Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sleeves, and in particular relates to a collision-proof lathe safety sleeve. Background Art
[0002] When processing on a lathe, each time after clamping a part, the lathe handle needs to be used to tighten the three jaws to drive the three jaws to clamp the part and complete the fixation of the part. Most existing wrenches have short lever arms. When the chuck is large or the part size is large, the torque is not enough when manually tightening the lathe handle, and a sleeve needs to be used to increase the torque on the lathe handle.
[0003] The lathe handle is a bare rod. Since the lathe handle and the sleeve are not an integrated structure, workers often slip when tightening the sleeve. After the sleeve slips, it will slide rapidly, causing the hand to be squeezed. Utility Model Content
[0004] In order to solve the problem of squeezing the hand after the sleeve slips on the handle in the prior art, the utility model provides a safety sleeve for lathe workers that prevents collision. The adjustment mechanism in the utility model can adjust the maximum length of the handle inserted into the sleeve body, thereby leaving a safe distance for the hand on the handle to prevent the hand from being injured when the sleeve body slides; at the same time, the buffer mechanism is set to further protect the hand when the sleeve body slides to prevent the hand from being injured.
[0005] The technical solution adopted by the anti-collision lathe safety sleeve of the utility model is:
[0006] The utility model provides a collision-proof lathe safety socket, comprising a socket head, the socket head being connected to a handle, and the handle being perpendicular to the socket head, and also comprising a socket body matched with the handle, the handle being insertable into the socket body, and an adjusting mechanism for adjusting the length of the handle inserted into the socket body is arranged at one end of the socket body away from the handle, and a buffer mechanism for protecting the hand is arranged at the other end of the sleeve body.
[0007] In this further technical solution, the maximum length of the handle inserted into the sleeve body can be adjusted by the setting of the adjustment mechanism, so that when the sleeve body slides on the handle, until the adjustment mechanism contacts the handle, the end of the sleeve body away from the adjustment mechanism is still a certain distance from the sleeve head, thereby leaving a safe distance for the hand on the handle, and the hand will not be hurt even if the sleeve body slides; the buffer mechanism can be set to prevent the sleeve body from directly contacting the hand when the safety distance is not enough, and the buffer mechanism is used to buffer the sleeve body and the hand to prevent the hand from being directly squeezed by the sleeve body.
[0008] Furthermore, one end of the sleeve body provided with the buffer mechanism is provided with a connecting ring, the outer wall of the connecting ring is provided with a first external thread, and the inner wall of the other end of the sleeve body is provided with an internal thread matching the first external thread.
[0009] In this further technical solution, when the torque provided by one sleeve body is insufficient, multiple sleeve bodies can be connected together through the cooperation of the first external thread and the internal thread, thereby providing appropriate torque.
[0010] Furthermore, the adjustment mechanism includes a blocking block for blocking one end of the sleeve body, a connecting block extending into the sleeve body is provided on one side of the blocking block, and a lifting ring is provided on the other side of the connecting block; wherein, the side wall of the connecting block is provided with a second external thread matching the internal thread.
[0011] In this further technical solution, the connecting block and the sleeve body can be connected together through the mutual cooperation of the second external thread and the internal thread, and the length of the connecting block in the sleeve body can be adjusted by rotating the blocking block, thereby adjusting the maximum length of the handle inserted into the sleeve body.
[0012] Furthermore, the buffer mechanism includes a rubber plug inserted into the connecting ring, a through hole for convenient insertion of the handle is provided at the center of the rubber plug, and a protrusion is provided at the edge of the rubber plug.
[0013] In this further technical solution, a rubber plug is provided to prevent the sleeve body from directly contacting the hand when the safety distance is not enough. A buffer mechanism is used between the sleeve body and the hand to prevent the hand from being directly squeezed by the sleeve body. The protrusion is provided to facilitate the insertion or removal of the rubber plug from the sleeve body.
[0014] Furthermore, a warning area is provided on the outer wall of the sleeve body between the adjusting mechanism and the buffer mechanism, and the warning area is coated with warning paint.
[0015] In this further technical solution, by providing warning paint, when the sleeve body slides, the operator can find it in time and release the force in time.
[0016] Furthermore, a friction area is provided in the warning area for easy hand holding.
[0017] In this further technical solution, the frictional force between the operator's hand and the sleeve body can be increased by setting the friction zone, thereby facilitating use.

[0028] refer to Figure 1 and Figure 2 It can be known that in the present invention, a connecting ring 6 is fixedly connected to one end of the sleeve body 3 close to the sleeve head 1 , and a first external thread 7 is provided on the outer wall of the connecting ring 6 .
