Abstract
The utility model discloses a screw locking device of a fuel pump assembly line. The screw locking device of the fuel pump assembly line is provided with a supporting balance fixing frame, the upper end of the supporting balance fixing frame is provided with a three-phrase gear motor, a motor shaft at the lower portion of the three-phrase gear motor is provided with a magnetic powder clutch, a torque sensor, a tension brake and an upper screw sleeve, an air cylinder is arranged at the bottom of the supporting balance fixing frame and is provided with a lower screw sleeve, the lower screw sleeve is fixed through a screw sleeve fixing frame, and an electric control cabinet is arranged on one side of the supporting balance fixing frame. According to the screw locking device of the fuel pump assembly line, screws are fixed at the same time according to the set torsion, the torsion is controlled by the magnetic powder clutch, the torque sensor and the tension brake, the situation that the screws are damaged as being screwed by too large force can be avoided, the situation that the screws are not screwed tightly and oil leakage occurs due to the small force can also be avoided, the screws rotate slowly, rotation vibration does not exist, screw corners cannot be easily damaged by screwing, and due to the close cooperation of the upper screw sleeve, the lower screw sleeve and outer screw corners, threads cannot be easily damaged by screwing, and the quality of the screws are effectively ensured.
Description
Technical field
The utility model relates to a kind of screw locking device, is specifically related to a kind of for being installed in the fuel pump streamline screw locking device that the medium-and-large-sized sealed tube screw on the fuel pump is locked.
Background technology
At present, the existing fuel pump screw locking instrument that is applicable to mainly contains two kinds, gun type electric wrench and hand wrench, the gun type electric wrench torsional forces of wherein being convenient to the fuel pump use is little, at the medium-and-large-sized sealed tube screw of locking, coupling mechanism force is inadequate, being prone to screw does not lock and the problems such as leakage of oil, need to be fastening again by means of the hand wrench, operating efficiency is lower, but the gun type electric wrench is large because of the fast vibration of rotating speed again, and outward appearance and the service life of having rung product are seriously drawn in the outer-hexagonal surface of fragile screw.Use the hand wrench, the artificial muscle power of the slow efficient low cost of speed is large, and it is large that nut is twisted scar, so be badly in need of now addressing the above problem.
Summary of the invention
For the problems referred to above, the purpose of this utility model a kind of laborsaving, high efficiency is proposed and to screw without twisting the fuel pump streamline screw locking device of hindering.
A kind of fuel pump streamline screw locking device, be provided with a balance support fixed mount, described balance support fixed mount upper end is provided with the three-phase reducing motor, and the motor shaft of described three-phase reducing motor bottom is provided with magnetic powder cluth, torque sensor, tension brake and upper swivel nut; Described balance support fixed mount bottom is provided with a cylinder, and described cylinder is provided with swivel nut, and described lower swivel nut is fixed by a swivel nut fixed mount; Described balance support fixed mount one side also is provided with an electric control box.
Also be provided with one in the described tension brake and be used for preventing the spring that screw is impaired.
Described upper swivel nut and lower swivel nut arrange with one heart.
Also be provided with power switch, jettron, motor switch, touch-screen and a plurality of indicator lamp on the described electric control box; Be provided with Programmable Logic Controller in the described electric control box.
Described jettron is electrically connected with cylinder; Described motor switch is electrically connected with the three-phase reducing motor.
A kind of fuel pump streamline of the utility model screw locking device is according to the assembling needs of oil pump product, overcome that production efficiency was low in the past, and the large and screw outer-hexagonal surface of labor intensive muscle power is by problems such as stubborn scar are large, and also has the following advantages:
1, locking torque power is large: adopt phase asynchronous reducing motor and controlled dynamics bidirectional locking anchor clamps;
2, screw and screw be difficult for to be twisted bad: since up and down the good concentricity of swivel nut without swing, lock by axis hole shaft coupling moment of torsion, and can regulate and control the torsional forces size, torsional forces is during greater than the required power of screw, spring can stop in stressed compression revolution, thereby can not twist bad screw;
3, production efficiency is high: can be screwed into simultaneously by two symmetrical screws, as long as symmetrical screw is put into the clamp tool presses starting switch, the several seconds just can finish, than fast upper more than 10 times of previous production efficiency;
4, built-in arrangements for speed regulation: can arrange and be applicable to the needs that the large primary screw of different length is screwed speed.
Description of drawings
Fig. 1 is the overall structure schematic diagram of a kind of fuel pump streamline of the utility model screw locking device.
Fig. 2 is the symmetrical lock screw structural representation of a kind of fuel pump streamline of the utility model screw locking device.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1, structural representation for a kind of fuel pump streamline of the utility model screw locking device, be provided with a balance support fixed mount 1, described balance support fixed mount 1 upper end is provided with three-phase reducing motor 2, and the motor shaft of described three-phase reducing motor 2 bottoms is provided with magnetic powder cluth 3, torque sensor 4, tension brake 5 and upper swivel nut 6; Described balance support fixed mount 1 bottom is provided with a cylinder 7, and described cylinder 7 is provided with swivel nut 8, and described lower swivel nut 8 is fixing by a swivel nut fixed mount 9; Described balance support fixed mount 1 one sides also are provided with an electric control box 10.
Also be provided with power switch 11, jettron 12, motor switch 13, touch-screen 14, a plurality of indicator lamp 15 and Programmable Logic Controller (figure does not look) on the described electric control box 10.
Described jettron 12 is electrically connected with cylinder 7; Described motor switch 13 is electrically connected with three-phase reducing motor 2.
Also be provided with one in the described tension brake 5 and be used for preventing the impaired spring of screw 51.
As depicted in figs. 1 and 2, when using a kind of fuel pump streamline of the utility model screw locking device, at first turn on the power switch 11, then press jettron 12, control cylinder 7 rises, and fixedly treats furbuckles by upper swivel nut 6 and lower swivel nut 8, press motor switch 13, three-phase reducing motor 2 slowly rotates, and screw is slowly screwed in, but just complete operation of several seconds.Simultaneously by the torque magnitude fixed screw of setting, size by magnetic powder cluth 3, torque sensor 4 and tension brake 5 controls, can not twist screw bad because power is excessive, or do not tighten leakage of oil because power is too small, slowly rotate without rotary vibration Luo Jiao and be difficult for twisting wound, add the upper swivel nut 6 of design and closely cooperating of lower swivel nut 8 and outer Luo Jiao, the screw thread of further guaranteeing is difficult for twisting hindering, and has effectively guaranteed the quality of product.
A kind of fuel pump streamline of the utility model screw locking device daily output lock screw is more than 2000, and present existing electric wrench has improved production efficiency greatly in conjunction with about 250 pcs/days of people's output of manual wrench, has reduced production cost.
The utility model is only illustrated explanation with above-described embodiment; the structure of each parts, setting position and connection thereof all can change to some extent; on the basis of technical solutions of the utility model; all improvement and equivalents of individual component being carried out according to the utility model principle all should not got rid of outside protection domain of the present utility model.
