As a further technical scheme, the extending part is in threaded connection with the shell to realize detachable connection of the lantern ring and the shell.
As a further technical scheme, the end face of the shell and the blocking part are in screw connection to realize detachable connection of the lantern ring and the shell.
As a further technical scheme, at least two guide keys are arranged between the sleeve and the shell.
As a further technical scheme, the screw rod further comprises a screw rod, one end of the screw rod is arranged on the end face of the shell through a stop block and a fastening stop block, and the other end of the screw rod is connected with the internal threads of the sleeve.
As a further technical scheme, the shell is provided with a flange plate mounting base for being mounted on the chuck base.
In a second aspect, the present utility model provides a chuck comprising a chuck base and a plurality of circumferentially uniformly arranged vertical lathe jaws as described in the first aspect.
The beneficial effects of the utility model are as follows:
According to the utility model, as the sleeve ring is detachably connected with the shell, when the sleeve is slightly deformed and the sleeve ring is ground, the sleeve ring can be detached for grinding to realize normal extension of the sleeve. Compared with the process of disassembling the sleeve to carry out small running or polishing, the maintenance process is quicker only by disassembling the sleeve ring, and the subsequent alignment process of the sleeve is omitted.
Drawings
The accompanying drawings, which are included to provide a further understanding of the utility model and are incorporated in and constitute a part of this specification, illustrate embodiments of the utility model and together with the description serve to explain the utility model. It should also be understood that the drawings are for simplicity and clarity and have not necessarily been drawn to scale. The utility model will now be described and explained with additional specificity and detail through the use of the accompanying drawings in which:
FIG. 1 shows a top view of a neutral lathe jaw in accordance with an embodiment of the present utility model;
Fig. 2 shows a top view of a jaw of a vertical lathe of the prior art.
In the figure: 1. a screw rod; 2. a housing; 3. a sleeve; 4. a guide key; 5. a stop block; 6. fastening a stop block; 7. a flange plate mounting base; 8. a collar.
Detailed Description
The technical solutions in the exemplary embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.
Example 1
As shown in fig. 1, the present embodiment provides a vertical lathe jaw including a housing 2 and a sleeve 3. The two ends of the shell 2 are opened, one end of a screw rod 1 included in the vertical lathe claw enters the shell 2 through one port, the port is arranged on the end face of the shell 2 through a stop block 5 and a fastening stop block 6, and the other end of the screw rod 1 is connected with the internal thread of the sleeve 3.
It will be appreciated that the whole screw 1 is not fully threaded, and no threads are provided at the contact points with the housing 2, the stop 5 and the fastening stop 6, and the square head at the end of the screw 1 facilitates screwing by using a tool.
When the screw rod 1 is rotated, the sleeve 3 moves forwards and backwards, and the telescopic clamping effect is achieved.
In the prior art, as shown in fig. 2, the sleeve 3 is in direct contact with the shell 2, and the sleeve 3 is slightly deformed due to long stress time, so that the sleeve 3 is easy to be ground with the shell 2, and the telescopic clamping effect of the sleeve 3 is lost. In order to solve the problem, the sleeve 3 is required to be disassembled for small turning or polished, and the disassembly and maintenance process is complicated.
In this embodiment, a collar 8 is disposed between the housing 2 and the sleeve 3, the collar 8 is sleeved on the sleeve 3 and is in sliding contact with the sleeve 3, and the collar 8 is detachably connected with the housing 2.
Because the lantern ring 8 is detachably connected with the shell 2, when the sleeve 3 slightly deforms and the lantern ring 8 is ground, the sleeve can be normally stretched by grinding through detaching the lantern ring 8. Compared with the process of disassembling the sleeve 8 for small running or polishing, the maintenance process of the embodiment is quicker, and the subsequent alignment process of the sleeve 3 is omitted.
The collar 8 has an L-shaped cross section and has an insertion portion and a blocking portion, the insertion portion being inserted between the sleeve 3 and the housing 2 in sliding contact with the sleeve 3, the blocking portion being fitted to an end face of the housing 2. In this embodiment, the short side of the L-shaped cross section is the protruding portion, and the long side is the blocking portion.
One implementation of the detachable connection of this embodiment is: the detachable connection of the collar 8 with the housing 2 is achieved by the threaded connection of the collar 8 with the housing 2 at the extension. The blocking part is required to be arranged into a polygon in the arrangement mode, so that the tool can be conveniently used for screwing.
Another implementation manner of the detachable connection of this embodiment is: the end face of the shell 2 and the blocking part are connected by screws so as to realize the detachable connection of the lantern ring 8 and the shell 2. The installation mode needs to be provided with a plurality of installation holes which are arranged oppositely on the end face of the shell 2 and the blocking part, the installation holes are uniformly arranged along the circumference, the installation holes which are arranged oppositely are provided with threads, or the installation holes on the end face of the shell 2 are provided with threads, and the detachable connection of the lantern ring 8 is realized by penetrating a screw.
The sleeve 3 locks the rotation direction through the shell 2 and the guide key 4, and when the screw rod 1 is rotated, the forward and backward movement of the sleeve 3 is realized.
The housing 2 is provided with a flange mounting base 7 for mounting on a chuck base. It will be appreciated that the flange mounting base 7 is detachably connected to the chuck base by bolts.
Example two
The embodiment provides a chuck, which comprises a chuck base and a plurality of vertical lathe jaws uniformly distributed along the circumference.
Although the present utility model has been described in terms of the preferred embodiments, it is not intended to be limited to the embodiments, and any person skilled in the art can make any possible variations and modifications to the technical solution of the present utility model by using the methods and technical matters disclosed above without departing from the spirit and scope of the present utility model, so any simple modifications, equivalent variations and modifications to the embodiments described above according to the technical matters of the present utility model are within the scope of the technical matters of the present utility model.
