Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The first embodiment is as follows:

a machining device of a spindle box is shown in attached figures 1 and 2 and comprises a tool body 1 which is a rectangular upright column-shaped frame. The front surface and the back surface of the tool body 1 are communicated, and the back surface of the tool body 1 is provided with a placing inlet 15 for placing a spindle box. And four supporting blocks 14 are arranged on the inner bottom surface of the tool body 1 and are distributed in a rectangular shape. Thereby, can be used for the four apex angles of butt headstock bottom.

In addition, the edge of one side of the front surface of the tool body 1 is provided with a butting piece 2, and the butting piece 2 is slightly higher than the upper surface of the supporting block 14. In this way, the contact piece 2 and one of the support blocks 14 just form a positioning angle, thereby facilitating the initial placement of the spindle box.

Moreover, the end part of the abutting sheet 2 facing the spindle box is provided with a circular rubber block 21, which can play a role of buffering when the spindle box is put into the tool body 1, and the collision between the spindle box and the abutting sheet 2 is reduced, so that the damage is reduced. In addition, because the temperature of the processing environment is often high, and the traditional rubber block 21 is not high-temperature resistant, the rubber block is often melted and stuck on the spindle box.

For this purpose, the rubber block 21 is mainly formed by melting and mixing 50 parts by mass of silicone rubber, 0.4 part by mass of potassium iodide, 4 parts by mass of shell powder, 0.1 part by mass of benzoyl peroxide and 2 parts by mass of zinc oxide, and then transferring the mixture to a screw extruder for extrusion cutting. Furthermore, here the method for preparing shell powder: firstly, preparing a sodium sulfite buffer solution with the pH of 8.0, using a small amount of triton as a surfactant, respectively using combined enzymes of alkaline protease, papain, trypsin and other enzymes as catalysts, soaking shells in the sodium sulfite buffer solution, and hydrolyzing for 2 hours under the conditions that the temperature of a constant temperature shaking table is controlled to be 50 ℃ and the rotating speed is 300 r/min. Thereafter, the shell was ground to a shell powder having an average particle size of 10 μm.

Since the shell powder contains calcium carbonate as a main component, the shell powder can effectively enhance the molding effect of the rubber block 21 as a filler. Secondly, the shell powder can secrete chitin under the enzymolysis, and the chitin not only has good antibacterial effect, but also can enhance the bonding effect of each molecule in the rubber block 21, so that when the rubber block 21 is heated, the intermolecular effect can be stronger, and the probability that the rubber block is adhered to a spindle box is reduced. In addition, lithium iodide not only improves the stability of the rubber block 21 due to its own physical properties, compared to other iodide salts. Meanwhile, lithium ions in the lithium iodide can also have a coordination effect with carbonyl in the rubber block 21, a network-like structure is generated, and the movement of a rubber molecular chain and corresponding free radicals is hindered, so that a larger energy barrier needs to be overcome than that of a completely free molecular chain when a polymer molecular chain is decomposed by heat, and the rubber block 21 has a higher thermal decomposition temperature.

Here, the present application also performs high temperature resistance detection on the rubber block 21, that is, the deformation of the rubber block is observed as the temperature rises, and the following table is obtained:

temperature/. degree.C	100	120	130	150	180	200	220	240	260
										Whether or not to deform	Whether or not	Whether or not	Whether or not	Whether or not	Whether or not	Whether or not	Whether or not	Whether or not	Whether or not
Temperature/. degree.C	270	280	290	300	310	320	330	340	350
										Whether or not to deform	Whether or not	Whether or not	Whether or not	Whether or not	Whether or not	Whether or not	Whether or not	Slightly deformed	Apparent deformation

As is apparent from the above table, the high temperature resistance of the rubber block 21 is higher than that of the general silicone rubber at 300 ℃, and even can reach over 330 ℃, so that the rubber block is prevented from being adhered to the spindle box due to melting caused by over-high temperature in the machining process of the spindle box.

Secondly, two surfaces of the tool body 1 are respectively provided with a processing hole I11 and two symmetrical arc openings 13, wherein the processing hole I is corresponding to a secondary hole I8 c, a secondary hole II 8d and a secondary hole III 8e of the spindle box, and a boring cutter for processing can penetrate through the processing hole I and the two symmetrical arc openings. The two arc openings 13 are located on both sides of the opening 15. Therefore, not only can space be provided for the second auxiliary hole 8d and the third auxiliary hole 8e, but also the operation of workers is facilitated. And, the top of frock body 1 has cylinder 3, and the piston rod of cylinder 3 can carry out the up-and-down concertina movement. The end of the piston rod of the cylinder I3 is provided with a rectangular pressure plate 31. An elastic pressing block 32 is respectively arranged near four vertex angles of one surface of the pressing plate 31 facing the top of the spindle box. Each elastic pressing block 32 corresponds to four vertex angles at the top of the main shaft box respectively, and the elastic pressing block 32 is a rectangular block with a telescopic spring, wherein one end of the telescopic spring, which is far away from the rectangular block, is fixed with the pressing plate 31. The design can be designed according to actual conditions. Like this when clamp plate 31 pushes down, elastic pressing block 32 also can play the cushioning effect to when guaranteeing to carry out the stability to the headstock, also can reduce the damage that causes the headstock.

Furthermore, the front of the tool body 1 is provided with a limiting plate 4 capable of sliding up and down, and the upper edge of the limiting plate 4 can be abutted to the lower surface of the spindle tube hole 8 a. And the upper surface of the limit plate 4 is also provided with a U-shaped gap which is matched with the main shaft pipe hole 8 a. The probability of shaking of the spindle tube hole 8a in the machining process is reduced, and the machining accuracy of the spindle tube hole 8a is improved. Moreover, the front surface of the tool body 1 is provided with a vertical cylinder four 41 on each of two sides of the limiting plate 4, and piston rods of the two cylinders four 41 are fixed with two sides of the limiting plate 4 respectively, so that the limiting plate 4 can be driven to slide up and down.

Here, after the spindle box is placed into the tool body 1 and is initially positioned and placed, the first cylinder 3 pushes the pressing plate 31 to press the top of the spindle box, and the fourth cylinder 41 can drive the limiting plate 4 to ascend to abut against the spindle pipe hole 8 a. Thereby guaranteed the stability of headstock, staff just also can carry out accurate bore hole processing to the headstock this moment.

And the outside of the other side of the tool body 1 is provided with a second air cylinder 5b, and a piston rod of the second air cylinder 5b penetrates through the side where the second air cylinder is located and corresponds to the abutting block 5 a. And the end of the piston rod of the cylinder II 5b is provided with a horizontally arranged abutting plate 5b1, and the center of the abutting plate 5b1 is as high as the abutting block 5 a. While the lower edge of the abutment plate 5b1 is flush with the upper surface of the support block 14. Like this when the headstock is put into in the frock body 1 after, cylinder two 5b will drive butt plate 5b1 for the headstock can be held under the effect of butt plate 5b1 and butt piece 5a, thereby has further improved the stability of headstock.

Moreover, in order to make the tool body 1 be suitable for processing more headstocks of different sizes, the supporting block 14 and the abutting block 5a are connected with the tool body 1 through the screw rod, so that the telescopic distance of the supporting block 14 and the abutting block 5a can be adjusted, and the machined headstocks can be drilled at specified positions.
