Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal processing technology, and in particular to an ultra-deep hole segmented processing device. Background Technology
[0002] Ordinary hinges are used for cabinet doors, windows, and other doors. They are made of iron, copper, and stainless steel. A disadvantage of ordinary hinges is that they lack the function of spring hinges; after installation, various door catches must be installed, otherwise the wind will blow the door panel open. Pipe hinges, also called spring hinges, are mainly used for connecting furniture door panels. They generally require a panel thickness of 16-20 mm and are made of galvanized iron or zinc alloy. Spring hinges come with adjusting screws, allowing for vertical and horizontal adjustment of the panel height and thickness.
[0003] Existing drilling equipment exhibits some accuracy deviations when drilling long workpieces, primarily due to vibrations during the drilling process and overly rudimentary positioning devices that fail to provide adequate guidance for machining the shaft hole. Therefore, those skilled in the art have provided a positioning device for machining hinge shaft holes to address the problems mentioned in the background section.
[0004] In the prior art, Chinese Patent Publication No. CN222790698U discloses a positioning device for machining hinge shaft holes, including a positioning assembly. The positioning assembly includes a positioning base, guide holes, guide holes, and positioning elements. Several guide holes are equidistantly arranged above the positioning base, corresponding to the bayonet joint of the hinge workpiece. A guide hole is formed in the center of each guide hole. In use, this invention utilizes the guide holes on the guide holes to guide the drilling equipment for the shaft hole. Continuous guidance by multiple guide holes improves the drilling accuracy of the drilling equipment on the hinge workpiece, reduces drilling offset caused by drilling vibration, and thus reduces the defect rate of the hinge workpiece. It employs a pneumatic clamping structure.
[0005] The existing technical solutions have the following drawbacks: they rely too much on the air source, and there are problems with locking the workpiece when the air source is insufficient. Utility Model Content
[0006] The purpose of this invention is to provide an ultra-deep hole segmented processing device to solve the problems existing in the prior art.
[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0008] A segmented machining device for ultra-deep holes includes a fixed plate. Multiple vertical quick clamps are evenly spaced from left to right on the top front side of the fixed plate. Multiple first positioning components and second positioning components are arranged on the top of the fixed plate. The first positioning components are evenly spaced from left to right, and the second positioning components are also evenly spaced from left to right, with the second positioning components spaced in front of the first positioning components. Each vertical quick clamp consists of a base, a pressure handle, a handle, a latch, and a chuck. The chuck is slidably mounted on the pressure handle via a limiting component, which maintains the perpendicularity of the chuck to the pressure handle.
[0009] By adopting the above technical solution, the vertical quick clamp mechanically fixes the workpiece to the top of the fixed plate, achieving stable clamping of the workpiece, solving the dependence on the air source, and the limiting component maintains the perpendicularity of the clamp and the pressure handle, so that the clamp can stably clamp the workpiece.
[0010] In a further embodiment, the limiting component includes a sleeve, a first limiting piece, and a second limiting piece. The top of the pressure handle is provided with a waist-shaped hole that extends vertically. A first sliding groove is provided on the rear side of the inner side of the waist-shaped hole, and a second sliding groove is provided on the front side of the inner side of the waist-shaped hole. The length direction of both the first and second sliding grooves is left-right. The sleeve is slidably installed inside the waist-shaped hole. The rear side of the sleeve is located in the first sliding groove, and the front side of the sleeve is located in the second sliding groove. The sleeve axis is vertically arranged. The upper and lower surfaces of the first and second sliding grooves are used to mate with the top and bottom surfaces of the sleeve. The inner diameter of the sleeve transitions to the chuck. The top of the chuck passes through the sleeve from bottom to top and extends to the top of the pressure handle.
[0011] By adopting the above technical solution, the transition fit between the sleeve and the chuck allows the sleeve to restrict the top of the chuck. Because the upper and lower end faces of the sleeve are restricted, the sleeve can only slide left and right within the oblong hole, so that the chuck can only move left and right, thus avoiding clockwise and counterclockwise rotation of the chuck.
[0012] In a further embodiment, the sleeve includes an inner ring and an outer ring, with threads provided on the inside of the outer ring and the outside of the inner ring, and the inner ring is screwed onto the inside of the outer ring.
[0013] By adopting the above technical solution, the outer ring is set as a structure of two semi-circular plates spliced together. Both the outer ring and the inner ring are a whole cylinder. During processing, a through shaft hole is first machined on the outer ring, and then a thread is machined. A matching thread is also machined on the outer wall of the inner ring. Then the outer ring is divided into two halves, spliced together and fixed with a clamp. The inner ring is screwed into the inside of the outer ring. Then a shaft hole that transitions with the chuck is machined on the inner ring. During installation, the two semi-circular plates are respectively placed into the waist-shaped hole, spliced together, and screwed into the inner ring, so that the inner ring is completely integrated into one.
[0014] In a further embodiment, the first limiting piece is slidably mounted on the top of the pressure handle, and the second limiting piece is slidably mounted on the bottom of the pressure handle. Both the first and second limiting pieces are provided with vertically penetrating clearance holes, and the clearance holes are collinear with the axis of the sleeve.
[0015] By adopting the above technical solution, since two limiting nuts need to be locked into the pressure head during use to fix it to the pressure handle, in order to avoid the pressure head being deflected after locking the nuts, a first limiting plate and a second limiting plate are used to restrict the contact surface between the nut and the pressure handle. This ensures that the nut only restricts the pressure head to the pressure handle and does not interfere too much with the positioning of the sleeve and the pressure head. Therefore, it is more appropriate to use thin rubber sheets for the first and second limiting plates. The best option is to have a first and second limiting plate with a rubber sheet sandwiched in the middle.
[0016] In a further embodiment, the base is fixedly installed on the top of the fixing plate, the left end of the pressure handle is movably connected to the top left side of the base, the bottom end of the handle is movably connected to the right bottom end of the base, the latch is rotatably installed in the middle section of the handle, and the clamp is movably installed on the pressure handle.
[0017] In a further embodiment, the base is composed of a rear L-shaped plate and a front L-shaped plate.
[0018] By adopting the above technical solution, there is a gap between the rear L-shaped plate and the front L-shaped plate. The bottom ends of the rear L-shaped plate and the front L-shaped plate are both straight edges, and the bottom ends of the rear L-shaped plate and the front L-shaped plate are far apart from each other. The gap between the rear L-shaped plate and the front L-shaped plate is used to allow space for the pressure handle to move.
[0019] In summary, this utility model has the following beneficial effects:
[0020] 1. The workpiece is mechanically fixed to the top of the fixed plate by a vertical quick clamp, which achieves stable clamping of the workpiece, eliminates the dependence on air source, and the limiting component maintains the perpendicularity of the clamp and the pressure handle, so that the clamp can stably clamp the workpiece.
