Description

Technical Field

[0001] This utility model relates to the field of workpiece surface treatment technology, specifically to a clamping mechanism for workpiece surface treatment. Background Technology

[0002] Surface treatment is a process that artificially forms a layer on the surface of a base material that has different mechanical, physical, and chemical properties from the base material. The purpose of surface treatment is to meet the corrosion resistance, wear resistance, decorative, or other special functional requirements of a product. For metal castings, commonly used surface treatment methods include mechanical grinding, chemical treatment, surface heat treatment, and surface coating. Surface treatment involves cleaning, sweeping, deburring, removing oil stains, and removing oxide scale from the workpiece surface.

[0003] Patent specification CN106514790A discloses a method for positioning and clamping a low-hardness workpiece surface, comprising an upper clamping arm, a connecting arm, and a lower clamping arm connected in sequence. A screw hole with an internal thread is provided at the end of the lower clamping arm away from the connecting arm. A screw rod is installed in the screw hole, and the external thread on the surface of the screw rod matches the internal thread of the screw hole. A clamping plate is provided at the top of the screw rod. A pressure plate is provided on the clamping surface of the upper clamping arm, and the lower surface of the pressure plate is parallel to the upper surface of the clamping plate. By increasing the pressure area on the workpiece, the pressure on the stop bar or workpiece surface is reduced, preventing the wood material from deforming or even being damaged under external force. The method also increases the contact area between the clamping plate and the bottom of the planer platform, reducing the possibility of slippage.

[0004] However, during the implementation of the relevant technology, the following problems were found with the above technical solution: In the process of use, the above device increases the pressure area of ​​the workpiece, reduces the pressure on the baffle or the surface of the workpiece, and avoids the deformation or even damage of the wood material under the action of external force. It also increases the contact area between the clamping plate and the bottom of the planer platform, reducing the possibility of slippage. However, the above device can only limit the clamping of the two sides of the workpiece, and cannot effectively clamp the other orientations of the workpiece. This makes it risky for the workpiece to fall off the clamping device when it is squeezed by external force. Therefore, further improvement is needed. Utility Model Content

[0005] This utility model proposes a clamping mechanism for workpiece surface treatment, which solves the problem in related technologies that make it inconvenient to stably clamp the workpiece from all sides.

[0006] The technical solution of this utility model is as follows:

A limiting component is provided on the outer surface of one end of the operating table. An auxiliary component is slidably provided inside the limiting component for cooperating with the parts of the clamping component to limit and fix the upper position of the workpiece, and a fixing component is used to fix the auxiliary component on the limiting component to prevent the auxiliary component from moving again.

[0008] Preferably, the clamping component includes a sliding groove formed on the side of the operating table, a horizontal groove formed at the upper end of the operating table, a support member slidably connected inside the operating table, a pull rod fixedly connected to one side of the lower end of the support member, a clamping plate fixedly connected to one side of the support member, a rope fixedly connected to the upper end of the clamping plate, a collar fixedly connected to one end of the rope, and a support plate fixedly connected to one side of the lower end of the clamping plate.

[0009] Preferably, the transverse groove is connected to the slide groove, the lower end of the support member is slidably connected to the transverse groove, the pull rod passes through the slide groove, and one end of the support plate passes through one side of the operating table.

[0010] Preferably, the limiting component includes a circular groove evenly formed on one side of the operating table, a vertical groove formed on the outer side of the operating table, a slot evenly formed on the side wall of the vertical groove, an opening formed on the side wall of the slot, a limiting groove and an annular groove formed on the inner wall of the opening, the side wall of the vertical groove being connected to the circular groove, and the opening correspondingly being connected to the circular groove.

[0011] Preferably, the auxiliary component includes an auxiliary block slidably connected to the inner wall of the vertical groove, a through groove is formed on one side of the auxiliary block, a groove is formed on the side wall of the through groove, and a round rod is fixedly connected to the outer side of the auxiliary block.

[0012] Preferably, the auxiliary block is slidably engaged with the slot, the through groove is connected to the slot opening, the through groove is also connected to the circular groove, the circular rod is located on the outside of the operating table, and the circular rod is slidably connected to the collar.

[0013] Preferably, the fixing component includes a limiting rod that passes through the inside of the circular groove, one end of the limiting rod is fixedly connected to a handle, and the other end of the limiting rod is fixedly connected to a locking block on its outer surface.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] This invention solves the problem of unstable clamping of the workpiece by winding a rope around its upper end and determining the required distance for the circular rod based on the distance the collar hangs down. Pulling the circular rod moves the auxiliary block along the vertical groove. After moving the auxiliary block to the appropriate position, it is moved laterally to engage with the slot, aligning the through groove with the circular groove. Then, pushing the handle separates the clamping block from the groove and allows it to enter the annular groove through the limiting groove. Rotating the handle causes the clamping block to rotate along the annular groove, separating it from the limiting groove. The limiting rod prevents accidental separation of the auxiliary block from the groove. The collar in the taut rope is then placed onto the exposed circular rod to clamp and position the upper end of the workpiece, facilitating subsequent surface treatment and solving the problem of unstable clamping of the workpiece from all sides.

The circular groove 221 is a positioning groove for the circular rod 2312 at different heights. The slot 2221 is the corresponding groove of the circular groove 221. The slot 2221 is used to place the auxiliary block 231. The vertical groove 222 facilitates the up and down sliding of the auxiliary block 231.
