Description
Technical Field
The invention belongs to the technical field of numerically-controlled machine tool accessories, and particularly relates to a clamping device for turning small parts, which is capable of preventing clamping hands.
Background
The automation degree of the numerical control machine tool is relatively high, and in order to achieve the purpose of rapid clamping, a matched tailstock is usually driven pneumatically or hydraulically. However, the machine tool is not necessarily matched with an automatic feeding mechanism, for example, a simple numerical control lathe of a single plate type uses tailstock ejector pins to clamp a workpiece, an operator is required to hold the workpiece by hand before pushing the workpiece, and the machine tool is not difficult to manually feed parts with larger diameters and slender shaft parts and is safe to operate. If the diameter and the length of the part are relatively smaller, the hand-held part is close to the top part of the part, and once an operator carelessly or fatigues, the operator is easy to take a vicious accident that the finger is clamped, so that loss and injury are caused to companies and individuals. The safety accident happens many times in the past, and workshops also take precautions against the safety accident, but basically the safety accident mainly comprises strengthening training and requires staff to improve the attention, but the safety accident has poor effect, and people have negligence. Therefore, a new clamping scheme aiming at turning small parts needs to be formulated, so that the influence factors of people are reduced, and the safety risk is reduced.
The company is improved against the risk and realizes a certain application, and the two patent documents are described as follows:
The patent document with the patent number of CN207255270U provides a pneumatic tailstock error proofing device, which specifically discloses a pneumatic tailstock error proofing device which is used for stopping the ejection of a pneumatic tailstock and ensuring the safety of operators and the safety of equipment by closing an electromagnetic valve after receiving a signal through a photoelectric switch and blocking gas from entering a tailstock cylinder. In terms of application, the cost of the photoelectric device, particularly the grating, is high, the photoelectric element is easy to deviate from a control point and damage due to the vibration of a machine tool, and the control effect is easy to lose efficacy. The photoelectric element is a wearing part and has high maintenance cost.
The patent document with the patent number of CN108941631A provides a hand clamping prevention lathe motor tailstock, which specifically discloses the hand clamping prevention tailstock which consists of a motor tailstock, a pneumatic control system and a spring center. The step-by-step propping structure is adopted, the ball end of the outer sleeve is firstly contacted with the workpiece, the axial stress of the spring is only 1-2N during initial contact, and the compression amount of the spring is 18-22 mm, and if the ball end of the outer sleeve is pressed to the finger, the finger is also lighter. And secondly, formally pressing the workpiece after the workpiece is initially contacted. From the current application effect, the safety effect of preventing the clamping hand is good. The step clamping device is adopted, so that the time for clamping the workpiece is delayed, and the machining efficiency is affected to a certain extent; meanwhile, the machine tool is reformed at a certain cost, and in addition, the compression spring is compressed continuously and is easy to fail. In a word, the risk of clamping fingers by the ejector pins cannot be fundamentally eradicated by the patent.

The air gun can be clamped on the fixing frame, so that the air gun is convenient to place, the uniformity of the working environment of the clamping device is improved, the on-site operation is convenient, and the operation safety is improved.
Preferably, the air gun is a serpentine metal hose. The air gun is a serpentine metal hose with adjustable shape and moderate rigidity and flexibility; before the workpiece to be processed is replaced each time, the metal hose can be manually bent, and the blowing position and the blowing angle are adjusted, so that the air gun directly blows the workpiece, the control and the adjustment of the blowing direction of the air gun are facilitated, and the optimal effect of initially positioning the workpiece by air flow is achieved.
Preferably, the cylinder comprises a first piston cavity and a second piston cavity which are positioned at two sides of the piston, and when the piston moves towards the first piston cavity, the piston rod moves close to the clamp; the first reversing valve is a two-position four-way manual reversing valve, a working port A of the first reversing valve is communicated with the first piston cavity, a working port B of the first reversing valve is communicated with the second piston cavity, an air inlet T of the first reversing valve is communicated with compressed air, an air outlet P of the first reversing valve is communicated with the atmosphere, and the one-way throttle valve and the second reversing valve are respectively communicated with the working port B of the first reversing valve.
Further, the second reversing valve is a two-position three-way electromagnetic reversing valve, a working port A of the second reversing valve is communicated with the air gun, and an air inlet T of the second reversing valve is communicated with a working port B of the first reversing valve.
The beneficial effects are that: according to the clamping device for turning small parts, which is capable of preventing clamping hands, compressed air is simultaneously divided into two paths through the working port B of the first reversing valve: one path is as follows: the workpiece enters an air gun through a second reversing valve, the air gun is taken up by the right hand at the moment, the workpiece is directly blown by compressed gas, and the left hand is loosened after the workpiece is positioned initially; the other path is as follows: and the piston enters a second piston cavity of the air cylinder through the one-way throttle valve to push the piston to move towards the first piston cavity, and meanwhile, the piston rod drives the thimble to move close to the clamp until the thimble abuts against the workpiece. Because of the effect of the one-way throttle valve, the moving speed of the piston rod is limited, the time for clamping the workpiece by the thimble is delayed by 2-3 seconds compared with the time for directly blowing the workpiece by the air gun, at the moment, the left hand is loosened to separate from the workpiece, the aim of sequential actions of initially positioning the workpiece, and then clamping the workpiece by the thimble after loosening the left hand is fulfilled, and the risk of clamping fingers by the thimble can be thoroughly eliminated; the clamping device is simple in structure, easy to manufacture without modifying a machine tool, low in cost and safe and convenient to use.
