Description
Technical Field
The utility model relates to a hydraulic pump, concretely relates to compression structure of cross head baffle on hydraulic pump.
Background
In a common hydraulic pump, a power end (such as a motor) drives a crankshaft to rotate, a large end of a connecting rod is connected with the crankshaft, a small end 4 of the connecting rod is connected with one end of a crosshead 3 through a crosshead pin 5, and the other end of the crosshead 3 is connected with a piston, so that the piston is driven to reciprocate, and pumping of a medium is realized. In order to better guide the crosshead 3 and facilitate quick and low-cost repair of the worn base 1, a crosshead guide plate 2 is arranged on a base channel for running the crosshead at present, the guide plate 2 corresponding to each crosshead is divided into an upper guide plate and a lower guide plate, and each guide plate is arc-shaped and is arranged on the base 1. The crosshead is driven by the connecting rod to reciprocate along the inner arc surface of the guide plate. Meanwhile, in order to improve the pumping capacity, a plurality of sets of the connecting rod, the crosshead and the piston mechanism are horizontally arranged side by side, and three sets are shown in figure 1.
The conventional guide plate compression structure is shown in figure 1, wherein bolt through holes and counter bores are processed on a guide plate 2, threaded holes are processed on a machine base 1, and then the guide plate compression structure is connected to the machine base 1 through hexagon socket head cap screws 10. In order to ensure that the guide plate 2 is better attached to the base 1, a plurality of socket head cap screws 10 are arranged on the circumference, namely, part of the socket head cap screws are distributed at an included angle alpha with the vertical direction. The compact structure has the following defects: 1. the machine seat threaded hole has large processing difficulty: because the threaded holes are machined in the inner hole wall, and the included angles alpha are formed between partial threaded holes and the vertical direction, the machining is difficult. 2. The assembly is difficult: during assembly, the through holes in the guide plate and the threaded holes in the base are aligned to be installed, and assembly difficulty is increased. 3. The slide surface 9 of the guide plate is incomplete: as the guide plate 2 needs to be processed with counter bores, the slide way surface 9 is damaged, and the direct effect is to increase the specific pressure of the crosshead. Such as the un-rounding of the sharp corners of the counterbore, may also result in scratching of the babbitt metal layer of the crosshead surface. 4. Partial screw loosening or breakage can scratch the crosshead: the screws can break if they loosen during operation, and the broken screws can severely scratch the babbitt metal layer on the surface of the crosshead.
SUMMERY OF THE UTILITY MODEL
The aforesaid that exists to prior art is not enough, the utility model aims at providing a compression structure of cross head baffle, and this structure has not only solved the problem that compresses tightly of baffle, can ensure the integrality of the slideway face of baffle again, and processing is simple, simple to operate's advantage in addition simultaneously.
In order to solve the technical problem, the utility model discloses a following technical scheme:
the utility model provides a compression structure of cross head baffle, includes the frame, is equipped with the cross head passageway on the frame, installs two about the curved baffle of dead right in the cross head passageway, its characterized in that: the left side and the right side of each guide plate are provided with a plurality of pressing blocks, each pressing block is provided with an inclined plane corresponding to the side face of the guide plate, each pressing block is fixedly installed on the base through a bolt, the side face of each guide plate is tightly pressed through the inclined plane, so that the outer arc face of each guide plate is tightly attached to the wall face of the crosshead channel, and the bolts are vertically arranged.
The crosshead channels are arranged in parallel and are sequentially communicated, and an upper guide plate and a lower guide plate are arranged in each crosshead channel; the pressing blocks between two parallel guide plates in two adjacent crosshead channels are shared mutually, both sides of the shared pressing blocks are provided with inclined planes, and the inclined planes correspond to the side faces of the corresponding sides of the guide plates on both sides so as to simultaneously press the two guide plates.
And the bolt is provided with a locking nut and a locking washer.
The utility model discloses with the baffle compress tightly the position adjustment to the edge about the baffle, increase the toper briquetting simultaneously and ensure that baffle and frame laminating are inseparable. Compared with the prior art, the utility model discloses following beneficial effect has:
1. the processing is convenient. The guide plate is not required to be provided with any through hole, and the screw holes on the base are distributed in the vertical direction without an included angle alpha, so that the processing amount is less and more convenient.
2. The assembly is convenient. The conical pressing block has a self-guiding function, and the guide plate can be tightly attached to the machine base only by ensuring that the moment of each pressing bolt is the same during installation.
3. Integrity of the slide face of the guide plate. The guide plate is not provided with any through hole, so that the integrity of the slide way surface is ensured, and the specific pressure of the crosshead is reduced.
4. The surface of the crosshead cannot be scratched after part of the bolts are loosened or broken.
5. The automatic locking effect of housing bolt. When the conical pressing block is used for pressing the guide plate, the guide plate arc structure enables the conical pressing block to have certain elasticity, the conical pressing block can give a rebound force to the conical pressing block, and the rebound force finally acts on the bolt, so that the bolt has a good automatic anti-loosening function.
