Description

TECHNICAL FIELD

[0002] In the field of mechanical manufacturing, horizontal machining centers are widely used in the precision machining of box-type, shell-type and large complex workpieces due to their horizontal spindle arrangement, strong worktable carrying capacity and the ability to realize multi-surface and multi-process continuous machining. Deep hole machining, which refers to the machining of holes with a depth-to-diameter ratio greater than 6, plays a key role in high-end manufacturing fields such as energy equipment, aerospace and engineering machinery. The machining quality directly affects the overall performance and reliability of the product.

[0003] However, in the actual machining process of horizontal machining centers, due to the diverse shapes of workpieces to be machined, such as irregularly shaped parts and irregular curved surfaces, the clamping adaptability of traditional tooling is insufficient, which can easily cause the workpiece to shift or shake under the action of cutting force, directly affecting the dimensional accuracy, position accuracy and surface quality of deep holes. In severe cases, it may even cause the workpiece to be scrapped. In addition, a large amount of cutting chips generated during machining, especially fine chips during deep hole machining, can easily scatter and splash, which may not only adhere to the surfaces of key components such as tools and guide rails, causing wear or jamming, but also fall into the machining gap of the workpiece, causing secondary cutting and further affecting the machining quality and equipment service life.

[0036] The working principle of the deep hole machining fixture for a horizontal machining center in this invention is as follows: First, the operator places the workpiece to be machined between two sets of fitting mechanisms. Each fitting mechanism includes a first semicircular plate 21 positioned above a horizontal machining base 201. The first semicircular plate 21 has a first sliding groove 22 on its side that is slidably connected to the horizontal machining base 201. Then, a second semicircular plate 23 is symmetrically slidably connected to the side of the first semicircular plate 21. The second semicircular plate 23 has a second sliding groove 24 on its side that is slidably connected to the first semicircular plate 21. A third semicircular plate 25 is symmetrically slidably connected to the side of the second semicircular plate 23. The third semicircular plate 25 has a third sliding groove 26 on its side that is slidably connected to the second semicircular plate 23. There is a fourth semicircular plate 27, and a fourth sliding groove 28 is opened on the side of the fourth semicircular plate 27, which is slidably connected to the third semicircular plate 25. When the workpiece is placed between the two sets of bonding mechanisms, the motor on the side of the fixed plate 20 is rotated by controlling it. Then the motor drives the first plate side gear 16 to rotate. The second plate side gear 17 is symmetrically meshed on both sides of the first plate side gear 16. The second plate side gear 17 will mesh with the third plate side gear 18 to drive the connecting threaded rod 19 to rotate. This makes the bonding mechanism above the horizontal processing base 201 and the bonding mechanism above the second stabilizing plate 202 move closer to each other, and further makes the workpiece being bonded by multiple sets of fourth semicircular plates 27, so as to adapt to workpieces of different shapes. Figure 1 For example, if the workpiece needs to be moved left or right during the bonding mechanism, the motor on the side of the connecting block 8 is controlled to rotate. The motor passes through the connecting block 8 and drives the second threaded rod 9 to rotate. The rotation of the second threaded rod 9 causes the moving plate 10 to move left or right. When the workpiece needs to be moved longitudinally, the first threaded rod 4 is controlled to rotate. The rotation of the first threaded rod 4 causes the stand 6 to slide above the support rail 5. The stand 6 then drives the mounting plate 7 to move longitudinally, thereby processing the longitudinal part of the workpiece. During the processing, the drilling depth of the deep hole drill rod 15 on the workpiece is adjusted by controlling the meshing of the gear rod 12 and the gear column 13.

[0037] Furthermore, when the deep hole drill rod 15 reaches the workpiece surface, the gear rod 12 will mesh with the electric contact rack 14, so that the electric contact rack 14 just contacts the electric contact sleeve 1401, thereby activating the chip absorption plate 30 to perform chip suction. When the deep hole drill rod 15 performs deep drilling, the electric contact rack 14 continues to penetrate into the electric contact sleeve 1401, and the chip absorption plate 30 continues to perform chip suction. When drilling is completed, the gear rod 12 is controlled to rotate in the opposite direction, so that the electric contact rack 14 slides out of the electric contact sleeve 1401, and the chip absorption plate 30 is in a non-working state.

[0038] While embodiments of the present application have been shown and described, it is to be understood that the embodiments described are merely divergences of the principles and spirit of the present application and that numerous modifications, changes, substitutions, and alterations can be made thereto without departing from the spirit and scope of the present application as defined by the appended claims and their equivalents.
