Description

Magnetic Parallel Cushion Block

Technical Field

[001] The present utility model relates to the machining tooling field, and relates to a magnetic parallel cushion block in particular.

Background Art

[002] In the machining tooling field, flat-nose pliers, commonly used in various machine tools, are used for clamping workpieces, and this facilitates machining of workpieces by cutters. As for clamping of a workpiece, a cushion block is generally provided between a flat-nose plier and the workpiece so as to protect the clamping face of the flat-nose plier and the workpiece.

[003] When existing cushion blocks are provided on the clamping faces of flat nose pliers, most of them are not connected with limiting structural members. Generally, after a cushion block is directly provided between a flat-nose plier and a workpiece, positioning and stable clamping of the cushion block and the workpeice are realized by pre-clamping the workpiece by a flat-nose plier, then adjusting the position of the cushion block, and completely clamping the flat-nose plier at last. Said operation manner is inconvenient, and needs improvement badly.

[004] The inventive object of the present utility model lies in: providing a magnetic parallel cushion block with regard to the problem in the prior art, namely, when existing cushion blocks are provided on the clamping faces of flat-nose pliers, positioning and stable clamping of the cushion block and the workpeice are realized by pre-clamping the workpiece by a flat-nose plier, then adjusting the position of the cushion block, and completely clamping the flat-nose plier at last. Said operation manner is inconvenient, and needs improvement badly.

[005] For realizing the object above, the technical solutions used in the present utility model are as follows:

[006] A magnetic parallel cushion block comprises a cushion block body. The cushion block body comprises a mounting portion comprising a first working face and a second working face which are parallel to each other. The first working face is embedded thereon with at least one magnetic component. The surfaces of all the magnetic components are flush with the first working face or lower than the first working face. The first working face is used for assembly/disassembly on the clamping face of a flat-nose plier by means of the magnetic component, and the second working face is used for fitting a workpiece.

[007] A magnetic parallel cushion block in the present utility model is used. The cushion block body is directly magnetized and fitted on the clamping face of a flat-nose plier by means of the magnetic component, which contributes to convenient connection and arrangement. Also, the magnetic component has limiting and positioning functions. Afterwards, a workpiece can be directly clamped with a flat-nose plier which is provided with the cushion block body.

[014] Further preferably, each of both ends of the mounting portion is connected with the magnetic component.

[015] Preferably, the magnetic components are permanent magnets.

[016] Preferably, the cushion block body further comprises a holding portion, and at least one of both ends of the mounting portion is connected with the holding portion.

[017] During use of such a structure arrangement, the mounting portion is provided on the clamping face of a flat-nose plier, and is used for clamping workpieces. The holding portion is protruding relative to the flat-nose plier, which facilitates an operator's holding and use.

[018] Further preferably, a side face of the holding portion is flush with the second working face.

[019] Further preferably, the holding portion has the same thickness as that of the mounting portion.

[020] Further preferably, the holding portion is a semicircular plate structural member.

[021] Further preferably, the holding portion and the mounting portion are a one piece structural member.

[022] To sum up, due to use of the technical solutions above, the beneficial effects of the present utility model are as follows:

Embodiments

[031] As shown in Figures 1 and 2, a magnetic parallel cushion block in the utility model comprised a cushion block body 1. The cushion block body 1 comprised a mounting portion 11 and a holding portion 12. The mounting portion 11 was a rectangular structural member. The holding portion 12 was provided on one end of the mounting portion 11. As shown in Figure 1, the other end of the mounting portion 11 was a flatheaded structure, facilitating positioning during mounting. The holding portion 12 was a semicircular plate structural member facilitating use and holding thereof, and identification of the direction of the cushion block body 1.

[032] The mounting portion 11 comprised a first working face and a second working face which were parallel to each other. The first working face and the second working face were rectangular. The first working face was embedded thereon with two magnetic components 2. As shown in Figure 2, the surfaces of two of the magnetic components 2 were flush with the first working face. As shown in Figure 1, two of the magnetic components 2 were provided along the long axis of the first working face at interval, and located on both ends of the first working face. The magnetic components 2 were permanent magnets. The first working face was used for assembly/disassembly on the clamping face of a flat-nose plier by means of the magnetic components 2, and the second working face was used for fitting a workpiece.

[033] The holding portion 12 had the same thickness as that of the mounting portion 11. A side face of the holding portion 12 was flush with the second working face. The holding portion 12 and the mounting portion 11 were a one-piece structural member. In use, the mounting portion 11 was provided on the clamping face of a flat-nose plier, and was used for clamping workpieces. The holding portion 12 was protruding relative to the flat-nose plier, which facilitated an operator's holding and use.

[034] The cushion block body 1 was a manganese steel structural member, specifically being 65 Mn. The manganese steel material was made by means of hardening, stress relief and fine grinding, and hardened to HRC55-60 degrees. Using such a structure arrangement prevented the whole cushion block body 1 from being magnetized by a magnetic component 2 such that the whole cushion block body 1 was magnetic. It was difficult to adjust the position of the cushion block body 1 relative to the clamping face of a flat-nose plier, and remove the cushion block body 1 from the clamping face of the flat-nose plier.

[035] The precision of the magnetic parallel cushion block reached: the height of

±0.005mm and width of ±0.01mm.

[036] The magnetic parallel cushion block comprised three groups of different lengths and sizes (the cushion block body 1 had a length of 100mm/125mm/150mm, respectively) for satisfying the requirements for clamping workpieces in different applications. There were two cushion block bodies which were used in pair in each group.

[037] A magnetic parallel cushion block in the present utility model was used. The cushion block body 1 was directly magnetized and fitted on the clamping face of a flat-nose plier by means of the magnetic component 2, which presented convenient connection and arrangement. Also, the magnetic component 2 had limiting and positioning functions. Afterwards, a workpiece could be directly clamped with a flat-nose plier which was provided with the cushion block body 1. It was not necessary to adjust the position of the cushion block body 1. The magnetic parallel cushion block enjoyed a simple structure, convenient use, and good effects.

[038] What were mentioned above were better embodiments in the present utility, but were not used for defining the utility model. Any modifications, equivalent replacements, improvements and so forth within the spirit and principle of the disclosure shall be contained in the scope of protection of the present utility model.
