Description

Technical Field

[0001] This utility model relates to the field of press-fitting equipment, and in particular to a workbench assembly for press-fitting fixtures. Background Technology

[0002] Press-fitting fixtures are specialized process equipment used to accurately, smoothly, and reliably press standard parts such as bearings, bushings, pins, and bushings into workpieces. They can be widely used in fields such as machinery manufacturing, automobile assembly, and motor production, ensuring assembly accuracy, improving production efficiency, and reducing human error and part damage.

[0003] Existing press fitting fixtures mostly use manual alignment to precisely align the center axis of the press head with the center axis of the mounting hole on the workpiece. Manual alignment not only results in high labor intensity and slow production speed, delaying production progress and reducing production output, but also easily causes inaccurate alignment, press head deviation, and consequently leads to problems such as tilted pressing of standard parts, damage to hole walls or parts, uneven pressing force, or decreased assembly accuracy. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings in the above-mentioned technology and provide a workbench assembly for press-fitting fixtures. Through the workbench assembly in this application, the base plate of the press-fitting fixture is standardized and zero-point positioning is used. On the basis of the original workbench, a shape-changing plate is added, and positioning parts are used to ensure accurate alignment. In this way, the center axis of the press head of the press-fitting fixture is quickly and accurately aligned with the center axis of the mounting hole on the workpiece being processed, reducing the intensity of the alignment work after changing the fixture and increasing the press-fitting production output.

[0005] The technical solution of the press-fitting fixture workbench assembly provided by this utility model is as follows:

[0006] A press tooling workbench assembly includes a press base plate and a tooling change plate for quick tooling change. The tooling change plate is located on the upper part of the press base plate and is provided with tooling stabilizing holes for installing corresponding project tooling. The tooling change plate is connected to the press base plate by a positioning component. The locking and positioning of the tooling change plate by the positioning component enables quick alignment of the tooling centerline with the press head centerline.

[0007] Furthermore, the positioning component includes a positioning sleeve and a ball lock shaft, the ball lock shaft being installed inside the positioning sleeve and detachably connected to the positioning sleeve.

[0008] Furthermore, one end of the positioning component is connected to the press base plate via a positioning sleeve, and the other end is connected to the positioning sleeve via a ball lock shaft through the forming plate, thereby fixing the forming plate to the press base plate.

[0009] Furthermore, the shape-changing plate is evenly provided with several positioning holes, the ball lock shaft and the positioning sleeve pass through the positioning holes, and the ball lock shaft and the positioning sleeve are threadedly connected.

[0010] Furthermore, the positioning sleeve is connected to the press base plate by fixing screws.

[0011] Furthermore, there are 6 to 10 positioning components.

[0012] Furthermore, it also includes a press base plate, which is located at the bottom of the press base plate and is connected to the press base plate by fasteners.

[0013] Furthermore, a pressure head is correspondingly provided above the tooling installed on the shape change plate. The pressure head includes a bottom cap and a pressure rod. The pressure rod is sleeved inside the bottom cap and is fastened by a fastener.

[0014] Furthermore, the press head is mounted on the upper plate of the press via a bottom cap, and the upper plate of the press is mounted on the bottom of the press head of the pressing fixture.

[0015] Compared with the prior art, the present invention has the following outstanding beneficial technical effects:

[0016] This application achieves rapid switching of tooling for different projects by setting a detachable and replaceable form change plate and connecting it with the positioning component on the press base plate. The tooling stabilizing holes on the form change plate facilitate the standardized installation of tooling, while the precise positioning of the form change plate by the positioning component ensures that the central axis of the tooling is automatically aligned with the central axis of the press head after each change, avoiding the tedious process of repeated adjustment and alignment in the traditional method, and significantly improving the form change efficiency and pressing accuracy.

