Description
Technical Field
The utility model relates to a processingequipment of deep hole hydro-cylinder section of thick bamboo spare part specifically is a special jack catch of processing deep hole hydro-cylinder step hole and excircle.
Background
In general processed deep-hole oil cylinder parts, a cylinder barrel is usually a step inner hole (or an excircle), and the inner hole and a spigot are required to be coaxial during processing, such as a common oil cylinder structure shown in fig. 1.
In order to ensure the drawing requirements, the common processing method comprises the following steps: turning an outer circle on a lathe by taking an inner hole as a reference; then, the inner hole and the thread of the big end are turned by taking the turned excircle as a reference, namely, the spigot is turned, so that the requirement on the coaxiality of the inner hole and the spigot is better ensured.
In fact, for the sleeve-inlaid oil cylinder, as shown in fig. 2, after rough machining, a cylinder sleeve (2) of the sleeve-inlaid oil cylinder is welded on a cylinder barrel (1), a spigot portion of the cylinder sleeve (2) is originally larger than an inner hole of the cylinder barrel (1), and in the process of deep hole boring of the inner hole, the spigot portion cannot be bored, so that the requirement of coaxiality between the inner hole and the spigot must be met by finish turning the spigot portion with the bored inner hole as a reference. For the oil cylinder, the length of the spigot is about 120mm generally, the common claw is too short, and the inner hole of the spigot cannot be supported at all, especially for the more common deep-hole oil cylinder with a cladding inner hole recently. As shown in fig. 3, a cladding layer (5) is often arranged on the sealing surface of an inner hole (4) and a spigot (3), the cladding layer (5) is stainless steel or other alloy, the cladding layer (5) is arranged to be in a state similar to a nested cylinder barrel, namely, the inner hole is formed, the spigot part and the inner hole are not formed by one-time boring, and the spigot and the inner hole are not coaxial if the subsequent treatment is not good; to ensure that the bore is coaxial with the spigot, infrared instruments are often used to assist in aligning the bore.
Once the inner hole and the spigot are not coaxial, in order to reduce waste, the spigot part is usually corrected, and threads and a sealing surface are corrected until the threads are not damaged during assembly. However, the influence caused by the operation is obvious, particularly for the cladding oil cylinder, the seam allowance and the inner hole are not coaxial, the cladding layer at the seam allowance part can be deviated to one side when the seam allowance is repaired, the cladding layer at the seam allowance part has uneven thickness, the cladding layer at one side can be completely repaired when the seam allowance is serious, threads present different tooth-shaped depths, the sealing part is in an elliptical state, the stress of the sealing part is uneven, and the cylinder barrel is scrapped.
Disclosure of Invention
The utility model discloses a solve current deep hole hydro-cylinder and add the problem that is difficult for the location man-hour, provide a special jack catch of processing deep hole hydro-cylinder step hole and excircle.
The utility model discloses an adopt following technical scheme to realize: the special jaw for processing the deep hole oil cylinder step inner hole and the excircle comprises three jaw pieces which are uniformly fixed on a lathe chuck, wherein a screw hole is formed in each jaw piece, each jaw piece is fixed in a clamping groove of the lathe chuck by utilizing bolts and nuts, each jaw piece is of a U-shaped cross section, the length of the side edge of one side, close to the lathe chuck, of each jaw piece is greater than that of the side edge of the other side, away from the lathe chuck, the total length L of each jaw piece is greater than that of a spigot of the deep hole oil cylinder to be processed, and the height H.
When the lathe is used, the clamping jaws are arranged on a lathe chuck, after the deep hole oil cylinder hole is bored and formed, the formed inner hole is taken as a reference, the clamping jaws are used for supporting the inner hole to turn an outer circle, and the inner hole and the outer circle are coaxial; because the outer circle is formed by turning the inner hole as a reference, and then the spigot is formed by finish turning by taking the outer circle as a reference, the aim that the spigot and the outer circle are coaxial is achieved; the inner hole is coaxial with the excircle, and the excircle is coaxial with the spigot, so that the spigot is coaxial with the inner hole.
The utility model has the advantages as follows: the deep hole oil cylinder is processed and positioned by utilizing a reasonably designed structure. The utility model has direct double-bracing inner holes, and is convenient to use and clamp; the trouble of aligning the inner hole by using an infrared instrument is saved, the inner hole is aligned by using infrared rays, four-claw clamping is used, and the time is consumed for installation and alignment; the utility model discloses equally be fit for the processing alignment of step excircle, especially when the cylinder liner is thinner, in order to prevent that the cylinder liner from warping, the cylinder liner that can not direct clamping overhang can avoid the weak department of cylinder liner, and the clamping cylinder liner overlaps the position with the hole.

Detailed Description
The special jack catch of processing deep hole hydro-cylinder step hole and excircle, fix three jack catch pieces 6 on lathe chuck 7 including the equipartition, specifically for having seted up the screw on the jack catch piece 6, utilize bolt and nut to fix in lathe chuck 7's draw-in groove 8, jack catch piece 6 is the U-shaped cross-section, wherein be close to lathe chuck 7 one side length and be greater than and keep away from lathe chuck 7 one side, and 6 total length L of jack catch piece are greater than and wait to process deep hole hydro-cylinder tang 3 length, 7 side height H of lathe chuck is greater than tang 3 and hole 4 height are kept away from to jack catch piece 6.
In the specific implementation process, different clamping jaws are designed aiming at different machine tool chucks, so that connecting clamping grooves, hole center distances and the like on the backs of the clamping jaws are matched with the machine tool chucks; the material with reasonable rigidity is selected to ensure the strength and stability of the clamping jaw during use, thereby ensuring the processing precision of workpieces, and the requirements can be met by common steel.
