Description

Technical Field

[0001] The invention relates to the field of tool clamps, in particular to a heat shrinkable tube clamp rapid cooling device. Background Art

[0002] Heat shrink collet is a commonly used tool clamp, which uses the principle of thermal expansion and contraction of materials to clamp the tool. Since the thermal expansion coefficient of the heat shrink collet is higher than that of the tool, the tool can be placed in the hole of the heat shrink collet at high temperature, and the tool can be clamped after cooling. Currently, there are only special ones on the market, which are inconvenient to operate and relatively expensive. This device is easy to operate, cost-effective, and does not damage the heat shrink collet and the tool. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a heat shrink tube clamp rapid cooling device, which is simple to use, can meet the needs of rapid cooling of the heat shrink tube clamp, and has a relatively low use cost.

[0004] The technical solution adopted by the present invention to solve its technical problems is: to provide a heat shrink tube clamp rapid cooling device, including a tube shell and a base installed at the lower end of the tube shell, the inner center of the tube shell is vertically arranged with a center column whose lower end is connected to the base, the upper end of the center column is axially connected with the heat shrink tube clamp, the interior of the tube shell is provided with a cooling sleeve coaxially sleeved on the outer side of the center column, one side of the base is provided with an air inlet hole, compressed air is passed into the air inlet hole to push the cooling sleeve to slide axially, and at least one cooling air hole is provided at the bottom of the cooling sleeve, and the cooling air hole is connected to the central hole cavity of the cooling sleeve.

[0005] The function of the center column is to support the heat shrink tube clamp. The maximum diameter of the heat shrink tube clamp should be smaller than the center hole diameter of the cooling sleeve, so that the cooling sleeve can cover the heat shrink tube clamp.

[0006] The external compressed air enters the bottom of the tube shell from the air inlet hole and rushes upward, which can lift the cooling sleeve until the heat shrink tube clamp is covered. At the same time, the compressed air enters from the cooling air hole and passes into the central hole cavity to cool the heat shrink tube clamp, taking away the heat of the heat shrink tube clamp and discharging it from the upper end of the cooling sleeve, thereby realizing rapid cooling of the heat shrink tube clamp.

[0007] Preferably, the lower end of the cooling sleeve is connected to a guide seat, and the guide seat is provided with air holes corresponding to the cooling air holes. The guide seat has a guiding function, and can make the rising of the cooling sleeve more stable.

[0008] Preferably, screw holes are arranged on the guide seat along the circumferential direction, and screws connected to the center column are arranged in the screw holes to facilitate the installation of the guide seat.

[0009] Preferably, the outer wall diameter of the guide seat matches the diameter of the upper opening of the cylinder shell, and friction is used to buffer the guide seat in the final stage of its rapid rise. A circle of limiting steps is provided at the bottom of the outer wall of the guide seat to serve as a stop and limit.

[0010] Preferably, a circle of air intake ring grooves is arranged at the upper end of the base, and the air intake ring grooves are connected with the air intake holes, so that the air intake ring grooves can evenly pass the compressed gas entering through the air intake holes into the cylinder shell.

[0011] Furthermore, there are three cooling air holes which are evenly arranged around the circumference, so that the area of ​​the heat shrinkable tube clamp blown by the compressed air is relatively large, so that the cooling is more uniform.

[0012] At the same time, the cooling air holes are connected to the central bore of the cooling sleeve through a plurality of transverse connecting holes, so that compressed gas can be blown to each axial position of the heat shrinkable tube clamp.

[0013] Furthermore, a plurality of annular grooves are provided on the side wall of the central bore of the cooling sleeve, and the annular grooves can slow down the flow rate of the compressed gas in the central bore of the cooling sleeve, prolong the residence time, and improve the cooling efficiency.

[0014] Beneficial effects: The present invention relates to a heat shrink tube clamp rapid cooling device, which has a unique structure and is easy to use. It can meet the needs of rapid cooling of the heat shrink tube clamp, has a relatively low cost of use, and the compressed air source is relatively easy to find in the workshop, and has a good promotion value.