[0017] By standardizing the base plate of the press-fitting fixture through the worktable assembly and using zero-point positioning, a change plate is added to the original worktable, and positioning components are used to ensure accurate alignment. This allows the center axis of the press head of the press-fitting fixture to be quickly and accurately aligned with the center axis of the mounting hole on the workpiece, reducing the intensity of the alignment work after changing the fixture and improving the speed and output of press-fitting production.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0034] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] As attached Figure 1-7As shown, a press tooling workbench assembly includes a press base plate 1 and a tooling change plate 2 for quick tooling change. The tooling change plate 2 is located on the upper part of the press base plate 1. The tooling change plate 2 is provided with tooling stabilizing holes 7 for installing corresponding project tooling. The tooling change plate 2 is connected to the press base plate 1 through a positioning member 3. The locking positioning of the tooling change plate 2 by the positioning member 3 achieves quick alignment of the tooling center axis with the center axis of the press head 4.

[0037] It is evident that by setting up a detachable and replaceable mold changing plate 2, and connecting it with the positioning component 3 on the press base plate 1, rapid switching between tooling for different projects can be achieved. The tooling stabilizing hole 7 on the mold changing plate 2 facilitates the standardized installation of tooling, while the precise positioning of the mold changing plate 2 by the positioning component 3 ensures that the central axis of the tooling is automatically aligned with the central axis of the press head 4 after each change, avoiding the tedious process of repeated adjustment and alignment in the traditional method, and significantly improving mold changing efficiency and pressing accuracy.

[0038] As an example of this application, see the attached document. Figure 6-7 As shown, the positioning component 3 includes a positioning sleeve 31 and a ball lock shaft 32. The ball lock shaft 32 is installed inside the positioning sleeve 31, and the ball lock shaft 32 is detachably connected to the positioning sleeve 31.

[0039] The positioning component structure, consisting of a positioning sleeve 31 and a ball-locking shaft 32, offers advantages such as reliable connection and convenient assembly / disassembly. The ball-locking shaft 32 can quickly extend and retract within the positioning sleeve 31, and its detachable connection facilitates maintenance and replacement while ensuring consistent positioning accuracy. The structural design of the positioning component 3 simplifies the installation and disassembly process of the shape-changing plate 2, enhances operational automation and safety, and reduces errors caused by manual intervention.

[0040] As an embodiment of this application, one end of the positioning member 3 is connected to the press base plate 1 through the positioning sleeve 31, and the other end is connected to the positioning sleeve 31 through the ball lock shaft 32, thereby fixing the positioning plate 2 on the press base plate 1.

[0041] Furthermore, the longitudinal section of the positioning sleeve 31 is T-shaped, and the press base plate 1 and the changing plate 2 are installed on the press base plate 6 at the bottom through the T-shaped structural design.

[0042] Specifically, the bottom of the positioning sleeve 31 is provided with several slots, in which fasteners can be installed and connected to the press base plate 1. Optional fasteners include one or more of bolts, screws, nuts, pins, and snap rings.

[0043] Preferably, the positioning sleeve 31 is connected to the press base plate 1 via fixing screws (such as bolts or screws). The connection between the positioning sleeve 31 and the press base plate 1 via fixing screws (such as bolts or screws) is simple in structure, easy to assemble and disassemble, and has high connection strength. This method facilitates the replacement or maintenance of the positioning sleeve 31, adapts to the needs of different specifications of the form change plate 2, and improves the flexibility and maintainability of the entire workbench assembly. At the same time, the connection of the fixing screws effectively transmits loads, ensuring the stability of the overall structure under high pressure.

[0044] Furthermore, there are 6 to 10 positioning components 3. The multiple positioning components 3 can ensure sufficient positioning rigidity and load-bearing capacity, while avoiding the increased cost and operational complexity caused by over-design. The multi-point evenly distributed positioning structure effectively disperses the force, improves the overall stability of the forming plate 2, and prevents warping or eccentricity. It is especially suitable for large or high-precision press-fitting conditions, ensuring that the tooling maintains precise alignment throughout the entire press-fitting process.

[0045] It should be noted that the connection between the positioning component 3 and the press base plate 1 and the forming plate 2 achieves integrated rigid fixation and high-precision positioning between the forming plate 2 and the press base plate 1. Specifically, the positioning sleeve 31 is fixed to the press base plate 1 to provide a reference, and the ball lock shaft 32 passes through the forming plate 2 and locks with the positioning sleeve 31. This not only ensures the stability of the forming plate 2 installation, but also achieves precise positioning through mechanical interference or clearance fit, effectively preventing displacement caused by vibration during the pressing process, and improving the consistency of the pressing operation and the product qualification rate.

