Abstract
The invention discloses a clamp with stable transmission, short clamping time and convenient operation, which comprises a base; a fixing seat and a hydraulic cylinder are arranged on the base; a piston rod of the hydraulic cylinder is arranged in the fixing seat in a penetrating and movable way; a sliding base is also arranged on the piston rod; the top of the fixing seat and the top of the sliding base are respectively provided with jaw bodies; the opposite end face of the two jaw bodies form a coordinating jaw. The clamp is generally installed on various machine tools such as a milling machine and is used for clamping objects.
Description
Technical field
The present invention relates to a kind of anchor clamps that are used for the clamping object on the lathe that are installed in.
Background technology
As everyone knows, the anchor clamps of clamping object all are installed on many lathes such as milling machine, its structure generally includes: base, the sliding seat that base is provided with holder and is driven by lead screw transmission mechanism, lead screw transmission mechanism mainly is made of screw mandrel and spanner, the top of holder and the top of sliding seat are respectively arranged with the jaw body, and two jaw bodies cooperatively interact, form jaw.During use, make the sliding seat on the screw mandrel realize moving forward and backward, thereby realize unclamping the purpose with clamping article by the spanner rotary screw rod.The shortcoming of this anchor clamps is: 1, transmission is not steady, causes consistency of product relatively poor, also can make object impaired when serious; 2, the translational speed of screw mandrel is very slow, makes that the time of clamping object is longer, causes production efficiency lower; 3, because sliding seat is that rigidity contacts with the object that needs clamping, wayward its clamping dynamics makes that operation is very inconvenient.
Summary of the invention
Technical problem to be solved by this invention is: a kind of stable drive, clamping time weak point and easy to operate anchor clamps are provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of anchor clamps, comprise: base, base is provided with holder and hydraulic cylinder, the piston rod activity of hydraulic cylinder is located in the holder, also be provided with sliding seat on the piston rod, the top of holder and the top of sliding seat are respectively arranged with the jaw body, and the opposing end surface of two jaw bodies forms the jaw that cooperatively interacts.
Above-mentioned piston rod stretches out holder and fixes with limiting plate.
The invention has the beneficial effects as follows: piston rod is flexible very steady under the guiding of holder among the present invention, and translational speed is very fast, thereby has overcome the not steady and slow-footed shortcoming of clamping of transmission that original screw mandrel transmission causes; In addition, under the driving of hydraulic cylinder, sliding seat contacts for flexible with the object that needs clamping, and its clamping force is controlled easily, and is easy to operate.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Among the figure: 1, base, 2, holder, 3, the jaw body, 4, hydraulic cylinder, 5, piston rod, 6, sliding seat, 7, the jaw body, 8, jaw, 9, limiting plate, 10, bolt.
The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As shown in Figure 1, a kind of anchor clamps of the present invention, comprise: base 1, base 1 is provided with holder 2 and hydraulic cylinder 4, piston rod 5 activities of hydraulic cylinder 4 (being commonly called as oil cylinder) are located in the holder 2, also be provided with sliding seat 6 on the piston rod 5, the opposing end surface that the top of the top of holder 2 and sliding seat 6 is respectively arranged with jaw body 3 and 7, two jaw bodies 3 and 7 forms the jaw 8 that cooperatively interacts.In the present embodiment, stretch out holder 2 and be fixed together at described piston rod 5 by bolt 10 and limiting plate 9.
Piston rod 5 is flexible very steady under the guiding of holder 2 among the present invention, and translational speed is very fast, thereby has overcome the not steady and slow-footed shortcoming of clamping of transmission that original screw mandrel transmission causes; In addition, under the driving of hydraulic cylinder 4, sliding seat 6 contacts for flexible with the object that needs clamping, and its clamping force is controlled easily, and is easy to operate.
Claims (2)
1. anchor clamps, comprise: base, it is characterized in that: described base is provided with holder and hydraulic cylinder, the piston rod activity of hydraulic cylinder is located in the holder, also be provided with sliding seat on the piston rod, the top of holder and the top of sliding seat are respectively arranged with the jaw body, and the opposing end surface of two jaw bodies forms the jaw that cooperatively interacts.
2. anchor clamps as claimed in claim 1 is characterized in that: described piston rod stretches out holder and fixes with limiting plate.
