Description

Technical Field

[0001] The utility model relates to the technical field of metal plate grinding jigs, in particular to a metal plate grinding jig. Background Art

[0002] The metal plate grinding jig is a tool specially used for grinding metal plates. When the metal plate is being ground, the jig is used to fix the metal plate to ensure the stability of the metal plate grinding process.

[0003] However, some grinding jigs can only fix, feed and unload metal plates one by one during fixed grinding of metal plates, which is not conducive to continuous grinding of metal plates and reduces the efficiency of metal plate grinding. In addition, for metal plates that need double-sided grinding, it is not conducive to turning the materials in a fixed state and manual assistance is required for adjustment, which increases the operation process of metal plate grinding and increases its operation complexity.

[0004] Therefore, we proposed a metal plate grinding jig to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to provide a metal plate grinding jig to solve the problems in the current market raised by the above-mentioned background technology that the metal plates are not conducive to continuous grinding processing, are not conducive to turning the metal plates in a fixed state, and are not convenient for double-sided grinding of the metal plates.

[0006] To achieve the above object, the utility model provides the following technical solution: a metal plate grinding jig, comprising a jig main frame, a motor is installed inside the jig main frame, an output end of the motor is connected to a connecting frame, a mounting ring is installed at the lower end of the connecting frame, and a limiting ring is connected to the inner side of the mounting ring;

[0007] The outer side of the mounting ring is rotatably connected with a rotating shaft, the end of the rotating shaft is installed with a supporting seat, the end of the supporting seat is sleeved with a limiting seat, the limiting seat is elastically connected to the supporting seat through a first spring, the outer side of the rotating shaft is keyed with a gear, and a positioning hole is opened on the outer side of the rotating shaft;

[0008] The outer side surface of the mounting ring is connected with a fixing plate, the end of the fixing plate is elastically connected with a positioning rod via a second spring, the end of the positioning rod is installed with a first magnet, and the positioning rod and the positioning hole are engaged with each other.

[0009] Preferably, a hydraulic rod is installed on the outer side of the upper end of the jig main frame, the output end of the hydraulic rod is connected to an adjustment frame, and a gear block and a second magnet are installed on the outer side of the adjustment frame.

[0010] Preferably, there is a gap between the connecting frame, the hydraulic rod and the adjusting frame, and the lowest point of the adjusting frame in the initial position is higher than the highest point of the fixed plate. This design can avoid mutual obstruction between the connecting frame, the hydraulic rod and the adjusting frame when the mounting ring is driven to rotate, and at the same time avoid the adjusting frame obstructing the fixed plate from following the movement of the mounting ring.

[0011] Preferably, the mounting ring forms a rotating structure with the fixture main frame through a limiting ring, and support seats are distributed at equal angles on the outside of the mounting ring. This design can use the limiting ring to support the mounting ring, ensure the stable rotation of the mounting ring, and adjust the work station formed by the support seat.

[0012] Preferably, the end of the support seat that passes through the limit seat is an "I"-shaped structure, the limit seat and the support seat are slidably connected, and the limit seat and the support seat are fixed by bolts. This design can prevent the limit seat from detaching from the support seat, ensure the stable movement of the limit seat, and fix the metal plate.

[0013] Preferably, the position of the first magnet and the position of the second magnet are set correspondingly, and the first magnet and the second magnet are magnets of opposite poles. This design can use the attraction between the magnets to adjust the position of the positioning rod, and the positioning rod can be moved out of the positioning hole to release the lock on the rotating shaft.

[0014] Preferably, the tooth blocks are evenly spaced at the connection between the adjustment frame and the gear, and the gear and the support seat are coaxially connected. This design can utilize the movement of the adjustment frame to drive the gear to rotate, thereby controlling the synchronous rotation of the support seat to flip the locked metal plate.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] (1) The metal plate grinding fixture can limit the metal plate according to the size of the metal plate by driving the limit seat to move, and the multiple stations can be set to feed the metal plate by driving the rotating ring. While the metal plate is being ground at the grinding station, the staff can load and unload the metal plate synchronously, thereby improving the processing speed and sustainably grinding the metal plate.

[0017] (2) The metal plate grinding fixture controls the hydraulic rod to drive the adjustment frame to move. First, the attraction of the first magnet and the second magnet with different polarities is used to move the positioning rod out of the positioning hole to release the limit on the rotating shaft. Then, the transmission of the meshing tooth block and the gear is used to drive the rotating shaft to drive the support seat to rotate, thereby driving the limited metal plate to rotate and turning the metal plate. Double-sided grinding of the metal plate can be achieved, thereby improving the convenience of the processing process. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] See also Figure 1-Figure 8 The utility model provides the following technical solutions: a metal plate grinding jig, comprising a jig main frame 1, a motor 2 is installed inside the jig main frame 1, a connecting frame 3 is connected to the output end of the motor 2, a mounting ring 4 is installed at the lower end of the connecting frame 3, and a limiting ring 5 is connected to the inner side of the mounting ring 4; a rotating shaft 6 is rotatably connected to the outer side of the mounting ring 4, a support seat 7 is installed at the end of the rotating shaft 6, a limiting seat 8 is sleeved at the end of the supporting seat 7, and the limiting seat 8 is elastically connected to the supporting seat 7 through a first spring 9, a gear 10 is connected to the outer side of the rotating shaft 6, and a positioning hole 11 is opened on the outer side of the rotating shaft 6;

[0029] Furthermore, there is a gap between the connecting frame 3 and the hydraulic rod 19 and the adjusting frame 16, and the lowest point of the adjusting frame 16 in the initial position is higher than the highest point of the fixing plate 12; the mounting ring 4 forms a rotating structure with the fixture main frame 1 through the limiting ring 5, and the support seats 7 are distributed at equal angles on the outside of the mounting ring 4; the end of the support seat 7 passing through the limiting seat 8 is an "I"-shaped structure, the limiting seat 8 and the supporting seat 7 are slidably connected, and the limiting seat 8 and the supporting seat 7 are fixed by bolts;

[0030] The jig main frame 1 is installed in the grinding area, the position of the hydraulic rod 19 corresponds to the position of the grinding mechanism, the metal plate is taken and released at the front station, and the metal plate can be inserted between the limit seats 8. The limit seats 8 can slide at the end of the support seat 7 to adapt to the size of the metal plate. At the same time, the limit seats 8 squeeze and store the first spring 9, and the metal plate is squeezed and fixed by the limit seats 8. Then, the limit seats 8 and the support seats 7 are locked with bolts to complete the fixation of the metal plate. The motor 2 is powered on to control the rotation of the connecting frame 3 connected to the output end, thereby controlling the rotation of the mounting ring 4. At this time, the limit ring 5 rotates on the jig main frame 1 to ensure the stable rotation of the mounting ring 4, feed the metal plate, move the locked metal plate to the grinding mechanism, stop the motor 2, and grind the metal plate. While grinding, the staff can simultaneously unload and load the metal plate to improve the processing rate and sustainably grind the metal plate.
