Abstract
The utility model discloses a clamp for quickly replacing a welding pin for polishing. The clamp comprises a clamp main body, a first auxiliary part and a second auxiliary part, wherein a main body slot is arranged in the clamp main body; a small main body slot is arranged under the main body slot; an auxiliary part slot which is in involutory fit with the main body slot is arranged in the first auxiliary part; a small auxiliary part slot which is in involutory fit with the small main body slot is arranged in the second auxiliary part; and the first auxiliary part and the second auxiliary part are respectively and integrally connected with the clamp main body through bolts. The clamp provided by the utility model has the advantages that the welding pin is quickly replaced and the operation is convenient; the welding pin is more efficiently clamped and is prevented from being loosened during a polishing process; and a rotating shaft of a polishing machine is coaxial with the polished welding pin, so that the head of the welding pin after being polished is more smooth.
Description
Technical field
The utility model relates to a kind of anchor clamps, and in particular, the utility model relates to the anchor clamps that a kind of quick replacing capillary is polished.
Background technology
At present, the use of lithium ion electric tool more and more widely, and is well-known, and the advantage little, in light weight with its volume at some field lithium ion battery, that environmental protection can reuse is progressively replacing the leading position of plumbic acid class battery.But single-unit lithium-ion electric core voltage and capacity often do not reach the instructions for use of product, and this just need get up the connection in series-parallel of more piece electricity core, meets the requirements of voltage and capacity.In producing at present normal use be with the shaping nickel strap as conductor, through the resistance-type welding machine it is welded on the both positive and negative polarity of the electric core of many groups.
In existing manufacturing enterprise, mostly a large amount of resistance welders that use are the double-current circulation and have the run-in index welding machine of copper pin soldering tip.The operation principle of this kind resistance welder is: the copper pin of processing through two high-purity brass adds press contacts at nickel strap and electric wicking surface, hangs down time, high current discharge so that said nickel strap moment melts and with firm being sticked together of electric core housing.
This welding manner is widely used in the combinations produce of round battery battery core, for example: when making the lithium ion battery of electric vehicle, need tens round electric cores to go here and there and weld; So the welding frequency of capillary height very; And when welding,, cause the electric conductivity of copper pin to descend because the high temperature that produces that sparks can make a part of nickel strap particle adhere on the copper pin contact; Like this, will increase the possibility that the quick-fried weldering of weldering is leaked greatly.
So, when using the resistance-type welding machine, need behind the certain number of times of welding, polish to the copper pin, be not stained with the nickel strap particle to guarantee copper pin contact.So situation though can guarantee welding quality, can't be increased work efficiency.
The utility model content
The utility model problem to be solved overcomes the defective of above prior art exactly, and the anchor clamps that for this reason provide a kind of quick replacing capillary to polish, to increase work efficiency.
The technical scheme of the utility model is:
The anchor clamps that a kind of quick replacing capillary is polished comprise the jig main body and first auxiliary and second auxiliary; Described jig main body is provided with the main body hole slot, and the below of said main body hole slot is provided with the little hole slot of main body; Said first auxiliary is provided with the auxiliary hole slot that can be involutory with described main body hole slot, and described second auxiliary is provided with the little hole slot of auxiliary that can be involutory with the little hole slot of described main body; Described first, second auxiliary connects as one through bolt and described jig main body respectively.
The diameter of said main body hole slot and said auxiliary hole slot is 10mm, and the degree of depth is 25mm; The diameter of little hole slot of said main body and the little hole slot of auxiliary is 2mm, and the degree of depth is 8mm.
The beneficial effect of the utility model is:
(1) can change capillary fast, easy and simple to handle.
(2) can more effective clamping capillary, guarantee can not become flexible when capillary is polished.
(3) turning cylinder of sander and by the coaxial setting of capillary of being polished can make the capillary syringe needle after the polishing more level and smooth.
Description of drawings
Accompanying drawing is the assembly structure sketch map of the utility model.
The specific embodiment
The anchor clamps that the quick replacing capillary of the utility model is polished are used with sander, belong to the transitional device that connects sander and capillary.For its technical scheme is understood more easily, do to specify below in conjunction with accompanying drawing and embodiment.
With reference to accompanying drawing, the utility model is changed the anchor clamps that capillary is polished fast, comprises the jig main body 2 and first auxiliary 1 and second auxiliary 3; Described jig main body 2 is provided with main body hole slot 22, and the below of said main body hole slot 22 is provided with main body aperture groove 21; Said first auxiliary 1 is provided with the auxiliary hole slot 24 that can be involutory with described main body hole slot 22, and described second auxiliary 3 is provided with the auxiliary aperture groove 23 that can be involutory with described main body aperture groove 21; Described first auxiliary 1 and second auxiliary 3 connect as one through bolt 4 and described jig main body 2 respectively.
The diameter of said main body hole slot 22 and auxiliary hole slot 24 is 10mm, and the degree of depth is 25mm, is used for fixing the turning cylinder that clamps sander.
The diameter of said main body aperture groove 21 and auxiliary aperture groove 23 is 2mm, and the degree of depth is 8mm, is used for fixing the capillary that clamping need be polished.
When using the utility model; Want with bolt 4 to be fixed on the turning cylinder of sander on described first auxiliary 1 described jig main body 2 earlier; Then; The capillary of needs polishing is placed between involutory the main body aperture groove 21 and auxiliary aperture groove 23, is fixedly clamped, begin polishing with described bolt 4; After accomplishing polishing, the bolt 4 of fastening second auxiliary 3 of only need outwarding winding just can take out the good capillary of polishing.
Abovely schematically describe with reference to accompanying drawing with to the utility model, this description does not have restricted.Those of ordinary skill in the art will be understood that in practical application some change all possibly take place the set-up mode of each member in the utility model, and other staff also possibly make similar Design under the enlightenment of the utility model.Only it is pointed out that otherwise break away from the design aim of the utility model that all conspicuous change and similar Design thereof all are included within the protection domain of the utility model.
