Abstract
The invention relates to a safety protection device for a long handle pneumatic screwdriver. A protective sleeve (3) is arranged outside the long handle pneumatic screwdriver, an internal hexahedron is arranged at the rear end of the protective sleeve and matched with an external hexahedron arranged of a screwdriver handle (4), so that axial movement of the screwdriver handle in the protective handle does not exist, an internal circular shape is arranged on a position where the front end of the protective sleeve (3) exceeds a screwdriver in length, the internal diameter of the internal circular shape equals to the external diameter of a screw (7), and the internal circular shape is sleeved on the screw. When the safety protection device is used for assembling a long handle screw, due to the fact that the protective sleeve is matched with the screw, the screwdriver can not slip off, on one hand, the safety of operators is protected, and on the other hand, production efficiency is further improved. The safety protection device for the long handle pneumatic screwdriver is reasonable in structural design, simple in manufacturing, and capable of improving work efficiency, eliminating potential safety hazards, improving product quality and reducing production cost, and wide in application range and favorable for popularization and application.
Description
Technical field
The present invention relates to the safe precaution measure field of pneumatic tool when actual job, particularly a kind of safety guard that is used for the long handle pneumatic screw driver.
Background technology
Development along with industrialized production; Handwork is gradually by mechanization; Institute of Automation substitutes, and is especially electronic, the application of pneumatic tool in our activity in production is more extensive, is example with the pneumatic impact spanner; A workman thousand screws of will screwing on every day in the assembly shop of enterprise, pneumatic impact spanner is the operating efficiency that this simple repeated operation has promoted several times.But because driver bit and screw concave surface need fit like a glove; During assembling, driver bit is put into screw recess, screw is rotated through the rotation screw cutter; Because of using the electric screw driver velocity of rotation very fast; Coping screw is long again, and screw head takes place centrifugally during rotation, security incident takes place thereby driver bit will skid off the screw concave surface or need again to lower efficiency greatly driver bit and screw concave surface are identical again.Therefore, we emphatically research how to prevent that driver bit from skidding off the problem of screw concave surface, thereby when promoting production efficiency, potential safety hazard is reduced to " 0 "
Summary of the invention
The object of the invention mainly is can satisfy the high efficiency mode of production in order to provide a kind of, can prevent the pneumatize tool attachments of security incident simultaneously again.And in real work and application modes each parts.
Technical scheme of the present invention is following:
A kind of safety guard that is used for the long handle pneumatic screw driver; Be to be outside equipped with protective sleeve (3) at the long handle pneumatic screw driver, protective sleeve (3) rear end is inner hexahedron, and is identical with the outer hexahedron of screwdriver (4) handle; Reaching screwdriver (4) handle moves axially in protective sleeve (3) nothing; The length place that protective sleeve (3) front end surpasses screwdriver is set to interior circle, and its diameter equals the external diameter of screw (7), is enclosed within on the screw.
Described protective sleeve (3) is considered from safety and economic angle, is 6～8 millimeters with the length L 2 that surpasses screwdriver.
The position L1 size that screwdriver handle (4) distance protection cover (3) is terminal is not collided with protective sleeve (3) and pneumatic impact spanner and to be advisable.
This device is made up of protective sleeve and screwdriver, and outer six sides of screwdriver and interior six sides of protective sleeve closely cooperate, and can not rotate, and can not move axially.When using this device assembling long handle screw, because cooperating of protective sleeve and screw arranged, make the impossible slippage of screwdriver, he has protected operator's safety on the one hand, has improved production efficiency on the other hand again.Reasonable in design of the present invention is made simply, can enhance productivity, and eliminates hidden danger, improves the quality of products, and reduces production costs, and is applied widely, easy to utilize.
Description of drawings
Fig. 1 is the structural representation of apparatus of the present invention;
Fig. 2 is the application example sketch map of this device.
The specific embodiment
Below will combine accompanying drawing that further explain is done in practical implementation of the present invention:
A kind of safety guard that is used for the long handle pneumatic screw driver as shown in Figure 1; Be outside equipped with protective sleeve (3) at the long handle pneumatic screw driver, protective sleeve (3) rear end is inner hexahedron, and is identical with the outer hexahedron of screwdriver (4) handle; Reaching screwdriver (4) handle moves axially in protective sleeve (3) nothing; The length place that protective sleeve (3) front end surpasses screwdriver is set to interior circle, and its diameter equals the external diameter of screw (7), is enclosed within on the screw.Protective sleeve (3) is considered from safety and economic angle.
The outer hexahedron of the interior hexagonal hole of protective sleeve and screwdriver is close to and is connected, and makes not have between them to rotate, and does not also have to move axially.With reference to Fig. 2, an end of protective sleeve (3) is provided with the hole (1) that equates with screw (7) external diameter; One end convex (2) of screwdriver (4) is complementary with the spill of screw (7) end, is 6～8 millimeters with the length L 2 that surpasses screwdriver wherein.The position L1 size that screwdriver (4) handle distance protection cover (3) is terminal is not collided with protective sleeve (3) and pneumatic impact spanner and to be advisable.The outer hexahedron of the other end of screwdriver (4) is used for linking to each other with pneumatic torque spanner, utilizes ball recess and pneumatic torque spanner on the screwdriver (4) to fix, and is convenient to change screwdriver.In the time need screw (7) being screwed in the screw thread of workpiece (6); The convex (2) of screwdriver (4) is contacted with the spill of screw (7); Open pneumatic torque spanner; Because the protection in the hole (1) in the protective sleeve (3) is arranged, the convex (2) of screwdriver (4) can be because of the slippage that overexerts with the spill of screw (7), and moment just can be in place screw-driving.In the practicality, when promoting production efficiency, potential safety hazard is reduced to " 0 ".
Claims (3)
1. safety guard that is used for the long handle pneumatic screw driver; It is characterized in that being outside equipped with protective sleeve 3 at the long handle pneumatic screw driver; Protective sleeve 3 rear ends are inner hexahedron, and are identical with the outer hexahedron of screwdriver handle 4, reach screwdriver 4 handles and move axially in protective sleeve 3 nothings; The length place that protective sleeve 3 front ends surpass screwdriver is set to interior circle, and diameter equals the external diameter of screw 7, is enclosed within on the screw.
2. protective device as claimed in claim 1 is characterized in that the length L 2 that described protective sleeve 3 surpasses screwdriver is 6～8 millimeters.
