Background technology
In pharmaceutical machine and food packing machine field, the glass bottle has obtained general utilization as a kind of container containing.When the glass bottle was finished the action of different station, one needed anchor clamps elder generation clamping glass bottle.The retained part of traditional anchor clamps is mostly made for metallic material, and it crushes the glass bottle easily when clamping glass bottle.Moreover one is held on the bottle mouth position of glass bottle because of above-mentioned anchor clamps, and the chip that the glass bottle that crushes produces enters from the bottleneck of glass bottle easily, so that quality problems occur after to this glass bottle filling and sealing.
The utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of simple and compact for structure, with low cost, folder bottle convenient, can improve the anchor clamps of glass bottle embedding efficient.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of anchor clamps comprise hold assembly, and the bare terminal of described hold assembly is provided with the grip block of being made by plastics or rubber.
Described hold assembly comprises first jig arm and second jig arm of opening and closing mutually, described first jig arm and second jig arm all are provided with the grip block installation portion in bare terminal, described grip block is installed in the grip block installation portion, is provided with elastic component between described first jig arm and second jig arm.
Described grip block is curved, and the grip block on described first jig arm and second jig arm is oppositely arranged, and surrounds installing port.
Described grip block installation portion is provided with locating dowel pin, and described grip block is provided with the knock hole that cooperates with described locating dowel pin.
Described elastic component is a spring, is equipped with spring pin on described first jig arm and second jig arm, and the two ends of described spring are arranged in respectively on the spring pin.
But be respectively equipped with pitch wheel on described first jig arm and second jig arm, on one that is less than in first jig arm and second jig arm, be formed with swing arm, swing described swing arm and can drive first jig arm and second jig arm is swung synchronously by described pitch wheel.
The described grip block that is made of plastics is the polyformaldehyde grip block.
The described grip block of being made by rubber is the polyurethane grip block.
Compared with prior art, advantage of the present utility model is:
Anchor clamps of the present utility model, bare terminal at hold assembly is provided with the grip block that is made of plastics, and for the metal holder clamping of direct usefulness glass bottle, the grip block that plastics are made is difficult for crushing the glass bottle, and then also can reduce the chip that enters the glass bottle, so can improve glass bottle embedding efficient.Moreover the glass bottle only needs enter and elastic force by elastic component comes clamping glass bottle from the installing port of glass bottle, and is convenient and swift, the degree of automation height.Clamp structure of the present utility model is simply compact, with low cost, and the folder bottle is convenient, easy to utilize.

The specific embodiment
As depicted in figs. 1 and 2, anchor clamps of the present utility model comprise hold assembly 1, the bare terminal of hold assembly 1 is provided with the grip block 2 that is made of plastics, for guaranteeing folder bottle effect and long service life preferably, the creep properties of making the plastics of grip block 2 should be better, friction factor should be less, and one friction factor should be smaller or equal to 0.4.For the metal holder clamping of direct usefulness glass bottle, the grip block 2 that the used plastics of the utility model are made is difficult for crushing the glass bottle, and then also can reduce the chip that enters the glass bottle, can improve glass bottle embedding efficient.
In the present embodiment, make the plastics of grip block 2 and select polyformaldehyde for use, also can select for use polyurethane rubber to make grip block 2 in addition.Hold assembly 1 comprises first jig arm 4 and second jig arm 5 of opening and closing mutually, first jig arm 4 and second jig arm 5 all are provided with grip block installation portion 3 in bare terminal, grip block installation portion 3 is provided with locating dowel pin 9, grip block 2 is provided with the knock hole that cooperates with locating dowel pin 9, by locating dowel pin 9 and cooperating of knock hole grip block 2 being fixed in grip block installation portion 3, grip block 2 is curved, and the grip block 2 on first jig arm 4 and second jig arm 5 is oppositely arranged, and surrounds installing port 7.Be provided with the elastic component 6 of pressurized or tension between first jig arm 4 and second jig arm 5, elastic component 6 is a spring, is equipped with spring pin 8 on first jig arm 4 and second jig arm 5, and the two ends of spring are arranged in respectively on the spring pin 8.
For ease of anchor clamps clamping glass bottle, but be respectively equipped with pitch wheel 10 on first jig arm 4 and second jig arm 5, on one that is less than in first jig arm 4 and second jig arm 5, be formed with swing arm 11, in the present embodiment, only be provided with swing arm 11 on second jig arm 5, swing swing arm 11 can be swung synchronously by pitch wheel 10 driving first jig arm 4 and second jig arm 5.When opening, installing port 7 the glass bottle for the treatment of clamping can be positioned over installing port 7, meanwhile, elastic component 6 is stretched, after the glass bottle is in place, discharge swing arm 11, make first jig arm 4 and second jig arm 5 return under the elastic force effect of elastic component 6, thereby realize clamping the glass bottle, clamping is convenient and swift, the degree of automation height.Except can be as shown in this embodiment, be located at swing arm 11 on second jig arm 5 beyond, swing arm 11 can also be located on first jig arm 4, perhaps on first jig arm 4 and second jig arm 5, swing arm 11 is set all.Clamp structure of the present utility model is simply compact, with low cost, and the folder bottle is convenient, easy to utilize.
The above only is a preferred implementation of the present utility model, and protection domain of the present utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.Should propose, for those skilled in the art, in the improvements and modifications that do not break away under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
