Abstract
The utility model discloses a boring machine jig for gear holes of a pump body. The jig comprises a fixed plate, two locating rods and a screw rod are fixedly arranged on the fixed plate, the two locating rods penetrate through a back plate and then extend into two locating holes of the pump body for longitudinally locating the pump body, the spatial positions and sizes of the two locating holes are fitted with those of the locating rods; and the screw rod is spirally connected with a propulsion plate, propulsion rods are also arranged on the propulsion plate, the propulsion rods are fitted with two obliquely arranged mounting holes of the pump body in the spatial positions and sizes, a tool withdrawal groove is arranged in the front end of each propulsion rod, the screw rod is rotated to drive the propulsion plate and the propulsion rods on the propulsion plate to move forward, the propulsion rods extend out from the mounting holes of the pump body, and limiters are clamped and fixedly arranged at the tool withdrawal grooves for horizontally locating the pump body and limiting the horizontal movement of the pump body. Through leveling of the back plate, the rotation of the screw rod and the limiting of the limiters, the boring machine jig can effectively clamp and locate a workpiece, and is short in working time and high in working efficiency, as well as easy to clamp and convenient to operate.
Description
Technical field
The utility model relates to a kind of fixture for boring machine, is specifically related to a kind of fixture for boring machine of pump housing gear hole.
Background technology
The pump housing is a kind of common hydraulic part, when its gear hole of processing, usually workpiece is lain against boring table, selects vertical boring mill to process.Because pump housing gear hole size is larger, select the vertical boring mill processing mode, workpiece is longer process time, therefore, selects under normal circumstances horizontal boring machine processing relatively good.Because boring machine form, tool feeding mode difference, original vertical boring mill anchor clamps can not be applicable to horizontal boring machine processing.
Summary of the invention
The technical problems to be solved in the utility model is to change existing pump housing gear hole processing mode, provide a kind of simple to operate, crudy is guaranteed, man-hour is short, high efficiency and be applicable to the fixture for boring machine of a kind of pump housing gear hole of horizontal boring machine processing.
The utility model is achieved through the following technical solutions:
A kind of fixture for boring machine of pump housing gear hole, these anchor clamps comprise fixed head, are fixed with backstay and screw rod on it, and described backstay is two, stretch in two locating holes of the pump housing that matches with its locus, size after wearing backboard, the pump housing is carried out longitudinal register; Described screw rod is connected with the pushing plate spiral, be fixedly connected with and the installing hole locus of two oblique settings of the pump housing, the pushing ram that size matches at pushing plate, front end at pushing ram is provided with escape, rotating screw bolt, the pushing ram that drives on pushing plate, the pushing plate travels forward, and pushing ram stretches out from the installing hole of the pump housing, and stop is fastened on the escape place, the pump housing is carried out located lateral, restriction pump housing transverse shifting.
The further improvement project of the utility model is, described stop comprises a collar and two coupled ring heads, and described ring head is the cylinder that a side milling has flat groove, and the escape place diameter of the groove width of flat groove and pushing ram matches.
The utility model compared with prior art, have following obvious advantage: the utility model by backboard to workpiece by flat, the pushing ram that drives on pushing plate, the pushing plate by rotating screw bolt seesaws, by stop the pump housing is carried out located lateral again, restriction pump housing transverse shifting is effectively implemented clamping and location to workpiece, and process time is short, high efficiency, the workpiece crudy is stable.Simultaneously, the utility model clamping is light, and is easy to operate.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the P of Fig. 1 is to structural representation.
Fig. 3 is that the F of Fig. 2 is to structural representation.
The specific embodiment
Processing unit (plant) is milled on a kind of pump housing surface, and with reference to Fig. 1,2,3, this device comprises fixed head 1, is fixed with backstay 2 and screw rod 3 on it:
Described backstay 2 is two, stretches in two locating holes 41 of the pump housing 4 that matches with its locus, size after wearing backboard 5, and the pump housing 4 is carried out longitudinal register;
Described screw rod 3 is connected with pushing plate 6 spirals, also is provided with on pushing plate 6 and installing hole 42 locus of two oblique settings of the pump housing 4, the pushing ram 7 that size matches, and is provided with escape at the front end of pushing ram 7;
Stop 8 comprises a collar 81 and coupled two rings 82, and described ring 82 is the cylinder that a side milling has flat groove, and the escape place diameter of the groove width of flat groove and pushing ram 7 matches, and the ring of stop 8 82 is fastened on the escape place;
By rotating screw bolt 3, the pushing ram 7 that drives on pushing plate 6, the pushing plate 6 travels forward, and pushing ram 7 stretches out from installing hole 42, carries out located lateral by 8 pairs of pump housings of stop 4 again, the restriction pump housing 4 transverse shiftings.Screw rod 3 rod ends are connected with rocking bar 9, and the rotation of screw rod 3 realizes by shaking rocking bar 9.
