Description

Technical Field

[0001] This utility model relates to the field of double-sided precision grinding machine technology, and specifically to a housing support structure for a double-sided precision grinding machine that can improve stability. Background Technology

[0002] Double-sided precision grinding machines are currently the main equipment for double-sided precision grinding of materials such as cemented carbide, copper sheets, and precision ceramics. Compared to similar machines with gantry-type upper platens, double-sided precision grinding machines with a swing-arm upper platen structure have advantages such as compact structure, ease of cleaning and maintenance, and convenient loading and unloading. In double-sided precision grinding machines with a swing-arm upper platen structure, the machining and assembly accuracy of the upper platen installation position directly determines the stability and machining accuracy of the upper platen. At the same time, ensuring the installation accuracy of each transmission component and the installation position of the limit components also directly affects the stability and machining accuracy of the equipment. Utility Model Content

[0003] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a reasonably designed and easy-to-use box support structure for a double-sided precision grinding machine that can improve stability, thereby effectively solving the defects of the existing technology.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: it comprises a box body, supporting feet, and a top plate; the box body is L-shaped, with supporting feet at each of the four corners of the lower outer bottom wall of the box body, and a top plate fixed to the top wall of the vertical side of the box body; it also comprises:

[0005] The movable plate is embedded in the top wall of the horizontal side of the box body. Sliding plates are fixed at both the front and rear of the movable plate. The sliding plates are slidably disposed in the sliding grooves on the front and rear inner walls of the horizontal plate of the box body.

[0006] An adjusting screw is threaded into one of the sliding plates. Both ends of the adjusting screw are threaded to the two inner walls of the box body through bearings. One end of the adjusting screw is connected to the box body through an adjusting mechanism.

[0007] Rotating screws, there are four rotating screws, and they are screwed into the support feet one by one. After the top of the rotating screw passes through the upper end of the support foot, it is screwed into the bottom wall of the box through the bearing. Several sliding blocks are fixed at equal angles on the outer ring wall of the support foot. The sliding blocks are slidably set in the sliding groove on the inner wall of the bottom plate of the box.

[0008] A rotating mechanism is provided inside the bottom wall of the housing and is connected to four rotating screws.

[0009] The above technical solution fixes the components to the inner bottom wall, top plate, and movable plate of the horizontal side of the housing. During installation, the adjusting mechanism drives the adjusting screw to rotate according to the position of the components inside the horizontal side of the housing. When the adjusting screw rotates, it drives the movable plate to move through the sliding plate, thereby adjusting the position of the movable plate. During use, according to the required height and the unevenness of the ground, the rotating mechanism drives the rotating screw to rotate. The rotating screw drives the support foot to move up and down until the support foot reaches the appropriate position.

[0010] As a further improvement of this utility model, the adjustment mechanism includes:

[0011] Driven gear, the driven gear is sleeved and fixed on the outer end of the adjusting screw, and the driving gear is meshed on the lower side of the driven gear, the diameter of the driving gear is smaller than that of the driving gear;

[0012] A rotating rod is inserted through and fixed to the drive gear. One end of the rotating rod passes through the protective cover and protrudes outside the protective cover. The protective cover is fixed to the outer wall of the box.

[0013] Through the above technical solution, the rotating rod drives the driving gear to rotate, the driving gear drives the driven gear to rotate, and the diameter of the driven gear is larger than that of the driving gear. When the driving gear rotates, the driven gear can rotate slightly, and the driven gear drives the adjusting screw to rotate.

[0014] As a further improvement of this utility model, the rotating mechanism includes:

[0015] The rotating rods consist of four rods, each corresponding to a rotating screw on the side adjacent to the center of the bottom wall of the housing. The rotating rods are connected to the rotating screw via a worm gear pair. The inner end of the rotating rod is screwed into the bottom wall of the housing via a bearing, and the outer end of the rotating rod passes through the bottom wall of the housing and is suspended on the outside of the housing.

[0016] Synchronizing rods, there are four synchronizing rods, and they are symmetrically arranged in pairs on the front and rear sides inside the bottom wall of the housing through bearings. The synchronizing rods are connected to the adjacent rotating rods through bevel gear pairs.

[0017] The linkage rod consists of four rods, which are respectively screwed into the four sides of the bottom wall of the housing via bearings. Movable rotating rods are movably inserted into both ends of the linkage rods. The insert on one end of the outer ring wall of the movable rotating rod is movably inserted into the slot on the inner ring wall of the linkage rod. The insert on the other end of the outer ring wall of the movable rotating rod is engaged with the slot on the inner ring wall of the adjacent rotating rod and the synchronizing rod.

[0018] The push mechanism consists of four parts, each located within one of the four sides of the bottom wall of the housing. The push mechanism is connected to the movable rotating rod.

[0019] With the above technical solution, when the height of a single support foot needs to be adjusted, the corresponding rotating rod is rotated. The rotating rod drives the connected rotating screw to rotate through the worm gear pair, thereby adjusting the position of the support foot. When synchronous adjustment is required, the pushing mechanism is activated. The pushing mechanism drives the movable rotating rod to move, so that the movable rotating rod is inserted into the corresponding rotating rod and the synchronizing rod. At this time, only one rotating rod needs to be rotated to synchronously drive the other several rotating rods to rotate.

[0020] As a further improvement of this utility model, the driving mechanism includes:

[0021] A push rod is movably inserted into the bottom wall of the box, and a push plate is provided at the inner end of the push rod, which is movably disposed in the bottom wall of the box.

[0022] The push link consists of two links, each of which is screwed onto the side wall of the push plate away from the push rod via a hinge seat. A push ring is screwed onto the other end of the push link via a hinge seat. The push ring is sleeved on and screwed onto the middle end of the movable rotating rod via a bearing.

[0023] A positioning mechanism is provided inside the bottom wall of the housing and is connected to the push rod;

[0024] Through the above technical solution, the push rod is pushed into the inside of the box, and the push rod drives the push plate to move to one side of the center of the box. During the movement, the push plate drives the push connecting rods on both sides to rotate. When the push connecting rods rotate, they drive the push ring to move to both sides until the movable rotating rod is inserted into the corresponding rotating rod and the synchronizing rod, and is positioned by the positioning mechanism.

[0025] As a further improvement of this utility model, the positioning mechanism includes:

[0026] The mounting plate is embedded and fixed in the bottom wall of the box. The mounting plate is located between two push rods. Several abutment springs are fixed at equal intervals on one side wall of the mounting plate. The other end of the abutment spring is fixed to the push plate adjacent to it.

[0027] The positioning plate is fixed on the upper side of the outer ring wall of the push rod. The positioning plate is inserted into a slot on one side of the bottom wall of the box. A limit groove is provided on one side of the inner wall of the slot. The positioning plate is inserted into the limit groove.

[0028] With the above technical solution, when synchronous rotation is required, the push rod drives the positioning plate to move into the bottom wall of the box, and at the same time the push plate abuts against the anti-spring until the positioning plate reaches one side of the limiting groove. Then the push rod is rotated, and the push rod drives the positioning plate to rotate, so that the positioning plate rotates into the limiting groove, thereby limiting the push plate.

[0029] As a further improvement of this utility model, a rotating handle is sleeved and fixed on the outer end of the push rod, and the rotating handle is suspended on the outside of the box body; this facilitates the rotation of the push rod.
