DETAILED DESCRIPTION

[0024] The above and other technical contents, features and functions of the present invention are described in detail below with reference to the attached Figure 1-3 The detailed description of the embodiments will clearly show that the structural contents mentioned in the following embodiments are all based on the drawings in the specification.

[0025] Various exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.

[0026] Embodiment 1, a clamping device for stone grinding, including a support frame 1 and a rotating frame 2, characterized in that:

[0027] The rotating frame 2 is rotatably connected to the supporting frame 1, and the rotating frame 2 is driven by a first power device.

[0028] Two groups of transverse clamping plates 3 are slidably connected on the rotating frame 2, and the two groups of transverse clamping plates 3 are driven by a second power device;

[0029] The rotating frame 2 is provided with two groups of connecting plates 4, and the two groups of connecting plates 4 are provided with first telescopic rods 5, and the output ends of the first telescopic rods 5 are connected to auxiliary plates 6;

[0030] The auxiliary plate 6 is slidably connected to a guide rod 7, one end of the guide rod 7 is connected to a limit plate 8, and the other end is provided with a longitudinal clamping plate 9, the auxiliary plate 6 is threadedly connected to a screw 10, one end of the screw 10 is provided with a handle 11, and the other end is rotatably connected to the longitudinal clamping plate 9;

[0031] The first power device comprises a motor 12 provided on the support frame 1, the rotating frame 2 is driven by the motor 12, and the motor 12 is electrically connected to the controller;

[0032] The second power device comprises two groups of mounting grooves 13 provided on the rotating frame 2, and the two groups of mounting grooves 13 are both provided with second telescopic rods 14;

[0033] The two groups of transverse clamping plates 3 are slidably connected to the inner side wall of the rotating frame 2, and the transverse clamping plates 3 are connected to the output end of the second telescopic rod 14;

[0034] The minimum stroke height of the first telescopic rod is not less than the height of the transverse clamping plate 3, and the transverse length of the longitudinal clamping plate 9 is not less than the vertical distance between the two sets of transverse clamping plates 3;

[0035] An anti-slip pad 15 is provided between the transverse clamping plate 3 and the longitudinal clamping plate 9;

[0036] The first telescopic rod and the second telescopic rod are both bidirectional electric telescopic rods, and the first telescopic rod and the second telescopic rod are electrically connected to the controller;

[0037] The support frame 1 includes a support rod 16, a base 17 and a support plate 18. The support rod 16 is provided between the support plate 18 and the base 17. The base 17 is a shock-absorbing seat. The shock-absorbing seat is a device used to reduce the vibration transmission of mechanical equipment or structures. Its main purpose is to protect the equipment or structure, reduce the impact of vibration on the surrounding environment, and extend the service life of the equipment. It is usually composed of springs, rubber or other elastic materials, and can absorb and disperse vibration energy. However, the shock-absorbing seat of the present application adopts a method of providing rubber at the bottom of the base for shock absorption;

[0038] The support rod 16 is a retractable support rod. An electric retractable rod or a hydraulic retractable rod is arranged between the support plate 18 and the base 17, so that the overall height of the equipment can be adjusted, so that it is suitable for operators of different heights, easy to adjust, and convenient to operate.

[0039] When in use, place the stone in the center of the rotating frame 2. Since the middle of the rotating frame 2 is hollow, place the stone in the hollow position of the rotating frame 2 so that the stone is located between the two sets of horizontal clamping plates 3 and the two sets of longitudinal clamping plates 9.

[0040] The first telescopic rod 5 is a bidirectional electric telescopic rod. By driving the first telescopic rod 5, two sets of auxiliary plates 6 connected to the output end of the first telescopic rod 5 can be driven to move. The two sets of auxiliary plates 6 move to adjust the clamping height of the longitudinal clamping plate 9, so as to be suitable for stones of different thicknesses. The operation is simple and the adjustment is convenient.

[0041] By rotating the handle 11, the screw rod 10 is driven to move. Since the screw rod 10 is threadedly connected to the auxiliary plate 6, and one end is rotatably connected to the back of the longitudinal clamping plate 9, the handle 11 can be rotated under the action of the guide rod 7 to adjust the longitudinal distance of the longitudinal clamping plate 9, which is suitable for stones of different widths, simple to operate and easy to adjust;

[0042] The second telescopic rod 14 is a bidirectional electric telescopic rod. By driving the second telescopic rod 14, the two sets of transverse clamping plates 3 can be driven to slide along the inner wall of the rotating frame 2, so as to be suitable for stones of different lengths. The operation is simple and the adjustment is convenient.

[0043] Through the above operation, under the action of the transverse clamping plate 3 and the longitudinal clamping plate 9, the stone can be clamped. The grinders are arranged in two groups, and the two groups of grinders are arranged at the top and bottom of the rotating frame 2 respectively. The grinding discs of one group of grinders are fine grinding discs, and the grinding discs of the other group of grinders are coarse grinding discs.

[0044] After the stone is installed, the grinding heads of the two grinding machines can be made to correspond to the top and bottom of the stone by driving the two sets of telescopic rods. The reciprocating motion of the grinding discs can be achieved by moving the mounting plate to grind the entire stone surface. The grinding thickness can be adjusted by driving the two sets of telescopic rods.

[0045] When grinding, the top of the stone is firstly rough-grinded. After grinding, the rotating frame 2 is rotated by driving the motor 12 so that the rough-grinded surface corresponds to the grinder at the bottom. By driving one set of telescopic rods, the grinder at the bottom corresponds to the stone for fine grinding, while the top of the stone is rough-grinded.

[0046] In this way, the grinding efficiency is improved, and the time for disassembly and installation is saved. The problem that the current imitation stone needs to press the clamp on the top of the imitation stone blank during grinding, and then perform rough grinding and then fine grinding, and needs to use different equipment or replace equipment for grinding; in this process, the stone needs to be frequently disassembled, installed and positioned, which makes the operation steps cumbersome and reduces the grinding efficiency.

[0047] The above description is only for illustrating the present invention, and it should be understood that the present invention is not limited to the above embodiments, and various variations that conform to the concept of the present invention are within the protection scope of the present invention.
