Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically to a fixture suitable for processing the positive blowing arm in a bottle making machine. Background Technology

[0002] Bottle-making machines (such as row-type bottle-making machines) are the most common glass bottle production equipment in existing technology. Glass droplets undergo multiple processing steps within the bottle-making machine to ultimately become finished glass bottles. Positive air blowing is a crucial step in the glass bottle manufacturing process, forming the bottle within the molding die. The glass droplet undergoes reverse air blowing in the initial mold to form a preliminary preform. This preform is then transferred by a flipping mechanism to the molding die where positive air blowing is performed, ultimately forming the finished preform.

[0003] In existing bottle-making machines, positive blowing is achieved by a positive blowing arm, which is typically machined on a horizontal machining center. The preform of the positive blowing arm is fixed within the machining center and then machined through steps such as milling and planing. In existing technology, the positive blowing arm needs to be positioned before machining in the horizontal machining center. The positioning device is generally a fixture composed of a hydraulic cylinder and a pressure plate. Refer to the technical solutions described in patent applications 202322346295.5, 202610016756.8, and 202511437258.2.

[0004] However, due to the different structures of various products, the fixture solutions mentioned above are not interchangeable. Furthermore, because the positive blowing arm involves lifting, swinging, and other movements during operation, and also needs to deliver air, its complex structure requires machining at numerous locations. Traditionally, when using fixtures to hold and position the workpiece before machining, the workpiece's machining location is easily obscured by pressure plates and other components. Therefore, multiple disassemblies and reassemblies of the workpiece are required using different positioning devices to expose different machining locations before completion. This process is not only cumbersome but also inefficient. Therefore, designing a fixture specifically for machining positive blowing arms that also improves machining efficiency has become a pressing issue in this field. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a fixture for the processing of the air blowing arm in a bottle making machine, which is provided with a horizontal clamping component and a vertical clamping component along the fixing direction of the air blowing arm, especially suitable for clamping and fixing the air blowing arm so as to further process it through a horizontal machining center.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: the fixture applicable to the processing of the positive blowing arm in a bottle making machine includes a fixed frame, a clamping station for fixing the workpiece is provided on the fixed frame, and a clamping component for clamping and fixing the workpiece is provided in the clamping station. The workpiece is a positive blowing arm, and the clamping component includes a horizontal clamping assembly for clamping and fixing the positive blowing arm in the horizontal direction, and a vertical clamping assembly for clamping and fixing the positive blowing arm in the vertical direction. The horizontal clamping assembly and the vertical clamping assembly are arranged along the fixing direction of the positive blowing arm.

[0007] Preferably, the fixing frame includes a base and an upright plate, the upright plate is vertically fixed to the surface of the base, and the clamping station is set on the surface of the upright plate.

[0008] Preferably, multiple clamping stations are provided on the surface of the vertical plate.

[0009] Preferably, the surface of the upright plate is provided with a perforated hole for displaying the machining position on the back side of the air blowing arm, and multiple perforated holes are provided along the fixing direction of the air blowing arm.

[0010] Preferably, the clamping component is a hydraulic device, and hydraulic channels for supplying driving fluid to the clamping component are provided in the base and the upright plate.

[0011] Preferably, an upright plate oil passage is provided in the upright plate and a base oil passage is provided in the base. The upright plate oil passage and the base oil passage are connected at the mating surface of the upright plate and the base to form a hydraulic channel. The upright plate oil passage extends to each hydraulic component.

[0012] Preferably, the vertical clamping components are arranged vertically on the side of each cutout hole, with their moving ends facing the cutout holes, and the horizontal clamping components are arranged between adjacent cutout holes.

[0013] Preferably, the vertical clamping assembly includes a lower clamping cylinder and an upper clamping cylinder located at one end of the positive air blowing arm, a second shaft hole positioning cylinder located at the other end of the positive air blowing arm, and a first shaft hole positioning cylinder located in the middle of the positive air blowing arm; wherein the lower clamping cylinder and the upper clamping cylinder are arranged vertically opposite each other.

[0014] Preferably, the horizontal clamping assembly includes multiple sets of lever cylinders disposed between two adjacent hollow holes, each set of lever cylinders including multiple cylinders disposed opposite to each other.

