Utility model content
The utility model object is to provide the clamp of a kind of operating side at zone line.
For reaching above-mentioned purpose, provide following technical scheme:
A kind of clamp, comprises frame and clamp mechanism; Described clamp mechanism comprises left jacking block, left slider, left-hand screw bar, left bevel gear, right jacking block, right slide block, right handed worm, right bevel gear and driving shaft; Described driving shaft is located at the middle part of described frame; Described left-hand screw bar and described right handed worm lay respectively at the left and right sides of described driving shaft; Cooperation bevel gear is installed on described driving shaft; Described left bevel gear is connected with described cooperation bevel gear respectively with described right bevel gear; Described left-hand screw bar is fixedly connected with described left bevel gear; Described right handed worm is fixedly connected with described right bevel gear; Described left jacking block is fixed on described left slider; Described right jacking block is fixed on described right slide block; Described left slider is threaded with described left-hand screw bar, and described left slider moves left and right in described left-hand screw bar; Described right slide block is threaded with described right handed worm, and described right slide block moves left and right in described right handed worm.
As a preferred version, described left-hand screw bar is fixedly connected with by the first pin with described left bevel gear; Described right handed worm is fixedly connected with by the second pin with described right bevel gear.
As another preferred version, the bottom of described left-hand screw bar and the bottom of described right handed worm are provided with pad respectively and between described frame.
As another preferred version, described left jacking block is sleeved on described left slider; Described right jacking block is sleeved on described right slide block.
Compared with prior art, the utility model has the advantage of: described driving shaft is located at the middle part of described frame, operating side is located at middle part of the present utility model.Due to the cooperation that is connected with described cooperation bevel gear of described left bevel gear, the cooperation that is also connected with described cooperation bevel gear of described right bevel gear, so in the time rotating described driving shaft, described driving shaft drives described left bevel gear to rotate together with described right bevel gear.Therefore, described left bevel gear drives respectively described left-hand screw bar to rotate together with described right handed worm with described right bevel gear.Because described left slider is threaded with described left-hand screw bar; Described right slide block is threaded with described right handed worm.Therefore, described left slider moves left and right under the rotarily driving of described left-hand screw bar.Described right slide block also moves left and right under the rotarily driving of described right handed worm.Also driven described left jacking block and described right jacking block to move left and right simultaneously.Therefore completed in the middle of clamp and operated, controlled clamp folding and the action of closing.
The utility model is by the rotation of described driving shaft, and the connection of multiple bevel gear and rotary part drive, and described left jacking block and described right jacking block are moved to middle and both sides, controls clamp folding and the action of closing.And be positioned at the centre of whole clamp as the described driving shaft of operating side, avoided the problems such as cutter interference and operation cannot realize.
Brief description of the drawings
Further illustrate the utility model below in conjunction with the drawings and specific embodiments:
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is plan structure schematic diagram of the present utility model.
Detailed description of the invention
For making technological means of the present utility model, reach object and effect is easy to understand, below in conjunction with detailed description of the invention, further set forth the utility model.
An embodiment of the present utility model is:
A kind of clamp, comprises frame 1 and clamp mechanism.Clamp mechanism comprises left jacking block 2,3 of left cunnings, left-hand screw bar 4, left bevel gear 5, right jacking block 6, right slide block 7, right handed worm 8, right bevel gear 9 and driving shaft 10.Driving shaft 10 is located at the middle part of frame 1; Left-hand screw bar 4 and right handed worm 8 lay respectively at the left and right sides of driving shaft 10.On driving shaft 10, be provided with and coordinate bevel gear 11, left bevel gear 5 is connected with cooperation bevel gear 11, and right bevel gear 9 is also connected with cooperation bevel gear 11.Left-hand screw bar 4 is fixedly connected with by pin with left bevel gear 5, and right handed worm 8 is also fixedly connected with by pin with right bevel gear 9.Left jacking block 2 is sleeved on left slider 3, and right jacking block 6 is sleeved on right slide block 7.Left slider 3 is threaded with left-hand screw bar 4, and left slider 3 moves left and right in left-hand screw bar 4; Right slide block 7 is threaded with right handed worm 8, and right slide block 7 moves left and right in right handed worm 8.Between the bottom of the bottom of left-hand screw bar 4 and right handed worm 8 and frame 1, be respectively equipped with pad 12.
Driving shaft 10 is located at the middle part of frame 1, and operating side is positioned at middle part of the present utility model.Due to left bevel gear 5 with coordinate bevel gear 11 cooperation that is connected, the cooperation that is also connected with cooperation bevel gear 11 of right bevel gear 9, so in the time of rotating driveshaft 10, driving shaft 10 drives left bevel gear 5 to rotate together with right bevel gear 9.Therefore, left bevel gear 5 drives respectively left-hand screw bar 4 to rotate together with right handed worm 8 with right bevel gear 9.Because left slider 3 is threaded with left-hand screw bar 4; Right slide block 7 is threaded with right handed worm 8.Therefore, left slider 3 moves left and right under the rotarily driving of left-hand screw bar 4.Right slide block 7 also moves left and right under the rotarily driving of right handed worm 8.Also driven moving left and right of left jacking block 2 and right jacking block 6, move on Ji Xiang center or both sides simultaneously.Therefore completed in the middle of clamp and operated, controlled clamp folding and the action of closing.
