Technical Field

[0001] The utility model relates to the technical field of self-propelled gun firepower system maintenance equipment, in particular to a universal debugging platform for a self-propelled gun firepower system. Background Art

[0002] The entire army is currently equipped with a variety of typical self-propelled artillery, but lacks a suitable comprehensive test bench for the firepower system. At the same time, the technical support during the repair process of self-propelled artillery units also requires more advanced testing and repair equipment.

[0003] Since the sizes of various types of turret seat rings are different, in order to make the platform applicable to various artillery turrets, three different specifications of platform seat rings need to be made. This not only wastes a lot of raw materials, is difficult to process, handle, and store, but also is inconvenient to operate and use. Utility Model Content

[0004] In view of the deficiencies of the existing technology, the utility model provides a universal debugging platform for the firepower system of a self-propelled artillery, which can meet the needs of repairing the existing self-propelled equipment turret.

[0005] The utility model is achieved through the following technical solutions:

[0006] A universal debugging platform for a self-propelled artillery firepower system is provided, comprising a base ring and two support beams symmetrically arranged below the base ring, the two support beams having one end on the same side being connected by a connecting beam, the base ring being rotatably installed between the support beams by a tilting mechanism, the tilting mechanism comprising a flip shaft, a bearing seat and a flip cylinder, two flip shafts being provided and located on the same straight line, the two flip shafts being installed on the bottom surface of the base ring through a connecting seat, the bearing seat being installed on the support beam opposite to the connecting seat and cooperating with the flip shaft for rotation, the flip cylinders being respectively arranged on the same side of the two flip shafts, the two ends of the flip cylinders being respectively hinged to the support beam and the base ring; a plurality of chuck assemblies arranged at intervals are installed on the surface of the base ring, each chuck assembly being connected to a claw block movable along the radial direction of the base ring; columns are vertically arranged at both ends of each support beam, each column is connected to a lifting frame sleeved on the circumference of the column by a screw nut lifting mechanism, and each lifting frame is connected to the corresponding end of the support beam by a lifting fine-tuning mechanism.

[0007] Furthermore, adjacent chuck assemblies are arranged at equal intervals.

[0008] The chuck components are installed on the base ring at equal intervals, which makes it easy to clamp and fix various platform seats and ensures the stability of clamping.

[0009] Furthermore, the chuck assembly includes a guide block, a slider and a chuck driving mechanism. The guide block is installed on the surface of the base ring. A slide groove is provided on the surface of the guide block along the radial direction of the base ring, and an avoidance groove is provided on the bottom surface of the slide groove along the length direction. The slider is slidably arranged in the slide groove and connected to the claw block. The chuck driving mechanism includes a rack arranged in the avoidance groove and fixed on the bottom surface of the slider.

A driving gear and a driven gear that mesh with each other are rotatably installed on the gear seat. The driven gear is engaged with the rack, and a self-locking operating lever is installed on the rotating shaft of the driving gear.

[0010] The slider is connected to the claw block. The slider slides in the guide block to achieve clamping and loosening of the claw block. The operating lever is used to operate the driving gear to drive the driven gear, and then the driven gear is engaged with the rack on the bottom surface of the slider to achieve transmission.

[0011] Furthermore, the screw nut lifting mechanism includes a lifting screw vertically mounted in the inner cavity of the column, and a lifting motor vertically mounted at the lower end of the column through a mounting base. The lifting screw is threadedly connected to a lifting nut connected to the lifting frame, and the lifting motor is connected to one end of the lifting screw through a sprocket chain transmission assembly.

[0012] The lifting screw of the screw nut lifting mechanism is driven by a lifting motor, and the lifting frame sliding sleeve is arranged on the outside of the column. When the lifting screw rotates, the lifting frame connected to the lifting nut follows the lifting nut and moves up and down along the length direction of the lifting screw to achieve the lifting effect of the lifting frame.

[0013] Furthermore, the column is a fixed frame with a Π-shaped cross-section, the lifting frame is a fixed sleeve with a rectangular cross-section, the upper and lower ends of the lifting screw are rotatably installed in the fixed frame through support plates, the lifting nut is connected to the inner wall of the fixed sleeve through the opening of the fixed frame through a connecting rod, and the two inner walls of the fixed sleeve facing the fixed frame are rotatably installed with rollers that can roll with the outer wall of the fixed frame.

[0016] The lower end of the column is connected to the base, and the base is used to increase the contact area between the column and the ground, thereby improving the overall stability.

[0017] Furthermore, the lifting and fine-tuning mechanism includes a lifting rod, a fine-tuning screw and a fine-tuning nut. The lifting rod is arranged vertically, and a ball head is provided at its upper end and is hinged to the bottom surface of the end of the support beam through a spherical hinge. The fine-tuning screw is coaxially arranged with the lifting rod and the fine-tuning screw is connected to the lower end of the lifting rod. The fine-tuning nut is fixed on the lifting frame and cooperates with the fine-tuning screw thread.

[0018] The lifting rod is spherically hinged to the bottom surface of the support beam through the ball head. The lower end of the lifting rod is connected to the fine-tuning screw, which is threadedly connected to the fine-tuning nut. The height of the lifting rod is adjusted by rotating the fine-tuning screw, and the height of the support frame is then driven by the lifting rod.

[0019] Furthermore, the outer wall of the lifting frame is vertically connected to an open support tube located below the end of the support beam through a connecting plate. The fine-tuning nut is fixed to the inner bottom of the support tube. The lower end of the lifting rod is provided with a sliding part and is slidably supported in the support tube. The upper end of the sliding part is provided with a support boss integrally formed with the sliding part and used to support the lifting rod at the open end of the support tube. The lower end of the fine-tuning screw passes through the guide tube and is connected to a fine-tuning handle.

[0020] The lower end of the lifting rod is matched with the inner wall of the support tube and can be slid up and down in the guide tube. The fine-tuning nut is fixed to the inner bottom of the support tube. By rotating the fine-tuning screw, the fine-tuning screw can be used to apply force to the lifting rod, thereby adjusting the length of the sliding part of the lifting rod in the support tube, thereby achieving fine-tuning of the height position of the lifting rod and the upper support beam.

[0021] Furthermore, an auxiliary support rod is hingedly arranged between the outer wall of the support tube and the end of the support beam.

[0022] By tilting and hingedly connecting the auxiliary support rod between the outer wall of the support tube and the bottom surface of the support beam, the stability of the overall connection can be improved, ensuring the stability of the support beam on the column during adjustment.

[0023] Beneficial effects of the utility model:
