Description

Technical Field

[0001] This utility model relates to the field of bearing housing assembly technology, and in particular to a multi-station bearing housing processing and fixing fixture. Background Technology

[0002] Bearing housings are key mechanical components used to support and secure bearings, playing an indispensable role in various rotating machinery systems.

[0003] In existing technologies, when machining bearing housings, a chuck driven by a hydraulic cylinder is used to hold the bearing housing in the corresponding working position to ensure accurate and stable positioning of the bearing housing during machining. However, chuck fixtures have the following disadvantages:

[0004] (1) In order to ensure clamping stability, the contact area between the chuck and the outer wall of the bearing housing is large, which can easily cause machining interference and reduce the convenience of machining operation;

[0005] (2) The chuck can only provide a single radial clamping action, which cannot counteract the torque generated by the cutting force, and is likely to cause the workpiece to vibrate or shift, affecting the machining accuracy.

[0006] (3) A chuck can only fix one bearing seat. In the processing flow, the next bearing seat can only be processed after the current bearing seat is processed and unloaded, resulting in low processing efficiency. Utility Model Content

[0007] Therefore, it is necessary to provide a multi-station bearing housing machining fixture to address the problems of poor machining operation convenience, low machining accuracy, and low machining efficiency in the existing technology of machining bearing housings.

[0008] The technical solution adopted in this utility model is as follows:

[0009] A multi-station bearing housing machining fixture includes a transverse adjustment mechanism. The top and bottom of the transverse adjustment mechanism are respectively provided with several movable working positions. Limiting components are installed on each movable working position. A single set of limiting components includes at least four limiting mechanisms.

[0010] The structure of a single limiting mechanism is as follows: it includes a mounting column fixed on the movable working position, a first hinge seat is fitted on the top of the mounting column, the first hinge seat is hinged to the cylinder body of the cylinder through a first pin, and a limiting plate is hinged to the output end of the cylinder.

[0011] When a workpiece is placed on a single active workstation, the corresponding cylinder extends simultaneously, thereby driving the corresponding limit plate to approach the workpiece, and thus press and / or clamp the workpiece; when the corresponding cylinder retracts simultaneously, it drives the corresponding limit plate to leave the workpiece, thereby releasing the workpiece.

[0012] As a further improvement to the above technical solution:

[0013] In a single limiting mechanism, the mounting column is connected to the output end of a rotary motor. The mounting column rotates under the drive of the rotary motor, thereby causing the limiting plate to rotate.

[0014] In a single limiting mechanism, the limiting plate is a square plate or a triangular plate.

[0015] In a single limiting mechanism, the end face of the limiting plate that is in contact with the workpiece is provided with a concave arc surface.

[0016] In a single limiting mechanism, at least two limiting rods are fixed at intervals on the top of the limiting plate, with each limiting rod arranged vertically.

[0017] The structure of the transverse adjustment mechanism is as follows: it includes a mounting base, and transverse drive components are respectively installed on the top and bottom of the mounting base. Each transverse drive component includes slide modules arranged at intervals along the width direction of the mounting base. Several worktables are installed on a single slide module. A single worktable performs horizontal reciprocating linear motion under the drive of the corresponding slide module, thereby forming a corresponding active working position. A groove for placing workpieces is opened on the working end face of a single worktable.

[0018] For a single workbench, a sliding groove is provided on the end face opposite to the working end face.

[0019] The settling tank can be a square tank or a circular tank.

[0020] The mounting base is provided with several partition plates, which separate two adjacent worktables mounted on the same slide module.

[0021] A rotating shaft is installed in the middle of the transverse adjustment mechanism. The rotating shaft is arranged along the length of the transverse adjustment mechanism and is rotatably mounted on the support base. One end of the rotating shaft is connected to the output end of the drive motor. The drive motor drives the rotating shaft to rotate, thereby driving the transverse adjustment mechanism to rotate.

[0022] Robotic arm assemblies are arranged on both sides of the transverse adjustment mechanism. Each robotic arm assembly includes several robotic arms, and the robotic arms are arranged in a one-to-one correspondence with the movable work positions.

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

[0024] This utility model has a compact and reasonable structure and is easy to operate. By setting a transverse adjustment mechanism and a limiting mechanism, it can uniformly and stably limit and fix the workpiece, thereby improving the machining accuracy. Furthermore, by setting multiple limiting mechanisms to limit the workpiece in segments, it can effectively reduce the contact area between a single limiting mechanism and the workpiece, avoiding machining interference problems. In addition, the transverse adjustment mechanism is provided with multiple movable working positions, so that multiple workpieces can be limited based on a single transverse adjustment mechanism, thereby improving machining efficiency.

