Description

Technical Field

[0001] The utility model relates to the technical field of workpiece clamping, in particular to a sand box clamping structure for a double-sided milling machine. Background Art

[0002] The sand box is mainly used to make the molds and core boxes required for casting. The two sides of the sand box need to be polished after casting, which is done by a double-sided milling machine. However, during this process, the sand box is placed on the feed conveyor belt, and then the user installs the sand box on the conveyor belt with bolts. The installation position is located on the front and rear sides of the sand box, thereby clamping the sand box.

[0003] Although the above clamping is very simple, there is a problem. After the sand box is placed on the conveyor belt, its position is not parallel to the conveyor belt, that is, the sand box is in a tilted state. Because the sand box is heavy, the user needs to use specific tools to adjust it, which is inconvenient. Therefore, adjusting the position of the sand box has become a technical problem today. In the improvement process, the clamping position is adjusted on the conveyor belt in advance according to the specifications of the sand box, but it still takes a long time to adjust, which greatly prolongs the clamping time of the sand box, and directly affects the overall time for processing both sides of the sand box.

[0004] Therefore, in order to facilitate the clamping of the sand box on the conveyor belt (referred to as the feeding structure in this application), a sand box clamping structure for a double-sided milling machine is proposed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a sand box clamping structure for a double-sided milling machine, which solves the problem that the existing double-sided milling machine cannot clamp the sand box quickly and conveniently when processing the sand box, thereby prolonging the processing time of the sand box.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sand box clamping structure for a double-sided milling machine, comprising a feeding structure located in the middle of the double-sided milling machine, a movable structure is installed on the feeding structure, a rotating structure is installed on the movable structure, the movable structure, the rotating structure and the feeding structure are an integrated structure, the clamping structure is installed on the movable structure, the movable structure comprises a mounting plate installed on the feeding structure, a first groove is symmetrically provided on the surface of the mounting plate, a second guide rail is installed on the surface of the first groove, a sliding block is movably installed on the surface of the second guide rail, a second groove is provided in the middle of the surface of the mounting plate, the clamping structure comprises a bearing seat symmetrically installed on the surface of the second groove, two sets of bearing seats are connected with screws, one end of the screw is connected with a rocker, a second movable plate is movably installed on the surface of the screw, and a clamping plate is installed on the opposite side of the second movable plate. A sand box is placed on the rotating structure, and the front and rear end surfaces of the sand box are in contact with the surface of the clamping plate. The contact between the surface of the clamping plate and the sand box can synchronously drive the movable structure and the rotating structure to move.

[0007] Through the above technical scheme, further, the rotating structure includes a fixed plate installed on the movable structure, the lower end surface of the fixed plate is connected to the surface of the slider, a turntable seat is provided on the surface of the fixed plate, a guide support wheel is symmetrically installed on the upper end surface of the fixed plate, a connecting column is installed on the upper end of the turntable seat, and a placement plate is fixedly installed on the upper end surface of the connecting column.

[0008] Furthermore, the feeding structure includes a CNC milling machine feeding workbench located in the middle of the double-sided milling machine, a fixing frame is symmetrically installed on the upper end of the CNC milling machine feeding workbench, and a connecting frame is symmetrically installed on the opposite side of the fixing frame.

[0009] As a preferred technical solution, a transmission box is installed on the upper end surface of the CNC milling machine feed worktable between the corresponding two groups of connecting frames, an L-shaped mounting plate is installed at the front end of the surface of the CNC milling machine feed worktable, and bearing seats are installed on the inner walls of the front and rear ends of the transmission box. A ball screw is inserted into the transmission box, a servo motor is installed on the front end surface of the L-shaped mounting plate, and a ball screw is connected to the output end of the servo motor.

[0010] Furthermore, a connecting seat is movably mounted on the surface of the ball screw, and a first movable plate is connected to an upper end surface of the connecting seat.

[0011] As a preferred technical solution, a first guide rail is symmetrically installed in the transmission box, and a guide rail guide block is symmetrically installed on the lower end surface of the first movable plate, and the guide rail guide block is movably connected to the surface of the first guide rail.

[0012] Compared with the prior art, the utility model provides a sand box clamping structure for a double-sided milling machine, which has the following beneficial effects:

[0013] 1. This clamping structure refers to Figure 1-4It can be seen that the sand box is placed on the placement plate, and then the rocker is turned to drive the lead screw to rotate, so that the two sets of movable plates are simultaneously moved closer to the middle. At this time, when the clamping plate contacts the sand box, if the sand box is in an inclined state at this time, the placement plate is rotated by the action of the turntable seat during contact until the two sets of clamping plates complete the clamping of the sand box. It should be noted here that if the inclination angle of the sand box is too large, it needs to be adjusted manually, but it does not need to be adjusted too precisely. In this way, the clamping adjustment of the sand box can be achieved more conveniently. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In this embodiment, the specific working principle is: when milling the sand box, place the sand box on the rotating structure, and then the user makes appropriate adjustments according to the placement direction of the sand box, and then rotates the rocker 17 to drive the lead screw 16 to rotate, so that the second movable plate 18 moves closer to the sand box, thereby clamping the sand box through the clamping plate 19.

Then, through the above method, there is no need for excessive human intervention, which solves the problem that the existing double-sided milling machine cannot clamp the sand box quickly and conveniently when processing the sand box, thereby prolonging the processing time of the sand box.
