Technical Field

[0001] This utility model relates to the field of piston processing technology, specifically to a drilling device for a variable piston. Background Technology

[0002] A variable displacement piston is a key component in a hydraulic system used to regulate the displacement of a pump or motor. Flow rate can be adjusted by changing the piston stroke or tilt angle. A variable displacement piston is cylindrical and includes a piston top, a piston head, a piston skirt, piston ring grooves on the sidewall of the piston head, and a piston pin seat on the sidewall of the piston skirt. The piston pin seat is used to insert a piston pin, which connects to the connecting rod below.

[0003] Therefore, drilling is required on the side of the piston during the manufacturing process of variable pistons. Existing drilling devices mainly consist of a base, a clamping mechanism, a drill bit, and a drive mechanism. The piston is clamped in the clamping mechanism on the base, and the drill bit is driven to rotate and move via the drive mechanism to drill a hole on the side of the piston. However, this method has the following drawbacks:

[0004] 1. Because the outer wall of the piston is curved, the drill bit will be misaligned when drilling on the circumferential surface, making drilling difficult;

[0005] 2. The clamping mechanism can only clamp one piston at a time, resulting in low production efficiency. Utility Model Content

[0006] I. Technical problems to be solved

[0007] The technical problem to be solved by this invention is the problem of easy deviation during drilling and low drilling efficiency.

[0008] II. Technical Solution

[0009] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a drilling device for a variable piston, including an operating table;

[0010] The operating table is provided with front and back opposite pads. The upper surface of the pads is a concave curved surface in the front and back direction, and the height of one end is less than the height of the other end.

[0011] The operating table has left and right grooves on its front and rear side walls. An inverted U-shaped support plate located above the operating table is slidably arranged between the two grooves. A telescopic rod with front and rear opposite sides is fixedly connected to the top of the support plate. The lower end of the telescopic rod passes through the support plate and is connected to a horizontal plate. A motor is installed on the horizontal plate. The output end of the motor passes through the horizontal plate and is connected to a drill bit. A second telescopic rod with front and rear opposite sides is fixedly connected to the lower side of the horizontal side of the support plate. The lower end of the second telescopic rod passes through the horizontal plate and is connected to a pressure plate.

[0012] One of the telescopic poles and both of the telescopic poles mentioned are electric telescopic poles.

[0013] As an improvement, the left and right corners at the upper end of the pad are rounded.

[0014] As an improvement, a left-right screw is provided in the groove on the front side, one end of the screw passes through the operating table and is connected to a second motor, and the support plate is threaded onto the outside of the screw.

[0015] As an improvement, a horizontal bar extending to the left and right through the support plate is provided in the groove located on the rear side.

[0016] As an improvement, a spring is provided between the support plate and the horizontal plate, which is sleeved on the telescopic rod.

[0017] As an improvement, the left and right ends of the operating table are provided with C-shaped rods with their ends facing the center of the operating table. The upper end of the C-shaped rod is located between the pads and connected to a limit block, and the lower end is connected to a telescopic rod three.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0029] As attached Figure 1-4 As shown, a drilling device for a variable piston includes an operating table 1. Above the operating table 1 are two opposing pads 2. The upper surface of the pads 2 is a concave curved surface in the front-back direction, and the height of one end is less than the height of the other end, forming a curved surface fit support with the piston, so that the piston is located between the two pads 2, and multiple pads can be placed.

[0030] Furthermore, the left and right corners of the upper end of the pad 2 are rounded to prevent the edge of the pad 2 from hitting the piston and the operator, thus improving safety.

[0031] The operating table 1 has left and right grooves 3 on its front and rear side walls. An inverted U-shaped support plate 4 is slidably mounted between the two grooves 3 above the operating table 1. A left and right screw 11 is located in the groove 3 on the front side. One end of the screw 11 passes through the operating table 1 and is connected to a motor 12. The support plate 4 is threaded onto the outside of the screw 11. By starting the motor 12, the screw 11 can be rotated. The support plate 4 moves horizontally left and right with the rotation of the screw 11. A horizontal rod 13 is located in the groove 3 on the rear side and passes through the support plate 4. The horizontal rod 13 further restricts the support plate 4 to move horizontally left and right.

[0032] The support plate 4 is fixedly connected to a front-to-back telescopic rod 5. The lower end of the telescopic rod 5 passes through the support plate 4 and is connected to a horizontal plate 6. A motor 7 is installed on the horizontal plate 6. The output end of the motor 7 passes through the horizontal plate 6 and is connected to a drill bit 8. The support plate 4 is fixedly connected to a front-to-back telescopic rod 9 on the lower side of the horizontal side. The lower end of the telescopic rod 9 passes through the horizontal plate 6 and is connected to a pressure plate 10. One of the telescopic rods 5 and the two telescopic rods 9 are all electric telescopic rods. The pressure plate 10 is a downwardly curved arc plate structure with anti-slip texture on the lower surface, which can fit against the upper surface of the piston. The anti-slip texture increases the friction. The upper arc-shaped pressure plate 10 is controlled by the telescopic rod 9, so that the pressure plate 10 cooperates with the pad plate 2 to stabilize and fix the position of the piston. The telescopic rod 5 controls the horizontal plate 6 up and down, that is, controls the drill bit 8 up and down. After starting the motor 7, a hole can be drilled on the piston surface to avoid drilling deviation.

[0033] Furthermore, a spring 14 is provided between the support plate 4 and the horizontal plate 6, which is sleeved on the telescopic rod 5 to buffer the drilling force.

[0034] Furthermore, the operating table 1 is provided with C-shaped rods 15 at both ends, with the ends facing the center of the operating table 1. The upper end of the C-shaped rod 15 is located between the pads 2 and connected to the limit block 17, and the lower end is connected to the telescopic rod 16. The telescopic rod 16 is an electric telescopic rod and is connected to the bottom of the operating table 1. Multiple pistons placed on the pads 2 can be limited by the limit block 17. In conjunction with the left and right sliding support plate 4, the drill bit 8 is moved. The telescopic rod 5 controls the drill bit 8 to press down, so as to automatically drill continuously, reduce the number of clamping times, and improve drilling efficiency.

[0035] It is worth noting that the power supply and control switch of the electrically driven component mentioned in this embodiment can also be provided by the manufacturer. The circuits, electronic components and modules involved are all existing technologies. They can be connected to the external power supply by wired means, which are existing methods and will not be described in detail. Those skilled in the art can fully implement them without further explanation.