[0025] This utility model also has the following advantages:

[0026] (1) By setting a drive motor and mounting column, this utility model can drive the limit plate to rotate, so that the limit plate leaves the corresponding sink when the bearing seat is loaded or unloaded, thereby avoiding the bearing seat during loading or unloading, and ensuring the stability and continuity of the production process.

[0027] (2) In this utility model, the limiting plate is a square plate or a triangular plate, and the sink is a square sink or a round sink, which can match various types of bearing seats and improve the stability and compatibility of the device.

[0028] (3) By setting a limiting rod, the present invention can abut against the outer wall of the corresponding bearing seat when the limiting component clamps the corresponding bearing seat, thereby further limiting the clamping force of the component on the corresponding bearing seat; at the same time, auxiliary tooling can be assembled on the limiting rod for auxiliary limiting, effectively improving the flexibility of the use of the fixing fixture.

[0029] (4) By setting a sliding groove, this utility model can cooperate with the corresponding sliding module to improve the motion stability of the corresponding worktable.

[0030] (5) By setting a partition plate, this utility model can avoid collisions between two adjacent worktables during the movement driven by the corresponding sliding module. Attached Figure Description

[0041] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0042] The specific structure and function of this utility model are as follows:

[0043] like Figures 1-7 As shown, a multi-station bearing housing machining fixture includes a transverse adjustment mechanism 1. The top and bottom of the transverse adjustment mechanism 1 are respectively provided with several movable working positions. A limit assembly is installed on each movable working position, and a single limit assembly includes at least four limit mechanisms 2. The structure of a single limit mechanism 2 is as follows: it includes a mounting column 201 fixed to the movable working position. A first hinge seat 206 is installed on the top of the mounting column 201. The first hinge seat 206 is hinged to the cylinder body of a cylinder 202 via a first pin 207. A limit plate 203 is hinged to the output end of the cylinder 202. When a workpiece is placed on a single movable working position, the corresponding cylinder 202 extends simultaneously, thereby driving the corresponding limit plate 203 to approach the workpiece, thereby pressing and / or clamping the workpiece. When the corresponding cylinder 202 retracts simultaneously, it drives the corresponding limit plate 203 away from the workpiece, thereby releasing the workpiece. In this invention, the workpiece is a bearing housing. By setting a transverse adjustment mechanism 1 and a limiting mechanism 2, the bearing housing can be clamped evenly and stably during machining. At the same time, one fixed fixture can process multiple bearing housings simultaneously, achieving high-precision and high-efficiency machining.

[0044] In this utility model, the output end of the cylinder 202 is connected to a connector 205, and a second hinge seat 208 is fixed on the limiting plate 203. The second hinge seat 208 is hinged to the connector 205 through a second pin 209, thereby realizing the hinge connection between the limiting plate 203 and the output end of the cylinder 202.

[0045] In a single limiting mechanism 2, the mounting column 201 is connected to the output end of a rotary motor. The mounting column 201 rotates under the drive of the rotary motor, thereby causing the limiting plate 203 to rotate. In this utility model, the limiting mechanism 2 has a rotation function. By driving the limiting plate 203 to rotate through a rotary motor (not shown in the attached drawings), the limiting plate 203 is moved away from the corresponding groove 104 in the transverse adjustment mechanism 1 when the bearing seat is being loaded or unloaded, thereby avoiding obstruction during the loading or unloading of the bearing seat and ensuring the stable and continuous production process.

[0046] In a single limiting mechanism 2, the limiting plate 203 is a square plate or a triangular plate. Depending on the type of bearing housing being processed, a square plate or a triangular plate can be used to ensure that the limiting plate 203 limits the corresponding bearing housing, thereby improving the stability and compatibility of the device.

[0047] In a single limiting mechanism 2, the end face of the limiting plate 203 that contacts the workpiece is provided with a concave arc surface. By providing the concave arc surface, it can conform to the shape of the outer wall surface of the corresponding type of bearing seat, thereby improving the clamping force of the limiting component on the corresponding bearing seat.

