Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, specifically relating to a machine tool hard rail insert with a shovel fixture. Background Technology

[0002] Scraping is the process of manually scraping the surface of a metal workpiece using a special scraper (also known as a scraper) with a sharp blade and specific techniques (pushing, pressing, and picking).

[0003] Improving contact precision: This is the primary objective. By scraping, two sliding surfaces requiring precise fit (such as the hardened rail surface and the insert contact surface mentioned in the document) can be scraped to achieve a very high contact rate. Ideally, there should be a sufficient number of evenly distributed contact points per unit area. Forming oil reservoirs: Scraping leaves tiny pits on the surface. These pits can store lubricating oil, forming an oil film during the movement of sliding parts, reducing friction and wear, and improving the guide rail's precision retention and lifespan. Correcting errors: It can correct residual shape errors (such as flatness, straightness) and positional errors after machining (such as milling and grinding).

[0004] When fitting a shovel, the insert and the contact surface need to move relative to each other. A common method on the market is to install a lead screw nut, lock a rotating handle on the lead screw, and rotate the handle to cause relative displacement between the insert and the hardened guide surface of the spindle box (e.g., ...). Figure 1 The spindle box is manually pushed to move on the saddle.

[0005] However, existing scraping devices rely on rotating a handle to drive a lead screw, causing the spindle box to translate. This translational stroke is limited and prone to interference with the handle, affecting scraping efficiency. Manual pushing is labor-intensive, and the required force increases with the Z-axis stroke, making it difficult for a single adult to meet the demands. Furthermore, scraping is not a single push but requires repeated pushing, further impacting efficiency.

[0006] This utility model addresses the above-mentioned problems by providing a machine tool hardened rail insert with a shovel fixture. Utility Model Content

[0007] The purpose of this invention is to provide a machine tool hardened guide rail insert with a scraper fixture, to solve the problems mentioned in the background art regarding existing scraping devices that rely on a rotating handle to drive a lead screw, causing the spindle box to translate. However, the translational stroke is limited, easily interfering with the rotating handle and affecting scraping efficiency. Manual pushing is labor-intensive, and the required pushing force increases with the Z-axis stroke, making it difficult for a single adult to meet the requirements. Furthermore, scraping is not a single push but requires repeated pushing, further impacting scraping efficiency.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a machine tool hard rail insert with shovel fixture, including a saddle cylinder connecting frame and a spindle box piston rod connecting frame provided on the left side of the saddle cylinder connecting frame;

[0009] A muffler is located at the front of the saddle cylinder connecting frame. A direct air pipe connector is located on the right side of the muffler. A manual control valve is located at the lower front of the muffler. A speed control valve is located at the front of the manual control valve. A cylinder mounting plate is located on the upper side of the saddle cylinder connecting frame. A connecting drive cylinder is located on the side of the cylinder mounting plate. An air pipe elbow is located on the upper side of the connecting drive cylinder near both ends.

[0010] Preferably, a cylinder connecting lifting shaft is provided at the middle position of the side of the connecting drive cylinder, and the cylinder connecting lifting shaft is telescopically connected to the connecting drive cylinder.

[0017] Compared with the prior art, this utility model provides a machine tool hardened rail insert with a spade fixture, which has the following beneficial effects:

[0018] 1. In the machine tool hardened rail insert jig fixture, a silencer is located at the front of the saddle cylinder connecting frame. A direct air pipe connector is located on the right side of the silencer. A manual control valve is located at the lower front of the silencer, and a speed regulating valve is located at the front of the manual control valve. A cylinder mounting plate is located on the upper side of the saddle cylinder connecting frame, and a connecting drive cylinder is located on the side of the cylinder mounting plate.

The operator can achieve three-dimensional fine-tuning through the manual control valve, which can now be completed independently by a single person. The speed regulating valve can dynamically adjust the air pressure and flow rate according to different guide rail weights, achieving speed variation within a certain range. Scraping requires repeated verification of the contact point distribution, and traditional manual pushing and pulling is time-consuming. This system, through a pneumatic locking-release mechanism, reduces the single displacement operation time from three to five minutes to within ten seconds, improving overall efficiency by four to six times. To address the displacement requirements of the Z-axis spindle box of a gantry milling machine, the pneumatic system can output stable thrust, completely replacing manual pushing and pulling.

A bottom limiting moving groove is provided at the outer position of the bottom limiting moving block and inside the mounting side connection frame. When installing the shaft connection mounting plate and the spindle box piston rod connection frame, the installation can be completed by simply plugging in the slope connection telescopic snap-fit ​​block. When disassembly is required, simply press the telescopic connection button to allow the gas inside the telescopic connection body to enter the venting connection pipe. The increased air pressure in the venting connection pipe will drive the piston connection moving column to move the slope connection telescopic snap-fit ​​block. The movement of the slope connection telescopic snap-fit ​​block will retract it and remove the snap-fit, thus achieving disassembly. Its installation and disassembly method is simple and quick, which can effectively improve the installation and disassembly efficiency of workers and the practicality of machine tool hard rail inserts with shovel fixtures.
