Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and more specifically, to a part fixing fixture for a multi-station drilling machine. Background Technology

[0002] In existing small-scale drilling operations for pump bodies, fixtures are needed to hold the pump body in place so that the drill bit can proceed. Traditional pump body fixtures are typically designed for a single pump type, meaning a custom fixture is designed for each pump type to hold the pump and complete the drilling operation. Only one set of fixtures is designed for each drilling machine, requiring frequent loading and unloading during drilling operations, increasing the workload of workers. When processing a different type or specification of pump, the machine must be stopped, the original fixture removed, and a new fixture installed and adjusted. This results in high fixture setup and production costs, low fixture utilization, and long production preparation and speed adjustment intervals, making it difficult to meet the production demands of high-frequency drilling. Furthermore, for small-batch, multi-variety production orders, a dedicated fixture needs to be designed for each workpiece, leading to extremely high design, production, and management costs. Therefore, a parts fixing fixture for multi-station drilling machines is proposed. Utility Model Content

Detailed Implementation

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] See Figures 1 to 6This utility model provides a part fixing fixture for a multi-station drilling machine, suitable for installation on the drilling machine panel. It includes a drilling ring 1, a fixture assembly 3, and a rotating disk 2. The drilling ring 1 is disposed at the outer end of the rotating disk 2, and the inner end face of the drilling ring 1 is welded to the outer end face of the rotating disk 2. Multiple sets of fixture assemblies 3 are equidistantly arranged on the panel of the drilling ring 1. The fixture assembly 3 includes an adjusting frame 33, and an I-beam 35 is provided on the adjusting frame 33. A set of movable blocks 36 are respectively sleeved at both ends of the I-beam 35. A set of movable clamps 34 are respectively provided on the movable blocks 36. When the movable blocks 36 are subjected to force, the movable clamps 34 move relative to or away from each other on the I-beam 35, changing the distance between the two sets of movable clamps 34.

[0028] In this embodiment, the distance between the two sets of movable clamps 34 is adjusted by the lifting displacement of multiple sets of rotating adjustment frames 37 and cylinder extension rod 313. The cylinder body 314 is controlled by the solenoid valve signal controlled by the work command to adjust the extension amount of the cylinder extension rod 313, thereby changing the specific extension amount of the cylinder extension rod 313, adjusting the specific position of the lifting block 310, controlling the two sets of movable clamps 34 to run relative to or opposite to each other on the I-beam frame 35, changing the distance between the two sets of movable clamps 34, thereby realizing the abutment clamping or release of the workpiece.

[0029] The drill press panel restricts the installation of the part fixing fixture, including the drilling ring 1. The entire part fixing fixture rotates on the drill press panel at a specific amplitude and frequency, moving the workpiece to be drilled, which is fixed and abutted on each set of fixture components 3, to the bottom of the drilling device to complete the drilling process. The workpiece fixed on the fixture components 3 does not produce angular displacement. The drill bit mounting bracket is designed with an adjustment device. If it is necessary to drill at different positions on the upper end face of the workpiece, the working position of the drill bit can be adjusted.

[0030] See Figures 3 to 6 On the adjusting frame 33, a set of fixing pins 39 are provided at each of the two sets of movable blocks 36. On each side of the adjusting frame 33, a set of rotating adjusting frames 37 are provided. The rotating adjusting frames 37 are designed with a bent structure. On the same set of fixing pins 39, the two sets of rotating adjusting frames 37 are provided at each of the movable blocks 36 with a set of first adjusting grooves. A set of first adjusting pins 38 are provided in the adjusting grooves on the same side. A set of fixing pins 39 are provided at each end of the adjusting frame 33. Each set of fixing pins 39 is rotatably connected to the two sets of rotating adjusting frames 37 on the same side. The rotating adjusting frames 37 on the same side are slidably connected to the first adjusting pins 38 through their respective first adjusting grooves. That is, under the support of the lifting block 310, the rotating adjusting frame 37 rotates at a certain angle with the connection point with the fixing pin 39 as the fulcrum. The first adjusting grooves all rotate with the rotating adjusting frame 37. The first adjusting pins 38 are always in the first adjusting grooves, thereby changing the positional relationship of the first adjusting pins 38.

[0031] Two sets of rotating adjustment frames 37 on the same set of fixed pins 39 are respectively provided with a set of second adjustment slots 312 at the ends away from the first adjustment slot. A set of second adjustment pins 311 are respectively provided in the second adjustment slots 312 on the same side. The second adjustment pins 311 are slidably connected to the second adjustment slots 312. The second adjustment pins 311 are all fixedly connected to the lifting block 310. The two sets of second adjustment slots on the two sets of rotating adjustment frames 37 on the same side are simultaneously slidably connected to a set of second adjustment pins 311. That is, the lifting block 310 drives the second adjustment pins 311 to move vertically, change the position of the second adjustment pins 311 in the second adjustment slots 312, and drive the rotating adjustment frame 37 to rotate a certain angle on the fixed pins 39, so as to adjust the position of the two sets of movable clamps 34 on the I-beam frame 35, change the distance between the two sets of movable clamps 34, and adapt to the limited installation of workpieces of different specifications to be drilled.

[0032] The fixed pin 39 is fixed at both ends and is installed on the rotating adjustment frame 37 by fixed ends. The rotating adjustment frame 37 can generate angular displacement on the fixed pin 39, but will not generate linear displacement on the fixed pin 39. That is, the rotating adjustment frame 37 will not come off the fixed pin 39. Under the lifting action of the lifting block 310, it simultaneously supports the two sets of second adjustment pins 311 to generate vertical displacement, thereby changing the spacing between the structures at the end of the rotating adjustment frame 37 where the first adjustment groove is set.

