Description

Technical Field

[0001] This utility model relates to the field of lever clamping shaft processing technology, specifically a lever clamping shaft processing equipment. Background Technology

[0002] The lever clamping shaft (such as a pin or support shaft) is the rotation fulcrum of the clamping mechanism. Through the lever principle, the operating force is amplified or the direction is changed. The shaft acts as a fulcrum, so that the small force applied by the operator, such as rotating the bolt or pressing the force-bearing end, is converted into a larger clamping force, thereby firmly fixing the workpiece.

[0003] For example, a shaft machining fixture with authorization announcement number "CN202607325U" increases the clamping area of ​​the workpiece, thereby increasing the stability of the workpiece clamping and ensuring the machining accuracy of the workpiece. However, this device, by increasing the clamping area of ​​the held shaft, is not convenient for fixed-length cutting. Furthermore, when performing cutting operations, it requires the use of measuring tools, which can be inconvenient. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the device is inconvenient for fixed-length processing, and to propose a lever-clamped shaft processing device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a lever clamping shaft processing device, including a base and support legs. Multiple support legs are fixedly connected to the lower end of the base. The base has a fixed length structure inside. The rear end of the base has a clamping structure. The rear end of the base has a groove. The inner wall of the base has a sliding groove. The upper end of the base has an arc groove.

[0007] Preferably, the clamping structure includes a slide rod and a cross plate. The surface of the slide rod is slidably connected to the base, the upper end of the slide rod is fixedly connected to the cross plate, one end of the cross plate is fixedly connected to the pressure plate, and the lower end of the slide rod passes through the base.

[0008] Preferably, the lower end of the slide rod is fixedly connected to the telescopic end of the electric push rod, and the outer wall of the electric push rod is fixedly connected to the bracket.

[0009] Preferably, both ends of the bracket are fixedly connected to the inner wall of the base.

[0010] Preferably, the fixed-length structure includes a bolt and a crossbar, the outer wall of the crossbar is slidably connected to a groove opened in the inner wall of the base, the right end of the crossbar is fixedly connected to a baffle, and the lower end of the crossbar is abutted against the bolt.

[0011] Preferably, the outer wall of the bolt is threaded to the base, and the surface of the crossbar is provided with engraved lines.

[0012] The lever-clamping shaft processing equipment proposed in this utility model has the following advantages: through the cooperation of the fixed-length structure and the clamping structure, the operator rotates the bolt to separate the upper end of the bolt from the crossbar. The operator pulls the baffle, which can drive the crossbar to move inside the base. By observing the correspondence between the engraved line on the surface of the crossbar and the right end of the base, the distance between the baffle and the right end of the base is fixed. The width consumption of the cutting groove during cutting needs to be taken into account. The baffle limits the movement, making it convenient for the device to perform fixed-length cutting.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] See attached document Figure 1-6In this embodiment, a lever clamping shaft processing device includes a base 1 and support legs 3. Multiple support legs 3 are fixedly connected to the lower end of the base 1. A fixed-length structure 2 is provided inside the base 1. A clamping structure 6 is provided at the rear end of the base 1. A groove is provided at the rear end of the base 1. A sliding groove is provided on the inner wall of the base 1. An arc groove is provided at the upper end of the base 1. The lower end of the sliding rod 601 is fixedly connected to the telescopic end of the electric push rod 4. The outer wall of the electric push rod 4 is fixedly connected to the bracket 5. Both ends of the bracket 5 are fixedly connected to the inner wall of the base 1.

[0022] The clamping structure 6 includes a slide rod 601 and a horizontal plate 603. The surface of the slide rod 601 is slidably connected to the base 1. The upper end of the slide rod 601 is fixedly connected to the horizontal plate 603. One end of the horizontal plate 603 is fixedly connected to the pressure plate 602. The lower end of the slide rod 601 passes through the base 1.

[0023] The fixed-length structure 2 includes a bolt 201 and a crossbar 202. The outer wall of the crossbar 202 is slidably connected to the groove opened in the inner wall of the base 1. The right end of the crossbar 202 is fixedly connected to the baffle 203. The lower end of the crossbar 202 is abutted against the bolt 201. The outer wall of the bolt 201 is threadedly connected to the base 1. The surface of the crossbar 202 is provided with engraved lines.

[0024] Working principle:

[0025] When machining the lever clamping shaft:

[0026] The operator places the longer clamping shaft into the arc-shaped groove at the upper end of the base 1 and controls the electric push rod 4 to work. The telescopic end of the electric push rod 4 shortens, causing the slide rod 601 to move downward. The slide rod 601 can then drive the pressure plate 602 downward through the horizontal plate 603, so that the pressure plate 602 can cooperate with the base 1 to press the longer clamping shaft, thus fixing the clamping shaft. At the same time, the operator can use a handheld cutting device to cut the clamping shaft by placing it against the right end of the base 1.

[0027] Fixed-length process:

[0028] The operator rotates bolt 201 to separate the upper end of bolt 201 from crossbar 202. The operator then pulls baffle 203, allowing baffle 203 to move crossbar 202 inside base 1. By observing the correspondence between the engraved lines on the surface of crossbar 202 and the right end of base 1, the distance between baffle 203 and the right end of base 1 is fixed. The width consumption of the cutting groove during cutting needs to be taken into account (i.e., the cutting length required for baffle 203 to move plus the width of the blade). Baffle 203 is used for limiting the position, making it convenient for this device to perform fixed-length cutting.
