Description

Technical Field

[0001] This utility model belongs to the field of tappet technology and relates to a fixture for tappets. Background Technology

[0002] Hydraulic tappets are frequently used in engine valve trains. The hydraulic tappet pushes the valve stem by the pressure difference of the hydraulic oil in the internal cavity, thereby achieving the valve opening process.

[0003] Currently, when machining hydraulic tappets, it is necessary to use fixtures to clamp and fix them to prevent the hydraulic tappets from moving during machining, thereby improving the machining efficiency and accuracy of hydraulic tappets. However, existing tappets still have the defect of unstable positioning when positioned on fixtures. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a clamping fixture for pushrods that provides more stable workpiece clamping.

[0005] The objective of this utility model can be achieved through the following technical solution: A clamping fixture for a pushrod includes a worktable, characterized in that a positioning seat is fixedly disposed on the right side of the worktable, a clamping seat that cooperates with the positioning seat and is used to clamp the workpiece is disposed on the left side of the worktable, a positioning post for positioning the workpiece is disposed on the worktable, and the clamping seat is composed of a clamping member, a connecting rod and a fixed seat. A connecting spring is sleeved on the connecting rod. The two ends of the connecting spring are respectively connected to the fixed seat and the clamping member. The clamping member is connected to the fixed seat through the connecting rod and cooperates with the positioning seat on the worktable to clamp the workpiece. The positioning seat, clamping seat and positioning post form a clamping space for the push rod to clamp and process. The fixed seat is provided with a connecting part. The connecting part of the fixed seat is provided with a positioning component to reinforce the positioning of the clamping member. The positioning component consists of a positioning rod and a return spring. The clamping member is provided with a positioning hole that matches the positioning member. The connecting part is provided with an installation groove for the positioning component to be installed. The positioning rod matches the positioning hole through the action of the return spring to position the clamping member.

[0006] In the aforementioned clamping fixture for a pushrod, both the clamping element and the positioning seat are provided with arc-shaped grooves that match the workpiece.

[0007] In the aforementioned clamping fixture for a push rod, the fixed seat is configured in an L-shape, and the upper end of the fixed seat is provided with a mounting part, which is integrally formed with the fixed seat. The length of the mounting part is greater than the clamping distance of the clamping member.

[0008] In the aforementioned clamping fixture for a tappet, the worktable has several openings.

[0009] Compared with existing technologies, the clamping seat in this tappet fixture positions the clamping component through a positioning component when clamping the workpiece, thus avoiding the instability of workpiece processing caused by external influences on the clamping component. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the structure of this utility model.

[0011] Figure 2 This is a cross-sectional structural diagram of the present invention.

[0012] In the diagram, 1 is the worktable; 2 is the positioning seat; 3 is the clamping seat; 4 is the positioning column; 5 is the clamping component; 6 is the connecting rod; 7 is the fixed seat; 8 is the connecting spring; 9 is the connecting part; 10 is the positioning rod; 11 is the sliding part; and 12 is the return spring. Detailed Implementation

[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0014] like Figure 1 , Figure 2 As shown, this clamping fixture for the push rod includes a worktable 1. A positioning seat 2 is fixedly installed on the right side of the worktable 1, and a clamping seat 3 is installed on the left side of the worktable 1, which cooperates with the positioning seat 2 and is used to clamp the workpiece. A positioning post 4 for workpiece positioning is provided on the worktable 1. The clamping seat 3 consists of a clamping member 5, a connecting rod 6, and a fixed seat 7. A connecting spring 8 is sleeved on the connecting rod 6, and the two ends of the connecting spring 8 are respectively connected to the fixed seat 7 and the clamping member 5. The clamping member 5 is connected to the fixed seat 7 through the connecting rod 6 and cooperates with the positioning seat 2 on the worktable 1. The positioning seat 2, clamping seat 3, and positioning post 4 form a clamping space for the push rod to clamp and process the workpiece. The fixed seat 7 is provided with a connecting part 9. The connecting part 9 of the fixed seat 7 is provided with a positioning assembly for positioning by reinforcing clamping member 5. The positioning assembly consists of a positioning rod 10 and a return spring 12. The clamping member 5 is provided with a positioning hole that matches the positioning member. The connecting part 9 is provided with an installation groove for installing the positioning assembly. The positioning rod 10 matches the positioning hole through the action of the return spring 12 to position the clamping member 5.

[0015] To elaborate further, when the workpiece needs to be processed, by pulling the clamping member 5 and the positioning rod 10, the clamping member 5 moves to the left and the positioning rod 10 moves upward. Both the connecting spring 8 and the return spring 12 are in a compressed state. Then, the workpiece is installed in the clamping space, the connecting spring 8 returns to its original position, the clamping member 5 moves to the right and abuts against the workpiece, thereby positioning the workpiece. After the workpiece is positioned, the positioning rod 10 is released, the return spring 12 returns to its original position, the positioning member moves downward and extends into the positioning hole, thereby fixing the clamping member 5.

[0016] To elaborate further, both the clamping component 5 and the positioning seat 2 are provided with arc-shaped grooves that match the workpiece.

[0017] To elaborate further, the fixing base 7 is arranged in an L-shape. The upper end of the fixing base 7 is provided with a mounting part, which is integrally formed with the fixing base 7. The length of the mounting part is greater than the clamping distance of the clamping member 5.

[0018] To elaborate further, the workbench 1 has several openings.

[0019] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0020] Although this document frequently uses terms such as worktable 1, positioning seat 2, clamping seat 3, positioning post 4, clamping component 5, connecting rod 6, fixing seat 7, connecting spring 8, connecting part 9, positioning rod 10, sliding part 11, and return spring 12, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
