Description

Technical Field

[0001] This utility model relates to the field of grinding machinery and equipment technology, specifically to an adjustable double-sided precision grinding machine upper support structure. Background Technology

[0002] A double-sided precision grinding machine upper support structure disclosed in patent publication number CN218697552U describes a structure in which "a support frame is mounted on a receiving base, a mounting component is mounted on the support frame, a motor is mounted on the mounting component, a lead screw passes through the support frame and is mounted on the motor, a limiting groove is mounted on the support frame, and a sliding component is slidably mounted on the limiting groove and the lead screw." Although the patent uses a motor to drive the lead screw to rotate, thereby moving the sliding component and thus the equipment mounting frame, dust generated during the grinding process can enter the limiting groove and onto the lead screw, affecting the lead screw transmission and thus the movement of the equipment mounting frame. Utility Model Content

[0003] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing an adjustable support structure for a double-sided precision grinding machine that is simple in structure, reasonable in design, and easy to use. The structure that drives the sliding block to move is located on the right side of the support frame, which is not affected by dust and therefore does not affect the movement of the equipment mounting frame.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: it includes a workbench, an equipment mounting frame, and a support frame. An electromagnetic chuck is fixedly installed on the upper left side of the workbench, a support frame is installed on the upper side of the workbench, a sliding block is installed on the left side of the support frame, and an equipment mounting frame is installed on the left side of the sliding block.

[0006] The movable frame consists of two movable frames, which are symmetrically fixed on the front and rear sides of the sliding block; and the movable frames are U-shaped, with each movable frame movably engaged on the front and rear sides of the support frame.

[0007] A fixed guide frame is fixedly installed on the right side of the support frame, and a movable block is slidably inserted inside the fixed guide frame;

[0008] The connecting frame has a "U" shaped structure. The connecting frame is movably connected to the right side of the fixed guide frame, and the horizontal ends of the front and rear sides of the connecting frame are respectively connected to the corresponding movable frames. The inner wall of the right side of the connecting frame is connected to the movable block.

[0009] The connecting frame is fixedly installed on the right side of the support frame and is located on the lower side of the fixed guide frame.

[0010] The drive motor is fixedly mounted on the outer right side of the connecting frame. After the output shaft of the drive motor passes through the outer right side of the connecting frame, a drive shaft is provided. A drive gear is sleeved and fixed on the drive shaft. A driven gear is meshed on one side of the drive gear. A driven shaft passes through and is fixed inside the driven gear. The right end of the driven shaft is screwed onto the inner right side of the connecting frame through a bearing.

[0011] Two rotating disks are fixedly mounted on the left ends of the drive shaft and the driven shaft, respectively, and the rotating disks are located on the left side of the drive gear and the driven gear.

[0012] The connector consists of two parts, which are respectively hinged to the left side of the rotating disk via hinge shafts, and the upper end of the connector is hinged to the right side of the connecting frame via hinge shafts.

[0013] Through the above technical solution design, the drive motor drives the active gear to rotate, which meshes with the driven gear to rotate, so that the two rotating disks rotate relative to each other at the same time, causing the connecting parts to rotate, thereby driving the connecting frame. The sliding cooperation between the moving block and the fixed guide frame guides the connecting frame, thereby driving the movable frame and the sliding block.

[0014] As a further improvement of this utility model, a guide rod is fixedly provided inside the fixed guide frame, and the guide rod passes through the moving block;

[0015] The above technical solution is used to reinforce and guide the moving block.

[0016] As a further improvement of this utility model, guide rails are fixedly provided on both the front and rear sides of the support frame, and the movable frame is slidably disposed on the guide rails.

[0017] The above technical solution design guides the movement of the movable frame, making its movement more stable.

[0018] As a further improvement of this utility model, a support block is fixedly installed on the upper side of the workbench. The support block is located on the right side of the electromagnetic chuck, and the support frame is slidably installed on the upper side of the support block through a sliding pair. A support plate is fixedly installed on the upper side of the support block with the front and rear sides facing each other. A support shaft is screwed through the support plate on the front side through a bearing. A rotating wheel is fixedly installed at the front end of the support shaft. A positioning pin passes through the rotating wheel and is inserted into the support plate. A screw is fixedly installed at the rear end of the support shaft. The screw is screwed through the support frame through a thread, and the rear end of the screw is screwed into the support plate on the rear side through a bearing.

[0019] Through the above technical solution design, the rotary wheel is manually rotated, causing the screw to rotate, which drives the support frame, moves the equipment mounting frame, and positions it through the positioning pin.

[0020] As a further improvement of this utility model, a handle is provided on the outer side of the wheel;

[0021] The above technical solution is designed to enable the rotating wheel to rotate.

[0022] As a further improvement of this utility model, a partition is provided on the upper side of the workbench, and the partition is located between the support block and the electromagnetic chuck.

[0023] The above technical solution design creates a gap between the support block and the electromagnetic chuck.

[0024] The working principle of this utility model is as follows: Starting the drive motor drives the active gear to rotate, which in turn meshes with the driven gear, causing the active and driven shafts to rotate relative to each other simultaneously. This causes the two rotating discs to rotate relative to each other, resulting in the rotation of the connecting parts, which in turn drives the connecting frame. The sliding engagement between the moving block and the fixed guide frame guides the connecting frame, driving the movable frame and the sliding block to move the equipment mounting frame up and down, changing the position of the grinding wheel. Next, manually rotating the handle rotates the screw, which in turn drives the support frame, causing the equipment mounting frame to move back and forth, thus moving the grinding wheel back and forth. Finally, the rotating wheel is locked in place by a positioning pin, fixing the support frame in position.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] 1. By setting movable frames on the front and rear sides of the sliding block, the movable frames are movably locked onto the support frame, and the two movable frames are connected by a connecting frame.

[0027] 2. The driving shaft and the driven shaft rotate simultaneously through the meshing of the driving gear and the driven gear, and the connecting parts drive the connecting frame through the hinged setting of the hinge shaft.

[0028] 3. During the movement of the connecting frame, in addition to being guided by the sliding between the moving block and the fixed guide frame, the movement of the moving block is also guided by the guide rod. Furthermore, in addition to sliding and locking with the support frame, the movable frame is also guided by the guide rail, which strengthens the stability of the connecting frame and the movable frame during movement.

[0029] 4. Add a support block to the lower side of the support frame, and use a threaded drive to move the support frame on the support block, so that the equipment mounting frame can be moved back and forth for adjustment. Attached Figure Description
