Description

Technical Field

[0001] The utility model relates to the field of flat-nose pliers, in particular to a pair of dust-proof and liquid-proof flat-nose pliers. Background Art

[0002] At present, the development of the drilling machine processing industry has higher and higher requirements for the control of production and processing precision and cost. In the process of production and processing, different flat-nose pliers will be selected for different scenes and when processing different workpieces. Flat-nose pliers, also known as machine vises, are a universal clamp that is often used to install small workpieces. It is a random accessory of milling machines and drilling machines. It is fixed on the machine tool workbench to clamp the workpiece for cutting processing.

[0003] Flat-nose pliers are usually used to clamp workpieces for cutting processing, but the flat-nose pliers on drilling and milling machines produce a lot of chips after each work. Because lubricating oil needs to be added, the chips are very easy to adhere to the lead screw, and the vacuum cleaner is not easy to handle. This seriously affects the service life of the flat-nose pliers. When existing milling machines and drilling machines are processing workpieces, it is necessary to use the flat-nose pliers on the machine tool to fix the workpiece. After the flat-nose pliers are used to fix the workpiece, the lathe will generate large vibrations when processing the workpiece, so it is easy to cause the screw of the flat-nose pliers to vibrate itself, resulting in the center of mass may not always remain on the rotating shaft, resulting in centrifugal force and vibration rotation, which in turn causes the workpiece to be not firmly fixed, affecting the processing of the workpiece by the lathe. Utility Model Content

[0004] In order to make up for the above deficiencies, the utility model provides a dust-proof and liquid-proof flat-nose pliers, aiming to improve the problem that the existing screw is prone to vibration and rotation when vibrating.

[0005] The utility model is achieved in this way:

[0006] The utility model provides a dustproof and liquid-proof flat-nose pliers, comprising a base plate, a fixed clamping plate is fixed on the outer wall of the upper end of the base plate, a limiting slide rail is arranged on the outer wall of the upper end of the base plate, a movable clamping plate is slidably connected to the inner wall of the limiting slide rail, a contact layer is arranged on the outer walls of the movable clamping plate and the fixed clamping plate, a side plate is fixedly connected to the side wall of the base plate, a threaded rod is rotatably connected to the inner wall of the side plate, an end of the threaded rod is in rotational contact with the outer wall of the movable clamping plate, and a locking mechanism is arranged on the outer wall of the threaded rod.

[0007] Preferably, the locking mechanism comprises a limit gear sleeved on the outer side wall of the threaded rod, and a mounting piece is fixedly connected to the front side of the limit gear.

[0008] Preferably, a locking rod is slidably connected to the inner side wall of the mounting member, and connecting plates are fixedly connected to both sides of the rear end of the locking rod.

[0009] Preferably, a tension spring is fixedly connected to the outer side wall of the connecting plate, and one end of the tension spring away from the connecting plate is fixedly connected to the outer side wall of the mounting member.

[0010] Preferably, the tail portion of the locking rod is fixedly connected to a tail plate, and a pull ring is provided on the outer side wall of the tail plate.

[0011] Preferably, one end of the threaded rod away from the movable clamping plate is fixedly connected to a hand wheel.

[0012] The beneficial effects of the utility model are:

[0013] By setting up the retractable dust cover, when the movable clamp and the fixed clamp are clamping the parts for processing, the cut debris will be blocked by the retractable dust cover and will not adhere to the threaded rod, thereby ensuring the use effect of the threaded rod. By setting up the locking mechanism, the rotation of the threaded rod can be restricted during use, ensuring that the threaded rod will not rotate even if it is subjected to large vibrations, thereby ensuring the fixing effect of the entire flat-nose pliers.

[0021] Example

[0022] Reference Figure 1-4 A dustproof and liquid-proof flat-nose pliers comprises a bottom plate 2, a fixed clamp 201 is fixed on the outer wall of the upper end of the bottom plate 2, a limiting slide rail 203 is arranged on the outer wall of the upper end of the bottom plate 2, a movable clamp 202 is slidably connected to the inner wall of the limiting slide rail 203, and a contact layer 207 is arranged on the outer walls of the movable clamp 202 and the fixed clamp 201, a side plate 204 is fixedly connected to the side wall of the bottom plate 2, a threaded rod 205 is rotatably connected to the inner wall of the side plate 204, a hand wheel 206 is fixedly connected to the end of the threaded rod 205 away from the movable clamp 202, an end of the threaded rod 205 is rotatably contacted with the outer wall of the movable clamp 202, and a locking mechanism is arranged on the outer wall of the threaded rod 205;

[0023] Furthermore, the locking mechanism includes a limit gear 1 sleeved on the outer side wall of the threaded rod 205, a mounting member 102 is fixedly connected to the front side of the limit gear 1, a locking rod 101 is slidably connected to the inner side wall of the mounting member 102, a tail plate 104 is fixedly connected to the tail of the locking rod 101, a pull ring 105 is provided on the outer side wall of the tail plate 104, connecting plates 103 are fixedly connected to both sides of the tail of the locking rod 101, a tension spring 106 is fixedly connected to the outer side wall of the connecting plate 103, and one end of the tension spring 106 away from the connecting plate 103 is fixedly connected to the outer side wall of the mounting member 102;

[0024] It should be noted that, by setting the retractable dust cover 3, when the movable clamp 202 and the fixed clamp 201 clamp the parts for processing, the cut debris will be blocked by the retractable dust cover 3 and will not adhere to the threaded rod 205, thereby ensuring the use effect of the threaded rod 205. By setting the locking mechanism, the rotation of the threaded rod 205 can be restricted during use, ensuring that the threaded rod 205 will not rotate even if it is subjected to large vibrations, thereby ensuring the fixing effect of the entire flat-nose pliers.

[0025] The working principle of this dust and liquid proof flat nose pliers:

[0026] When in use, the operator can install the base plate 2 on the machine tool. When the part needs to be clamped and processed, the operator can put the part between the movable clamping plate 202 and the fixed clamping plate 201. After placing the part, the operator can pull the locking rod 101 through the pull ring 105 to move the locking rod 101 to the outside of the limit gear 1 and break away from the contact with the limit gear 1. At this time, the operator can rotate the threaded rod 205 through the hand wheel 206. As the threaded rod 205 rotates, the driving screw threaded rod 205 will push the movable clamping plate 202 to move to one side of the fixed clamping plate 201 to clamp the part. When the movable clamp 202 and the fixed clamp 201 have finished fixing the clamped workpiece, the operator can release the pull ring 105. At this time, under the pulling force of the tension spring 106, the locking rod 101 will return to its original position and contact and resist the limit gear 1, ensuring that the threaded rod 205 will not rotate even if it is subjected to a large vibration, thereby ensuring the fixing effect of the entire flat-nose pliers.

[0027] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
