 , and the fixing frame 53 is threadedly connected to the outer side of the second threaded rod 59 .

[0032] By cooperating with the setting of the second threaded rod 59 and the second hand wheel 510, the fixing frame 53 can be driven to slide by the rotation of the second threaded rod 59, thereby facilitating the adjustment of the distance that the wrench extends into the interior of the protective cover 3, and facilitating the insertion of the wrench into the protective cover 3 for grinding and pulling it out for placement.

[0033] like Figure 3 and Figure 5 As shown, the recovery cover 61 is located directly below the protective cover 3 , and the size of the recovery cover 61 is adapted to the protective cover 3 .

[0034] Because the recovery cover 61 is located directly below the protective cover 3 , the waste chips can be completely dropped into the recovery cover 61 by blowing downwards through the blowing branch pipe 67 , thereby facilitating the collection of the waste chips.

[0035] like Figure 3 As shown, the blowing branch pipe 67 is arranged obliquely toward the bottom of the grinding assembly 4.

[0036] By tilting the blowing branch pipe 67 downward toward the grinding assembly 4 , oblique blowing can be ensured to prevent waste chips from being discharged from the side opening of the protective cover 3 , thereby ensuring stable collection of waste chips and reducing dust dispersion.

[0037] like Figure 5 As shown, a box cover 65 is movably installed on the front side of the collection box 62.

[0038] The box cover 65 is hingedly mounted on the front side of the collection box 62 and can be closed and clamped, so that it is convenient to open and remove the collection frame 64 for cleaning.

[0039] The working principle of the grinding device for wrench processing will be described in detail below.

[0040] like Figures 1 to 5 As shown, by placing the wrench card inside the placement groove 54 and synchronously rotating the handwheel 1 56 located above the fixed frame 53, the handwheel 1 56 drives the threaded rod 1 55 to rotate synchronously, thereby driving the movable frame 57 to drive the pressure block 58 to move downward, and the pressure block 58 at the bottom of the movable frame 57 is extended into the placement groove 54 to press and fix the wrench, and then the handwheel 2 510 is rotated to drive the threaded rod 2 59 located on the inner side of the slide rail 51 to rotate, and the rotation of the threaded rod 2 59 drives the fixed frame 53 to drive the slider 52 to move into the protective cover 3 with the left opening, and the wrench is extended into the interior of the protective cover 3 and adjusted its position, and then the installation is driven by controlling the telescopic electric cylinder 41. The frame 42 descends to make the grinding belt 44 contact the surface of the wrench, and the fixed roller 43 is driven to rotate by the driving motor 45, thereby driving the grinding belt 44 to grind the wrench. During grinding, the vacuum pump 63 and the blower 68 are turned on, and the external air is sucked into the ventilation duct 66 by the blower 68 and blown from the blowing branch 67 inclined toward the grinding component 4, so that the waste chips generated by grinding are blown to the side of the protective cover 3 away from the opening, and the waste chips fall into the recovery cover 61. The suction force generated by the vacuum pump 63 sucks the waste chips from the recovery cover 61 into the collection box 62 and is filtered through the filter screen set on the side of the vacuum pump 63 and falls into the collection frame 64 for collection.

[0041] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
