Abstract
The utility model discloses a static-pressure super-thick guide rail clamping device and belongs to the field of machine tool clamping component devices. An existing floor type borer static-pressure super-thick guide rail clamping device has the defect of being low in clamping force strength. The static-pressure super-thick guide rail clamping device comprises a drive mechanism, a clamping rod and a clamping body. The clamping body comprises a support, two pressing boards and two pressing blocks. A shaft hole is formed in the support, and the clamping rod is arranged in the shaft hole in a penetrating mode. The pressing boards are fixedly arranged at the two ends of the support, and belleville springs are arranged between the pressing boards and the support. The pressing boards are arranged on the clamping rod in a sleeved mode, and the two pressing blocks are fixedly arranged on the two pressing boards respectively. Clamping cavities are formed between the side walls of the two pressing blocks and the bottom face of the support, one end of the clamping rod is fixedly connected with the drive mechanism, the other end of the clamping rod is fixed through a lock nut, and the pressing boards are fixed through lock nuts. According to the static-pressure super-thick guide rail clamping device, through matching of the drive mechanism and the clamping body, clamping force of the clamping device is improved, machining is simple and production cost is low.
Description
Technical field
The utility model belongs to lathe and clamps the part device field, and is especially relevant with a kind of super thick guide rail clamper of static pressure of floor type boring and milling machine.
Background technology
Floor type boring and milling machine is when processing work, and the stability of main spindle box is particularly important, and main spindle box is clamped on the guide rail by clamping device, so whether main spindle box is stably fixed at the key element that has become processing work on the guide rail; Often there is this problem in existing main spindle box clamping device, has caused the precise decreasing of workpiece.
The utility model content
The purpose of this utility model is intended to overcome the not high defective of chucking power intensity that the super thick guide rail clamper of existing floor type boring machine static pressure exists, and the preferably super thick guide rail clamper of static pressure of a kind of chucking power is provided.
For this reason, the utility model is by the following technical solutions: the super thick guide rail clamper of static pressure, it is characterized in that, described clamping device comprises driving mechanism, clamping bar and clamping body, described clamping body comprises bearing, two pressure strips and two briquettings, bearing is provided with axis hole, clamping bar is threaded onto in the axis hole, pressure strip is fixedly installed in the two ends of bearing, between pressure strip and the bearing butterfly spring is set, pressure strip is set on the described clamping bar, two briquettings are fixedly installed in respectively on two pressure strips, and the sidewall of two briquettings and the bottom surface of bearing form the clamping chamber, and an end of clamping bar is fixedly connected with driving mechanism, the other end is fixed by locking nut, and locking nut is fixed pressure strip.Driving mechanism drives bearing, and the moving pressure strip of butterfly spring Zona transformans is done closing motion, has realized the clamping to guide rail, and when needs unclamped guide rail, butterfly spring resiled, and promotes pressure strip and does unlimited motion, has realized unclamping guide rail.
As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature:
Described driving mechanism is hydraulic jack, and cylinder piston rod is fixedly connected with clamping bar.
Use the utility model can reach following beneficial effect: the utility model has improved the chucking power of clamping device by the cooperation of driving mechanism and clamping body, and processing is simple, and production cost is lower.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in detail.
As shown in Figure 1, the utility model comprises driving mechanism 7, clamping bar 4 and clamping body, described clamping body comprises bearing 3, two pressure strips 1 and two briquettings 6, bearing 3 is provided with axis hole, clamping bar 4 is threaded onto in the axis hole, pressure strip 1 is fixedly installed in the two ends of bearing 3, between pressure strip 1 and the bearing 3 butterfly spring 2 is set, pressure strip 1 is set on the described clamping bar 4, two briquettings 6 are fixedly installed in respectively on two pressure strips 1, the sidewall of two briquettings and the bottom surface of bearing form the clamping chamber, one end of clamping bar 4 is fixedly connected with driving mechanism 7, and the other end is fixing by locking nut 5, and driving mechanism 7 drives bearing 3, the moving pressure strip 1 of butterfly spring 2 Zona transformans is done closing motion, realized the clamping to guide rail, when needs unclamped guide rail, butterfly spring 2 resiled, promote pressure strip 1 and do unlimited motion, realized unclamping guide rail.
Preferably, described driving mechanism 7 is hydraulic jack, and cylinder piston rod is fixedly connected with clamping bar 4, and briquetting 6 is preferably alloy material of wearability.