[0015] Preferably, multiple positioning posts are provided on the side of the clamping station.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In the fixture for machining the blow-up arm in a bottle-making machine according to this application, a horizontal clamping component and a vertical clamping component are provided along the fixing direction of the blow-up arm, which is particularly suitable for clamping and fixing the blow-up arm so that it can be further processed by a horizontal machining center.

[0018] Multiple perforations are also provided on the surface of the vertical plate. By setting the perforations, the part to be processed on the back side of the front air blowing arm can be exposed so that it can be processed by the horizontal machining center. This effectively avoids the drawback of having to disassemble and assemble the front air blowing arm of the workpiece when processing the front and back sides separately, and improves the processing efficiency.

[0019] By setting two clamping stations on the vertical plate surface, the horizontal machining center can process two workpieces sequentially, thus improving processing efficiency.

[0020] The horizontal clamping assembly is achieved through a lever cylinder. Taking advantage of the small space occupied by the lever itself in the lever cylinder, it is more effective in avoiding the position to be processed on the surface of the positive blowing arm.

[0021] Lifting rings are provided at the four corners of the base and along the upper edge of the uprights to facilitate hoisting. Attached Figure Description

[0028] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5 The present invention will be further described below.

[0029] like Figures 1-2 As shown, a fixture (hereinafter referred to as the fixture) suitable for machining the blow arm in a bottle-making machine includes a base 2, a vertical plate 3 vertically arranged on the surface of the base 2, and lifting rings 1 arranged at the four corners of the base 2 and the upper edge of the vertical plate 3 for lifting the fixture. The base 2 is fixed to the rotary table (i.e., cradle table) in the horizontal machining center so as to further realize the displacement of the fixture in various directions during subsequent machining processes.

[0030] The surface of the vertical plate 3 is the clamping surface of the workpiece 18 to be processed, see... Figure 5 Two clamping stations are vertically arranged on the surface of the vertical plate 3, each capable of clamping and fixing one workpiece 18. By setting two clamping stations on the surface of the vertical plate 3, the horizontal machining center can process two workpieces 18 sequentially, improving processing efficiency. Each clamping station is equipped with several hydraulic devices for clamping and fixing the workpiece 18.

[0031] A one-way valve 14 is fixed to the side of the surface of the base 2. Together with the base 2 and the upright plate 3, they form the hydraulic pipeline for each hydraulic device in each clamping station. External hydraulic oil is connected to the inlet of the one-way valve 14 through a pipeline (not shown in the figure). The outlet of the one-way valve 14 is connected to the hydraulic pipeline formed by the base 2 and the upright plate 3, further delivering the hydraulic oil to each hydraulic device to drive the hydraulic device.

[0032] Combination Figure 3 Several base oil passages 17 are provided inside the base 2, and several vertical plate oil passages 16 are provided inside the vertical plate 3. It should be noted that because there are a large number of vertical plate oil passages 16 in the vertical plate 3, therefore... Figure 3 Only one of the vertical plate oil passages 16 is marked. After the one-way valve 14 is fixed to the side of the base 2, the inlet of the base oil passage 17 is connected to the outlet of the one-way valve 14; the outlet of the vertical plate oil passage 16 extends to each hydraulic device in each clamping station. After the hydraulic device is fixed to the surface of the vertical plate 3, the hydraulic inlet of the hydraulic device is connected to the outlet of the vertical plate oil passage 16 at the corresponding position; at the same time, after the vertical plate 3 is fixed to the base 2, at the joint surface of the vertical plate 3 and the base 2, the inlet of the vertical plate oil passage 16 is connected to the outlet of the base oil passage 17 to form a hydraulic pipeline, thereby realizing the connection between the external hydraulic oil and each hydraulic device.

[0033] Several base plugs 4 are provided on the side of the base 2 to seal the ports of the base oil circuit 17. Similarly, several vertical plate plugs 5 are provided on the side of the vertical plate 3 to seal the ports of the vertical plate oil circuit 16, preventing hydraulic oil leakage during subsequent operation. A pressure gauge 11 is also provided on the surface of the vertical plate 3, connected to the hydraulic pipeline for monitoring the hydraulic oil pressure.

