Description

Technical Field

[0001] This utility model belongs to the technical field of alloy steel pump heads, and specifically relates to a multi-station rapid processing device for alloy steel pump head bodies. Background Technology

[0002] As a key component in petroleum machinery, the alloy steel pump head body has a complex structure and requires multiple processing steps such as rough milling, fine boring, drilling, and polishing, which places extremely high demands on processing accuracy and efficiency.

[0003] Existing technologies for processing alloy steel pump heads mostly employ a single-station processing mode, where a new workpiece is replaced only after all processes are completed on a single workpiece. This results in long equipment downtime, low processing efficiency, and difficulty in meeting the demands of mass production. Utility Model Content

[0004] This utility model addresses the problems of existing technologies by providing a multi-station rapid processing device for alloy steel pump heads. The specific technical solution is as follows:

[0005] A multi-station rapid machining device for alloy steel pump head bodies includes:

[0006] The main body has multiple workstations distributed circumferentially on it;

[0007] and an adjustment assembly mounted on the body, the adjustment assembly comprising:

[0008] A rotating shaft is rotatably located at the center of the main body;

[0009] A mounting bracket is installed on the rotating shaft, one end of which extends toward the edge of the body;

[0010] And a tray provided at the extension end of the fixed frame, on which the workpiece is placed;

[0011] The rotation of the shaft allows the workpiece to be moved between multiple workstations.

[0012] As a further technical solution of this utility model, the following is provided between the tray and the fixing frame:

[0013] The output motor is located below the tray;

[0014] And the connecting shaft that connects the output end of the output motor to the center of the tray;

[0015] The output motor can drive the tray to rotate to adjust the workpiece posture.

[0016] As a further technical solution of this utility model, the fixing frame is also provided with:

[0017] A slide rail extending along the trajectory of the fixed frame;

[0018] A sliding plate is set within a slide rail, and the output motor is mounted on the sliding plate;

[0019] A drive cylinder mounted on a fixed frame, the output end of which is rotatably connected to a connecting shaft;

[0020] The drive cylinder can drive the slide plate to move to adjust the distance between the workpiece and the workstation.

[0021] As a further technical solution of this utility model, a fan-shaped counterweight is also provided on the opposite side of the extended end of the fixing frame.

[0022] As a further technical solution of this utility model, the main body includes a workbench and a support member. Multiple workstations are set on the workbench, and multiple sets of support members are arranged along the shape trajectory of the workbench at the bottom of the workbench.

[0023] The beneficial effects of this utility model are as follows:

[0024] (1) Multiple workstations are distributed along the circumference of the worktable and are combined with an adjustment component with the center of the body as the rotation axis to form a “concentric circle processing unit”; the workpiece can be quickly switched between workstations at 360° by rotating the shaft.

[0025] (2) The adjustment component achieves precise positioning of the workpiece's circumferential motion through the rigid connection of "rotating shaft-fixed frame-pallet". The extended length design of the fixed frame ensures that the pallet trajectory covers all workstations. Combined with the pallet's self-rotation and radial translation functions, it forms a three-in-one adjustment mechanism of "rotational transfer + posture adjustment + distance adaptation".

[0031] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0032] Figure 1 A schematic diagram of the overall structure of a multi-station rapid processing device for alloy steel pump head body is shown. Figure 2 A schematic diagram of the structure of the main body 100 is shown; Figure 3 A schematic diagram of the adjustment component 200 is shown.

[0033] Figure 1 and Figure 2 The multi-station rapid processing device for alloy steel pump head includes a body 100 and an adjustment component 200 installed on the body 100. The body 100 includes a worktable 110 and a support member 120. The worktable 110 has multiple stations 111 distributed circumferentially. Multiple sets of support members 120 are arranged at the bottom of the worktable 110 along the shape trajectory of the worktable 110.

[0034] The circumferentially distributed workstations 111 can simultaneously carry multiple workpieces for processing in different processes, forming a "parallel processing flow". The transfer function of the adjustment component 200 is used to achieve process connection. Multiple sets of support components 120 are distributed along the trajectory of the worktable 110. The vibration and torque generated during processing are offset by the uniform force at multiple points, which avoids the worktable 110 from being deformed by local force and affecting the processing accuracy. Compared with the traditional single-station processing device, the equipment utilization rate is higher, and roughing, finishing and inspection processes can be completed simultaneously.