[0048] In a single limiting mechanism 2, at least two limiting rods 204 are fixedly spaced at the top of the limiting plate 203, with each limiting rod 204 arranged vertically. By setting the limiting rods 204, they can abut against the outer wall of the corresponding bearing seat when the limiting component clamps the corresponding bearing seat, thereby further limiting the clamping force of the component on the corresponding bearing seat; at the same time, auxiliary tooling can be assembled on the limiting rods 204 for auxiliary limiting, effectively improving the flexibility of the fixed fixture.

[0049] The structure of the transverse adjustment mechanism 1 is as follows: it includes a mounting base 101, with transverse drive components mounted on the top and bottom of the mounting base 101. Each transverse drive component includes slide modules 102 spaced apart along the width direction of the mounting base 101. Several worktables 103 are mounted on each slide module 102. Each worktable 103 moves horizontally and reciprocally under the drive of the corresponding slide module 102, thereby forming a corresponding movable working position. A groove 104 for placing workpieces is provided on the working end face of each worktable 103. By setting the slide modules 102, the position of the corresponding worktable 103 can be adjusted within a certain range, thus facilitating the operation of the robotic arm 6 during its work.

[0050] For a single worktable 103, a slide groove 105 is provided on the end face opposite to the working end face. The slide groove 105 is used to cooperate with the corresponding slide module 102 to improve the motion stability of the corresponding worktable 103.

[0051] The countersink 104 can be square or circular. By setting different types of countersinks 104, various types of bearing housings can be matched, improving the compatibility of the device.

[0052] The mounting base 101 is provided with several partition plates 106, which separate two adjacent worktables 103 mounted on the same slide module 102. By setting the partition plates 106, collisions can be avoided between two adjacent worktables 103 during their movement driven by the corresponding slide module 102.

[0053] A rotating shaft 4 is installed in the middle of the transverse adjustment mechanism 1. The rotating shaft 4 is arranged along the length of the transverse adjustment mechanism 1 and is rotatably mounted on the support base 3. One end of the rotating shaft 4 is connected to the output end of the drive motor 5. The drive motor 5 drives the rotating shaft 4 to rotate, thereby driving the transverse adjustment mechanism 1 to rotate. Robotic arm assemblies are arranged on both sides of the transverse adjustment mechanism 1. A single robotic arm assembly includes several robotic arms 6, and the robotic arms 6 are arranged one-to-one with the movable work positions. By setting up a robotic arm 6, whose working end is equipped with a machining fixture, it is possible to perform machining on the bearing housing. The drive motor 5 and the rotating shaft 4 can drive the transverse adjustment mechanism 1 to rotate, thereby causing the bearing housing to flip during the machining operation of the robotic arm 6, so as to cooperate with the machining operation of the robotic arm 6 and improve the convenience of operation. At the same time, the top and bottom of the transverse adjustment mechanism 1 are provided with movable working positions. The drive motor 5 can drive the transverse adjustment mechanism 1 to flip over through the rotating shaft 4, so that after the workpiece on the top movable working position is processed, the workpiece on the bottom movable working position can be flipped over to process. During this process, there is no need to perform loading and unloading operations, which can effectively increase the processing volume per unit time and further improve the processing efficiency.

[0054] The working process of this utility model is as follows:

[0055] The fixing clamp of this utility model can limit different types of bearing seats by means of pressing and limiting, clamping and limiting, or a combination of pressing and clamping and limiting.

[0056] Specifically, when the clamping and limiting method is adopted, after the bearing seat of the corresponding type is placed in the corresponding sink 104, the edge of the bearing seat has a horizontal limiting surface that is flush with the corresponding worktable 103. After the rotary motor drives the limiting plate 203 to rotate into place, the corresponding cylinder 202 drives the limiting plate 203 to approach the corresponding horizontal limiting surface, so that the horizontal working surface of the limiting plate 203 fits with the horizontal limiting surface, thereby achieving the clamping and limiting of the corresponding bearing seat.

[0057] When the clamping and limiting method is adopted, after the rotary motor drives the limiting plate 203 to rotate into place, the corresponding cylinder 202 drives the limiting plate 203 to approach the outer wall of the corresponding bearing seat, so that the lateral working surface of the limiting plate 203 fits against the outer wall of the bearing seat, thereby achieving the clamping and limiting of the corresponding bearing seat.

[0058] When a combined pressing and clamping limiting method is used, after the cylinder 202 drives the corresponding limiting plate 203 to move into place, the lateral working surface and the horizontal working surface of the limiting plate 203 simultaneously fit with the corresponding limiting plate 203, thereby achieving the limiting of the bearing seat.

[0059] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