[0046] Further details are attached. Figure 1-3 As shown, the shape-changing plate 2 is evenly provided with a number of positioning holes, the ball lock shaft 32 and the positioning sleeve 31 pass through the positioning holes, and the ball lock shaft 32 and the positioning sleeve 31 are threadedly connected.

[0047] As is easily understood, multiple evenly distributed positioning holes are provided on the shape change plate 2. These holes are used to install the positioning component 3. The threaded connection between the ball lock shaft 32 and the positioning sleeve 31 in the positioning component 3 enhances the connection's robustness and torsional resistance. The threaded connection provides a stable preload to prevent loosening, while a quick locking action is achieved through tightening. This multi-point positioning design further improves the flatness and coaxiality of the shape change plate 2 during installation, ensuring stable operation of the tooling under complex stress conditions.

[0048] Furthermore, the forming plate 2 is evenly provided with tooling stabilizing holes 7 for installing tooling to be press-fitted, and the central axis of the tooling is quickly aligned with the central axis of the press head 4.

[0049] As an example of this application, see the attached document. Figure 2As shown, the press fixture's workbench assembly also includes a press base plate 6, which is located at the bottom of the press base plate 1 and is connected to the press base plate 1 by fasteners.

[0050] The press base plate 6 is the bottom support component of the press fitting equipment. As an integral support foundation, it improves the structural rigidity and seismic resistance of the entire press fitting workbench. The press base plate 6 is connected to the press bottom plate 1 by fasteners, forming a stable multi-layer support system that effectively absorbs the impact and vibration during the press fitting process, reduces equipment deformation, and extends service life.

[0051] As an example of this application, a pressure head 4 is correspondingly provided above the tooling installed on the forming plate 2, as shown in the attached figure. Figure 2-5 The pressure head 4 includes a bottom cap 41 and a pressure rod 42. The pressure rod 42 is sleeved inside the bottom cap 41 and is fastened by a fastener.

[0052] Furthermore, the press head 4 is mounted on the upper plate 5 of the press via the bottom cap 41, and the upper plate 5 of the press is mounted on the bottom of the press head of the pressing fixture. The press head 4 is connected to the upper plate 5 of the press via the bottom cap 41, which realizes the clamping and positioning of the press head 4 and the press head, ensuring that the central axis of the press head 4 is consistent with the direction of movement of the press head, and avoiding the generation of off-center load or lateral force.

[0053] In the press-fitting fixture, a drive structure is also provided. The press head 4 is connected to the drive structure. Under the operation of the drive structure, the press head 4 moves downward. The central axis of the press head 4 corresponds vertically to the central axis of the fixture on the annular plate. The press head 4 contacts the fixture and generates downward pressure, thereby completing the pressing process of the fixture.

[0054] Compared with the prior art, the above embodiments of this utility model have the following beneficial technical effects:

[0055] This application achieves rapid switching of tooling for different projects by setting a detachable and replaceable changing plate 2 and connecting it with the positioning component 3 on the press base plate 1. The tooling stabilizing hole 7 on the changing plate 2 facilitates the standardized installation of tooling, while the precise positioning of the changing plate 2 by the positioning component 3 ensures that the central axis of the tooling is automatically aligned with the central axis of the press head 4 after each replacement, avoiding the tedious process of repeated adjustment and alignment in the traditional method, and significantly improving the changing efficiency and pressing accuracy.

[0056] By standardizing the base plate of the press-fitting fixture through the worktable assembly and using zero-point positioning, a change plate 2 is added to the original worktable, and positioning parts 3 are used to ensure accurate alignment. This allows the center axis of the press head 4 of the press-fitting fixture to be quickly and accurately aligned with the center axis of the mounting hole on the workpiece, reducing the intensity of the alignment work after changing the fixture and increasing the press-fitting production output.

Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model.