[0033] The movable fixture 34 and the movable block 36 are integrally formed. The height and width of the movable fixture 34 are not limited. The first adjusting pin 38 is provided with movable connecting ends on both sides of the first adjusting groove. The first adjusting pin 38 is limited to the connection with the first adjusting groove through the two sets of movable connecting ends. That is, the rod of the first adjusting pin 38 can slide in the first adjusting groove, and the first adjusting pin 38 will not come out of the first adjusting groove. The rotation of the adjusting frame 37 causes the first adjusting pin 38 to drive the movable block 36 to move relative to or away from each other on the I-beam frame 35, thereby changing the distance between the movable fixtures 34 to adapt to the fixed and limited use of workpieces with different diameters and lengths.

[0034] A cylinder body 314 is provided below the lifting block 310. A cylinder extension rod 313 is provided at the extended end of the cylinder body 314. The cylinder extension rod 313 is fixedly connected to the middle of the bottom of the lifting block 310. A mounting panel is provided at the top of the cylinder body 314. The mounting panel is fixedly connected to the drilling ring 1. That is, the connection of the cylinder body 314 is fixed by the drilling ring 1. The extension and retraction of the cylinder extension rod 313 does not affect the installation position of the cylinder body 314, but only controls the moving direction and displacement of the lifting block 310. In this embodiment, the cylinder body 314 receives the output signal from the control terminal to the solenoid valve to control the specific extension amount of the cylinder extension rod 313, thereby adjusting the distance between the two sets of movable clamps 34.

[0035] See Figure 5The I-beam frame 35 has a notch in the center, and a connecting seat 315 is provided in the notch. A pump body bottom support 316 is provided on the connecting seat 315. The connecting seat 315 is set on the clamp assembly 3 and is located in the center of the two sets of movable clamps 34. It supports the installation of the pump body bottom support 316. The pump body bottom support 316 provides support for the bottom of the workpiece to be drilled, and accurately displays the upper end face of the workpiece below the suspension device.

[0036] The pump body bottom bracket 316 is fixedly installed with the connecting seat 315 by positioning pins. Different widths or heights of pump body bottom brackets 316 can be set on the connecting seat 315 according to the specific usage requirements of the workpiece, so as to adapt to the bottom inner cavity of workpieces with different inner diameters and complete the support and limit.

[0037] The bottom of the connecting seat 315 is provided with four sets of columns that are connected to the fixture setting panel 32. The bottom sides of the fixture setting panel 32 are provided with a set of support legs 31. The support legs 31 are all fixedly connected to the drilling ring 1. That is, the entire fixture assembly is fixed through the drilling ring 1 to establish drilling support. The number and spacing of the fixture components 3 on the drilling ring 1 can be designed according to the drilling requirements to adapt to drilling machines and drilling processing with different drilling requirements. The fixture setting panel 32 supports the installation of the connecting seat 315 and the adjusting stand 33, and confines the fixture tooling within the vertical space of the fixture setting panel 32.

[0038] See Figure 2 A reduction gearbox 4 is located at the center of the bottom of the rotating disk 2. A servo motor 5 is located at the input end of the reduction gearbox 4. The specific output speed of the servo motor 5 is adjusted by the reduction gearbox 4 so that the rotating disk 2 can drive the drilling ring 1 to achieve precise rotation, avoiding over-rotation or under-rotation, and ensuring the accuracy of drilling operations.

[0039] The drilling machine panel has a circular groove, and the drilling ring 1 is rotatably installed in the circular groove. The bottom of the circular groove has a protruding edge, and there is a gap of 0.2mm-0.5mm between the protruding edge and the bottom panel of the drilling ring 1. The protruding edge of the circular groove is close to the cylinder body 314, which provides support for the drill bit operation without restricting the movement of the cylinder body 314. The drilling machine panel is designed with a circular groove to accommodate the installation of the drilling ring 1. That is, the servo motor 5 controls the rotating disk 2 to rotate through the reduction gearbox 4, so as to drive the drilling ring 1 to rotate in the circular groove.

[0040] The tilting gap caused by the sinking of the outer end of the drilling ring 1 due to pressure is compensated by the inward and outward tilting of the connecting seat 315 and the pump body bottom bracket 316, so as to ensure that the drilling plane and the drilling device can be aligned to complete the drilling process.

[0041] A set of proximity signal reflectors 6 are respectively provided at the center of the clamping assembly 3 along the edge of the drilling ring 1. A proximity sensor is provided at the corresponding position of the drilling device in the circular groove. The signal emitted by the proximity sensor in the circular groove is received by the proximity signal reflector 6 and reflected back to the proximity sensor, thereby determining whether the clamping assembly 3 is in place and facilitating the judgment of whether the drill bit has sunk.

[0042] This utility model provides a multi-station drilling machine parts fixing fixture, which is installed on the drilling machine as a whole, with each set of fixture components 3 extending out of the drilling machine panel. The cylinder body 314 drives the cylinder extension rod 313 to move downward, and through multiple sets of rotating adjustment frames 37, drives two sets of movable fixtures 34 to move in opposite directions at the same time, so that the worker can place the workpiece on the connecting seat 315. Then, the cylinder body 314 drives the cylinder extension rod 313 to move upward, and the two sets of movable fixtures 34 move relative to each other at the same time, abutting against the connection of the workpiece. After a set of workpieces is placed on each set of fixture components 3, the worker leaves the drilling machine area. The servo motor 5 drives the drilling ring 1 to rotate at a certain frequency through the reduction gearbox 4, moving the fixture component 3 with the workpiece placed to below the drilling device. Upon receiving the signal that the workpiece is in place, the workpiece is directly drilled according to the preset program.

[0043] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
