Abstract
The utility model discloses a handle limit mechanism for a pulley propelling plant of a pipe cutter. The handle limit mechanism comprises a handle support seat fixedly arranged on a rack of the pipe cutter, wherein a waist hole is arranged in the handle support seat, and a handle penetrates in the waist hole. The handle penetrates in the waist hole of the handle support seat, therefore the handle can be prevented from rotating and the travel of the handle can be controlled; and the moving range of the handle is limited in the length range of the waist hole, thus the operation is facilitated, and the phenomenon that the pipe is not cut off or is cut too much can not be caused.
Description
Technical field
The utility model relates to the pipe cutter that a kind of cutting pipe is used, particularly a kind of handle limiting mechanism for pipe cutter pulley propulsion plant.
Background technology
Riser is a vitals that forms in the diffusion absorption type refrigeration system, riser clamping for the ease of pipe before bend pipe must reserve a segment length for clamping, after finishing, must remove redundance again bend pipe, and the riser shape matching that bends is special, be difficult to cutting with common method, and must guarantee that when cutting off outer tube inner tube is injury-free, such cutting machine can not be used for cutting, otherwise inner and outer pipes has been cut off together, unique can use be with cutter slowly rotating of a circle circle cut, but the efficient all too is low like this, can not satisfy the needs of processing far away.
Just extremely be necessary with the pipe cutter of raising the efficiency so research and develop a kind of automatically pipe cutting, but in R﹠D process, each parts, link need well-designed, all linked with one another to realize final purpose.
Preliminary imagination is in the pipe cutter frame one main shaft that rotates to be set, end at main shaft is fixed with swivelling tool-holder, swivelling tool-holder one side is provided with feed control pulley, feed control pulley and main shaft are slidingly socketed, swivelling tool-holder is the hollow circular disk body, be arranged with two pipe cutting cuttves at swivelling tool-holder, leave the gap that holds pipe between two pipe cutting cuttves, the pipe cutting cutter is connected with wedge, wedge is along the setting of main shaft axial direction, be provided with spring between wedge and the main shaft, feed control pulley inside is provided with the conical surface, and feed control pulley inserts in the swivelling tool-holder and makes the conical surface contact cooperation with wedge.
Feed control pulley is connected with the pulley propulsion plant, advance with propelling sheave, described pulley propulsion plant comprises the propelling circle, advance the circle front end to be connected with handle, advance the circle rear end and advance the circle holder hinged, advance snare on the cannelure at feed control pulley middle part, advancing circle to be provided with two through holes in two ends up and down, be equipped with bolt in the through hole, at the bolt cover wearing-proof bearing, wearing-proof bearing and cannelure sidewall contact arranged.Thus, can realize by operating grip, advance circle to stir feed control pulley, along with going deep into of feed control pulley, the conical surface presses down wedge and then drop-down pipe cutting cutter, the cylindrical undercutting that the pipe cutting cutter is hauled to pipe is gone, along with the slowly propelling of handle, the pipe cutting cutter cuts darker and darker on tube wall until pipe is cut off.
Find through practice, handle has the trend of rotation under the effect of wedge and pulley frictional force, so need firmly that it is firmly stable, moreover the stroke of handle and workman's experience have much relations, mainly be by the people feel operate, if the words of neophyty operation, might produce and not cut off or cut excessive result, so, still remain to be improved.
The utility model content
The utility model has overcome above-mentioned the deficiencies in the prior art, a kind of handle limiting mechanism that handle is controlled be convenient to is provided, and this position-limit mechanism is the important component part of pipe cutter, one can joystick stroke, two can prevent that handle from rotating, and save muscle power.
The technical solution of the utility model is achieved in that
Be used for the handle limiting mechanism of pipe cutter pulley propulsion plant, comprise the handle supporting seat that is fixedly installed on the pipe cutter frame, be provided with slot at the handle supporting seat, handle is located in the slot.
As preferably, handle is connected with reset tension spring, an end connecting handle of reset tension spring, the other end connecting handle supporting seat of reset tension spring.
Adopted principle of the present utility model and the beneficial effect of technique scheme to be:
The utility model is located in handle in the slot of handle supporting seat, one can prevent that handle from rotating, and two can the joystick stroke, and the moving range of handle is limited in the length range of slot, thereby be beneficial to operation, can not produce and not cut off or cut excessive phenomenon.
In addition, handle also is connected with back-moving spring, so that handle can reset, so that more convenient to operate.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The specific embodiment of the present utility model is as follows:
Embodiment: as shown in Figure 1, a kind of handle limiting mechanism for pipe cutter pulley propulsion plant comprises the handle supporting seat 25 that is fixedly installed on the pipe cutter frame, is provided with slot 26 at handle supporting seat 25, and handle 21 is located in the slot 26.
Reset for the ease of handle, handle 21 is connected with reset tension spring 27, an end connecting handle 21 of reset tension spring 27, the other end connecting handle supporting seat 25 of reset tension spring 27.
Claims (2)
1. be used for the handle limiting mechanism of pipe cutter pulley propulsion plant, it is characterized in that: comprise the handle supporting seat that is fixedly installed on the pipe cutter frame, be provided with slot at the handle supporting seat, handle is located in the slot.
2. the handle limiting mechanism for pipe cutter pulley propulsion plant according to claim 1 is characterized in that, handle is connected with reset tension spring, an end connecting handle of reset tension spring, the other end connecting handle supporting seat of reset tension spring.
