Detailed Description

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. The present utility model may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the utility model, whereby the utility model is not limited to the specific embodiments disclosed below.

Referring to fig. 1, an whetstone holder comprises a whetstone clamp 1 and a propelling device, wherein a whetstone groove 3 for assembling whetstone is arranged in the whetstone clamp 1, the whetstone is arranged in the whetstone groove 3 in a sliding manner, and the whetstone 3 is propelled to slide by the propelling device and enables a grinding surface of the whetstone to protrude out of the whetstone groove; the propelling device comprises a threaded rod 4 which is connected to the whetstone clamp 1 in a rotating mode and a propelling rod which is arranged on the threaded rod in a sliding mode, the propelling rod comprises a first supporting rod 5 and a second supporting rod 6 which are vertically arranged, the first supporting rod 5 is parallel to the whetstone propelling direction and is in contact with the surface of the whetstone, the second supporting rod 6 is in threaded connection with the threaded rod 4, the threaded rod 4 is rotationally arranged to drive the second supporting rod 6 to slide along the threaded rod 4, the threaded rod 4 is parallel to the whetstone propelling direction, and the second supporting rod 6 is fixedly connected with the first supporting rod 5 and drives the first supporting rod 5 to slide.

Based on the above technical scheme, according to the direction shown in fig. 1, the push rod pushes the whetstone from top to bottom along the direction of the threaded rod, the whetstone is pushed out from the lower surface of the whetstone frame, so that the lower surface of the whetstone protrudes from the whetstone groove, the bearing ring can be superfinished, and the first support rod 5 and the second support rod 6 which are vertically arranged enable the first support rod 5 which is in contact with the whetstone to extend into the whetstone groove 3 to push the whetstone, thereby prolonging the length of the whetstone pushing the whetstone groove.

Further, the threaded rod 4 is pushed to rotate by a hydraulic pushing device, and the pushing rod is restrained by the hydraulic pushing device, so that the pushing rod slides along the threaded rod 4.

Based on the above technical scheme, when using on actual lathe, threaded rod 4 is connected on hydraulic propulsion device, and hydraulic propulsion screw rod is rotatory and can provide the constraint to the propulsion pole, because hydraulic propulsion device is prior art, so hydraulic propulsion device is not drawn.

Further, the bottom of the oilstone fixture 1 extends to one side to form a mounting seat 1.1, and the threaded rod 4 is vertically arranged on the mounting seat and is in rotary connection with the mounting seat 1.1.

Based on the above technical scheme, threaded rod 4 installs on oilstone fixture 1, and the assembly of the oilstone fixture of being convenient for and the position of fixed propelling rod and oilstone.

Further, the second supporting rod 6 and the first supporting rod 5 form an L-shaped structure. The second support rod 6 and the first support rod 5 are integrally arranged, and the second support rod 6 is connected to one end, far away from the oilstone, of the first support rod 5.

Further, the oil stone groove 3 is a hollow groove formed by surrounding four groove walls, and the upper surface and the lower surface of the oil stone groove are opened to form a channel for sliding and pushing the oil stone.

Further, a cushion block 7 is arranged on the surface, in contact with the second supporting rod 6, of the oilstone groove 3, the cushion block 7 is embedded in the side wall of the oilstone groove 3, and a concave cavity 8 matched with the second supporting rod 6 is formed in the cushion block 7. The lower surface of the cavity 8 is lower than the upper surface of the side wall of the oilstone groove.

Based on the above technical scheme, cushion 7 avoids second branch 6 to collide with the whetstone groove, and the lower surface of cavity is less than the upper surface of whetstone groove lateral wall, and when second branch reached whetstone groove upper surface, because the existence of cavity, second branch can continue to push down, avoids whetstone groove lateral wall to hinder second branch to descend, and when whetstone impelled to the bottom, second branch and the lower surface contact of cavity. By arranging the concave cavity, the length of the oil stone pushing oil stone groove is prolonged.

The original oilstone frame structure is adopted to carry out propelling transversely by adopting only one transverse propelling rod, when the propelling device is in contact with the oilstone clamp, the oilstone is 100mm in length and the residual length is 69mm when the propelling is finished, and the use length is 31mm when the propelling device is in contact with the oilstone clamp and takes 100 x 13 x 27 oilstone as an example. The utilization rate of the crude oil stone frame oil stone is as follows: 31%. The original design makes the use ratio of the oilstone lower, generates huge waste, increases superfinishing cost, and therefore needs to be changed.

According to the propelling device of the oilstone frame, the contact point of the propelling device is prolonged, the first supporting rod 5 is prolonged by 18mm, and the concave device is uniquely designed at the contact point of the clamp and the propelling device, so that the contact point continues to extend downwards by 5mm in the radial direction, and the propelling oilstone continues to contact the channel superfinishing. Taking the specification of the oilstone as 100 x 13 x 27 as an example, a newly designed oilstone frame is installed, the oilstone can be continuously used until the length after being unusable is 47mm, and the using length is increased as follows: 22mm, the total use length of the oilstones is: 53mm. The usage rate of the modified oilstone is as follows: 54%. According to actual production needs and measurement after extension, the first support rod 5 is too long to cause instability of the pushing rod, and the first support rod 5 is too short to cause incomplete pushing of the oilstone.