[0029] In the present invention, the sleeve body 3 can be referred to in the specific configuration. Figure 3 ,according to Figure 3 It can be seen that an inner wall of the sleeve body 3 is provided with an inner thread 8 matching with the first outer thread 7 at one end away from the connecting ring 6 .
[0030] The adjustment mechanism 4 in the utility model can be referred to in the specific arrangement Figure 2 ,according to Figure 2 It can be seen that the adjustment mechanism 4 includes a blocking block 9 for blocking one end of the sleeve body 3, one side of the blocking block 9 is fixedly connected to a connecting block 10 for extending into the sleeve body 3, the side wall of the connecting block 10 is provided with a second external thread 12 matching the internal thread 8, and the other side of the blocking block 9 is fixedly connected to a hanging ring 11, so that the sleeve body 3 can be conveniently hung in a suitable position when the sleeve body 3 is not in use.
[0031] The buffer mechanism 5 in the utility model can be further referred to when specifically setting it. Figure 2 ,according to Figure 2 It can be seen that the buffer mechanism 5 includes a rubber plug 13 inserted into the connecting ring 6, a through hole 14 is provided at the center of the rubber plug 13 for convenient insertion of the handle 2, and an annular protrusion 15 is fixedly connected to the edge of the rubber plug 13. In the utility model, the rubber plug 13 and the protrusion 15 are both made of rubber material.
[0032] Continue to refer Figure 1 and Figure 2 A warning area 16 is provided on the side wall of the sleeve body 3 between the adjusting mechanism 4 and the buffer mechanism 5, and the warning area 16 is coated with yellow and black warning paint; at the same time, a friction area 17 is provided in the warning area 16, and the friction area 17 is provided with knurling processed by a knurling cutter, and the knurling is ground.
[0033] The working principle of the anti-collision lathe safety sleeve is as follows: when the utility model is used, the bottom of the sleeve head 1 is first inserted into the machine tool chuck, and then the operator holds the handle 2 and the top of the sleeve head 1 with one hand at the same time, and applies a force toward the machine tool chuck to the sleeve head 1, thereby preventing the sleeve head 1 from being separated from the machine tool chuck; then the operator holds the handle 2 away from the end of the handle 2 with the other hand and rotates it, thereby rotating the sleeve head 1, so that the three-claw clamps the parts on the machine tool chuck.
[0034] When the torque provided by the handle 2 is insufficient to rotate the socket head 1 , the socket body 3 can be inserted into the handle 2 to extend the torque of the handle 2 through the socket body 3 , thereby rotating the socket head 1 .
[0035] Before using the sleeve body 3, the second external thread 12 and the internal thread 8 cooperate with each other to connect the connecting block 10 to the sleeve body 3, and by rotating the blocking block 9, the length of the connecting block 10 in the sleeve body 3 can be adjusted, thereby adjusting the maximum length of the handle 2 inserted into the sleeve body 3. When the sleeve body 3 slides on the handle 2, until the adjusting mechanism 4 contacts the handle 2, the end of the sleeve body 3 away from the adjusting mechanism 4 is still a certain distance away from the sleeve head 1, thereby leaving a safe distance for the hand on the handle 2, and the hand will not be hurt even if the sleeve body 3 slides.
[0036] At the same time, the buffer mechanism 5 in the utility model can prevent the sleeve body 3 from directly contacting the hand when the safety distance is not enough. The buffer mechanism 5 provides buffering between the sleeve body 3 and the hand to prevent the hand from being directly squeezed by the sleeve body 3, thereby further protecting the hand.
[0037] When the sleeve body 3 of the utility model is in use, the warning paint provided can facilitate the operator to promptly discover when the sleeve body 3 slides and to release the force in time; the friction zone 17 provided can increase the friction between the operator's hand and the sleeve body 3, thereby facilitating use.
[0038] At the same time, when the torque provided by one sleeve body 3 is insufficient, multiple sleeve bodies 3 can be connected together through the cooperation between the first external thread 7 and the internal thread 8 to provide appropriate torque.
[0039] In the above embodiment, the utility model provides a collision-proof lathe safety socket. The utility model can adjust the maximum length of the handle inserted into the socket body through the adjustment mechanism, so that when the socket body slides on the handle, until the adjustment mechanism contacts the handle, the end of the socket body away from the adjustment mechanism is still a certain distance from the socket head, thereby leaving a safe distance for the hand on the handle, and the hand will not be hurt even if the sleeve body slides; the buffer mechanism can prevent the sleeve body from directly contacting the hand when the safety distance is not enough, and the buffer mechanism is used to buffer the sleeve body and the hand to prevent the hand from being directly squeezed by the sleeve body.
