Detailed Description

In order to better understand the purpose, structure and function of the present invention, the following description is made in detail with reference to the accompanying drawings.

As shown in fig. 1-2, a surface grinding machine tool clamp includes a support rod 2 horizontally slidably disposed on a side surface of an electromagnetic platform 1, a top surface of the support rod 2 and a top surface of the electromagnetic platform 1 are located in the same plane, at least two positioning members are disposed on the support rod 2, the support rod 2 is configured to support a portion of a workpiece exceeding the electromagnetic platform 1, and a collecting tank 12 is further disposed under the support rod 2.

When the work piece adds man-hour, the work piece is placed on electromagnetism platform 1, hold the work piece through electromagnetism platform 1, make the grinding machine process the work piece, when the work piece leads to the part too greatly to surpass electromagnetism platform 1 scope, surpass the work piece of electromagnetism platform 1 scope part from the bottom sprag through bracing piece 2, can prevent effectively that the work piece from dropping from electromagnetism platform 1, improve the stability that the work piece was added man-hour simultaneously, and then promote work piece machining precision, the setting element edgewise that sets up on the bracing piece 2 supports and leans on the work piece simultaneously, can prevent that the work piece from taking place horizontal displacement when adding man-hour, further promote the stability that the work piece was added man-hour, and the quantity of setting element can set up a plurality ofly, follow the fixed work piece of equidirectional through a plurality of setting elements, make frock clamp stable and reliable to the support of work piece.

When in actual use, the work piece shape is various, if the mounted position of setting element is fixed unchangeable, can't realize the effective fixed stay to the work piece, consequently the setting element is for being on a parallel with the locating lever 3 that 2 top surfaces of bracing piece set up, the surface parcel of locating lever 3 has the felt layer, make 3 surperficial softnesses of locating lever, prevent that 3 damage workpiece surface of locating lever, threaded mounting hole 5 has been seted up on the bracing piece 2, locating lever 3 passes through bolt and 5 threaded connection of mounting hole, the quantity of mounting hole 5 is at least two, each mounting hole 5 evenly arranges along 2 distribution directions of bracing piece.

The locating lever 3 is fixed with the supporting rod 2 through the bolt, and a plurality of mounting holes 5 are arranged on the supporting rod 2, when the locating lever 3 is connected with different mounting holes 5, the position of the supporting rod 2 can be adjusted, and meanwhile, the locating lever 3 is fixed through the bolt, so that the locating lever 3 can rotate around the bolt, the fine adjustment of the distance between the locating lever 3 and a workpiece is realized, and the locating lever 3 can be effectively abutted to the workpiece.

Locating lever 3 is when fixed through single bolt and bracing piece 2, it is not hard up to connect cloth to take place easily, lead to locating lever 3 to take place to rotate, thereby can't realize effective location, for solving above problem, the top surface of bracing piece 2 covers there is the rubber skid resistant course, the top surface both sides limit downwarping of skid resistant course forms the arc, can make the automatic landing of piece that drops on the skid resistant course through this setting, prevent piece scratch work piece, the skid resistant course can increase the frictional force between bracing piece 2 and the locating lever 3, prevent to take place to skid between locating lever 3 and the bracing piece 2, the while skid resistant course still can alleviate the wearing and tearing between work piece and the bracing piece 2, prevent to take place to skid between the two.

When the position of the supporting rod 2 is fixed, the supporting range is limited, and therefore the electromagnetic platform is not suitable for more workpieces, as shown in fig. 3-4, two through holes are formed in the side surface of the electromagnetic platform 1 adjacent to the supporting rod 2, the axial lead of each through hole is perpendicular to the side surface of the electromagnetic platform 1 adjacent to the supporting rod 2, a sliding rod 4 is connected in each through hole in a sliding manner along the axial direction of the through hole, one end of each sliding rod 4 is fixedly connected with the supporting rod 2, an extending sleeve 7 is coaxially arranged at the end part of each through hole, a connecting hole 9 is vertically formed in each extending sleeve 7, a plurality of positioning holes 8 are vertically formed in each sliding rod 4, each positioning hole 8 is axially arranged along each sliding rod 4, one positioning hole 8 is connected with the connecting hole 9 through a bolt 10, a U-shaped elastic buckle 6 is arranged at the end part of each bolt 10, each extending sleeve 7 is positioned at the inner side of the elastic buckle 6, and the outer peripheral surface of each extending sleeve 7 is abutted to the inner side of the elastic buckle 6, both ends of the elastic buckle 6 protrude inwards to form a limiting part 11.

Slide bar 4 slides along the through hole, can realize the regulation of distance between bracing piece 2 and the electromagnetism platform 1, enlarge the support scope of bracing piece 2, when slide bar 4 adjusts when targetting in place, bolt 10 joint location hole 8 and connecting hole 9, realize the fixed to slide bar 4, prevent that the work piece from adding man-hour, slide bar 4 takes place not hard up, promote the reliability to the work piece support, simultaneously through 6 fixed bolt 10 of elasticity buckle and extension cover 7, prevent that bolt 10 from taking place to drop, and fibre cloth 11 on the elasticity buckle 6 can promote the stability that elasticity buckle 6 and extension cover 7 are connected, and then promote the firmness that bolt 10 pegged graft.