[0034] Within each clamping station, according to the structure of the workpiece 18 (i.e., the blank of the positive blowing arm), multiple positioning posts 15 are vertically arranged on the surface of the vertical plate 3. The positioning posts 15 serve the following functions: to pre-position the workpiece 18 and pre-fix the workpiece 18 within the corresponding clamping station. Combined with... Figure 4 In each clamping station, along the contour of the workpiece 18, multiple hollow holes 7 are also provided on the surface of the vertical plate 3. By setting the hollow holes 7, the back side of the workpiece 18 to be processed is exposed so that the horizontal machining center can process it. This effectively avoids the disadvantage of needing to disassemble and assemble the workpiece 18 when processing the front and back sides separately, and improves the processing efficiency.

[0035] Within each clamping station, the hydraulic components include a vertical clamping assembly for vertically positioning the workpiece 18, and a horizontal clamping assembly for horizontally positioning the workpiece 18. The vertical clamping assembly includes a second shaft hole positioning cylinder 12 located on one side of the vertical plate 3, a lower clamping cylinder 6 and an upper clamping cylinder 8 located on the other side of the vertical plate 3, and a first shaft hole positioning cylinder 10 located in the middle of the clamping station. The first shaft hole positioning cylinder 10, the second shaft hole positioning cylinder 12, the lower clamping cylinder 6, and the upper clamping cylinder 8 are all implemented using commercially available cylinders.

[0036] The piston rods of the first shaft hole positioning cylinder 10 and the second shaft hole positioning cylinder 12 point downwards, and each piston rod faces a hollow hole 7. A shaft hole positioning seat 13 is also provided below the second shaft hole positioning cylinder 12. The second shaft hole positioning cylinder 12 and the shaft hole positioning seat 13 are spaced apart from their corresponding hollow holes 7. The lower clamping positioning cylinder 6 and the upper clamping positioning cylinder 8 are arranged vertically opposite each other, and are respectively positioned on the upper and lower sides of the corresponding hollow holes 7.

[0037] As can be seen from the above, all the hydraulic cylinders that make up the vertical clamping assembly together achieve the clamping of the workpiece 18 in the vertical direction.

[0038] The horizontal clamping assembly includes two sets of lever cylinders 9 arranged side by side. Each set of lever cylinders 9 is positioned between any two hollow holes 7: one set of lever cylinders 9 is positioned between the two hollow holes 7 corresponding to the first shaft hole positioning cylinder 10 and the second shaft hole positioning cylinder 12; the other set of lever cylinders 9 is positioned between the two hollow holes 7 corresponding to the first shaft hole positioning cylinder 10 and the lower clamping cylinder 6 (upper clamping cylinder 8). Each set of lever cylinders 9 has two cylinders arranged vertically opposite each other.

[0039] The purpose of using a lever cylinder 9 instead of a conventional cylinder to fix the workpiece 18 to the surface of the vertical plate 3 between two adjacent hollow holes 7 is to fix the workpiece 18 to the surface of the vertical plate 3, that is, to fix it in the horizontal direction. Taking advantage of the small space occupied by the lever in the lever cylinder 9, it is more conducive to avoiding the position to be processed on the surface of the workpiece 18.

[0040] The specific operating method and process are as follows:

[0041] like Figure 5 As shown, the workpiece 18 to be processed is placed on the surface of the vertical plate 3. During the placement process, the workpiece 18 is pre-fixed by the positioning post 15, and the fixing hole at the bottom of the shaft hole at the end of the workpiece 18 is clamped and fixed by the shaft hole positioning seat 13.

[0042] Then, the external oil circuit sends hydraulic oil in. The hydraulic oil enters through the one-way valve 14, and then passes through the hydraulic oil circuit consisting of the base oil circuit 17 and the vertical plate oil circuit 16 to the hydraulic components in each clamping station. Then, the piston rods of the lower clamping positioning cylinder 6 and the upper clamping positioning cylinder 8 output to vertically clamp one end of the workpiece 18. The second shaft hole positioning cylinder 12, in conjunction with the shaft hole positioning seat 13, vertically clamps the other end of the workpiece 18. At the same time, the first shaft hole positioning cylinder 10 vertically clamps the middle part of the workpiece 18.

[0043] At the same time, each lever cylinder 9 is activated, and through the lever structure inside each lever cylinder 9, the workpiece 18 is tightly fixed to the surface of the vertical plate 3, thereby achieving horizontal clamping of the workpiece 18.

[0044] Then, in the subsequent processing, the fixture and the fixed workpiece 18 move in all directions with the rotary table in the horizontal machining center, and further complete the processing of the workpiece 18.

[0045] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
