Abstract

The utility model discloses a center frame for quickly clamping a workpiece, which consists of a panel, an upper support, a slider, an upper bearing, an upper shaft, lower bearings, lower shafts and a lower support. The upper bearing is fixed on the slider through the upper shaft; the lower bearings are respectively fixed in two grooves in the lower support through the lower shafts; an air cylinder is fixed on the panel; an air intake pipe is connected to the outer side of the air cylinder; and a piston rod in the air cylinder is connected with the slider. When the center frame for quickly clamping the workpiece is used, the piston rod is in a jacking state through air pressure, so that the slider and the upper bearing move downwards to be in a work state, further, the time and labour are saved, the operation is simple and convenient, the cost is low and the efficiency is high; in addition, the concentricity of the positioning outer diameter and the processing part can be ensured to be within the range of 0.02, and the application range is wide; and in addition, the center frame is applied to various types of machine tools, such as general lathes, numeric control lathes, meter lathes, and the like, and the functions of the lathes are finally improved.

Description

A kind of quick-clamping workpiece centre frame
Technical field
The utility model relates to a kind of quick-clamping workpiece centre frame.
Background technology
A kind of annex of centre frame during as the machine tooling workpiece, it mainly acts on is to guarantee working position and a certain external diameter concentricity≤0.02, owing to possess this special function, centre frame has obtained general application in machining industry.But there is a fatal weakness in traditional centre frame, and that is exactly a manual action, and clamping bothers at that rate, and efficient is very low, and accuracy is not high, and application is narrow.
The utility model content
The utility model provides a kind of quick-clamping workpiece centre frame to deficiency of the prior art, and this quick-clamping workpiece centre frame can be installed to according to the characteristics of each enterprise oneself on the various lathes; Such as Digit Control Machine Tool, watchmaker's machine tool, fields such as general car; Can solve most concentricity problem; And this quick-clamping workpiece centre frame clamping speed is fast, easy to operate, has thoroughly solved the problem of traditional centre frame inefficiency.
In order to solve the problems of the technologies described above, the utility model is able to solve through following technical proposals:
A kind of quick-clamping workpiece centre frame, by panel, upper bracket, slide block; Upper bearing (metal), last axle, lower bearing, lower shaft; Lower carriage is formed, and said upper bearing (metal) is fastened on the slide block through last axle, and said lower bearing is separately fixed in two grooves on the lower carriage through lower shaft; Be installed with cylinder on the said panel, the said cylinder outside is connected with air inlet pipe, and piston rod and slide block in the said cylinder link together.
In the technique scheme, two grooves on the said lower carriage are waist type groove.
Beneficial effect: the utility model compared with prior art has following beneficial effect:
The utility model quick-clamping workpiece centre frame in use, air pressure is in the state of ejecting with piston rod, and slide block and upper bearing (metal) are moved down and in running order, thereby time saving and energy saving, simple to operation, cost is low, efficient is high; Secondly, the concentricity that can guarantee to locate external diameter and working position is in 0.02, and is and applied widely, applicable to being installed in all kinds of lathes such as engine lathe, numerically controlled lathe, instrument lathe, finally improves the function of lathe.
Description of drawings
Fig. 1 is the front view of quick-mounting folder workpiece centre frame.
Fig. 2 is the left view of quick-mounting folder workpiece centre frame.
Fig. 3 is the fundamental diagram of quick-mounting folder workpiece centre frame.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
Referring to Fig. 1-3, a kind of quick-clamping workpiece centre frame, by panel 2, upper bracket 3; Slide block 4, upper bearing (metal) 5, last axle 6; Lower bearing 7a, 7b, lower shaft 8a, 8b, lower carriage 9 is formed; Said upper bearing (metal) 5 is fastened on the slide block 4 through last axle 6, and said lower bearing 7a, 7b are separately fixed in two groove 9a on the lower carriage 9, the 9b through lower shaft 8a, 8b, and lower carriage 9 is fastened on the main frame 10.
Be installed with cylinder 1 on the said panel 2, said cylinder 1 outside is connected with tracheae 1a and 1b, and piston rod 1c and slide block 4 in the said cylinder 1 link together.
Two groove 9a on the said lower carriage 9,9b are waist type groove; The benefit of doing like this is the spacing through lower shaft 8a, 8b among direct adjusting waist type groove 9a, the 9b; Thereby regulated the spacing of lower bearing 7a, 7b indirectly, the final workpiece that satisfies the processing different size makes the range of application wider.
During work, workpiece one end is clipped in the machine tool chuck 11, the operative employee is through controlling floor push; Make tracheae 1a air inlet, at this moment the piston thick stick 1c in the cylinder 1 is in the state of ejecting, and moves down with upper bearing (metal) 5 thereby drive slide block 4; This moment, upper bearing (metal) was in running order; Workpiece external diameter (being called the location external diameter) is positioned in the center of upper bearing (metal) 5 and lower bearing 7a, 7b, starts the workpiece rotation motor then, and the other end of workpiece will be in the centre of location rotation of upper bearing (metal) 5 and lower bearing 7a, 7b; At this moment cutting tool 12 can begin machining workpieces, and the workpiece external diameter after cut is accomplished and the concentricity of workpiece external diameter can guarantee in 0.02.When the operative employee unclamps floor push, tracheae 1b air inlet, 1a exhaust; Piston thick stick 1c in the cylinder 1 is in the state of returning; Move up with upper bearing (metal) 5 thereby drive slide block 4, this moment, upper bearing (metal) 5 was in releasing orientation, got into next process thereby at this moment can pull down workpiece easily.
The utility model quick-clamping workpiece centre frame in use, air pressure is in the state of ejecting with piston rod, and slide block and upper bearing (metal) are moved down and in running order, thereby time saving and energy saving, simple to operation, cost is low, efficient is high; Secondly, the concentricity that can guarantee to locate external diameter and working position is in 0.02, and is and applied widely, applicable to being installed in all kinds of lathes such as engine lathe, numerically controlled lathe, instrument lathe, finally improves the function of lathe.