[0035] Figure 3 In the middle, the adjustment component 200 includes:

[0036] A rotating shaft 210 is rotatably set at the center of the main body 100. In actual use, a motor can be installed on the main body 100 and the output end of the motor can be connected to the rotating shaft 210 to achieve controllable automatic rotation.

[0037] A mounting bracket 220 is installed on the rotating shaft 210, with one end of the mounting bracket 220 extending toward the edge of the body 100; by approaching the edge of the body 100 through this extended end, all the worktables 110 on the body 100 can be covered as the rotating shaft 210 rotates.

[0038] The workpiece is placed on a tray 230 at the extension end of the fixed frame 220; the workpiece moves synchronously with the tray 230 to achieve a change in position.

[0039] The rotation of the shaft 210 allows the workpiece to be changed between multiple workstations 111; when the shaft 210 rotates, the fixed frame 220 and the tray 230 located at the extension end of the fixed frame 220 rotate synchronously, so that the tray 230 can be changed between multiple workstations 111 on the body 100.

[0040] The rotating shaft 210 is driven by a motor to achieve 360° controllable rotation, which drives the fixed frame 220 and the pallet 230 to perform circular motion. The extended length design of the fixed frame 220 ensures that the movement trajectory of the pallet 230 covers all workstations 111. When the rotating shaft 210 rotates to the specified angle, the pallet 230 accurately docks with the target workstation, realizing "non-stop transfer" of the workpiece, reducing the workpiece handling path and reducing positioning errors caused by multiple loading and unloading.

[0041] See also Figure 3 A connection is provided between the tray 230 and the fixing bracket 220:

[0042] An output motor 240 is located below the tray 230;

[0043] and the connecting shaft 250 connecting the output end of the output motor 240 and the center of the tray 230;

[0044] The output motor 240 can drive the tray 230 to rotate to adjust the workpiece posture; the output motor 240 and the connecting shaft 250 are used to realize the rotation of the tray 230 so that the workpiece located on the tray 230 can adjust its own posture.

[0045] The output motor 240 transmits torque to the tray 230 via the connecting shaft 250, achieving stepless speed regulation and self-rotation from 0-360°. The center connection between the connecting shaft 250 and the tray 230 ensures concentricity of rotation and prevents workpiece offset. When the workpiece needs to be machined on different sides, such as holes, planes, and curved surfaces of the pump head, the motor can precisely control the rotation angle and work with the machining tools at station 111 to complete multi-face machining. This breaks through the traditional machining mode of "fixed workpiece and moving tool" and achieves multi-face machining through workpiece rotation, reducing the number of tool adjustments.

[0046] See also Figure 3 A fan-shaped counterweight 221 is also provided on the opposite side of the extended end of the fixing frame 220.

[0047] The opposite side here refers to the side relative to the rotation center. The mass of the sector counterweight 221 is calculated based on the total mass of the extension end of the fixed frame 220, the tray 230 and the workpiece. The sector counterweight 221 is used to balance the weight on both sides of the rotation center. The centrifugal force generated during rotation is offset by symmetrical distribution, thereby reducing the vibration of the rotating mechanism caused by "center of gravity offset".

[0048] See also Figure 3 The mounting bracket 220 is also equipped with:

[0049] A slide 260 is opened along the extended trajectory of the fixed frame 220;

[0050] A sliding plate 270 is set within a slide rail 260, and an output motor 240 is mounted on the sliding plate 270.

[0051] And a drive cylinder 280 mounted on a fixed frame 220, the output end of the drive cylinder 280 being rotatably connected to a connecting shaft 250;

[0052] The drive cylinder 280 can drive the slide plate 270 to move to adjust the distance between the workpiece and the station 111; the distance here refers to the radial distance.

[0053] The drive cylinder 280 uses pneumatic extension to drive the connecting shaft 250 and the slide plate 270 to move linearly along the slide rail 260, thereby adjusting the position of the pallet 230 in the radial direction. The radial distance adjustment ensures the optimal fit between the workpiece and the machining tool, and the rotational transfer achieves "dimensional adaptive machining". The rotational connection design between the cylinder output end and the connecting shaft 250 ensures that the pallet 230 is not interfered with by the cylinder when it rotates.

[0054] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
