Each set of workpiece positioning and clamping assemblies includes a support base, two clamping devices, a V-shaped fixed positioning block, a V-shaped sliding positioning block, and at least one grooved positioning block. The support base is a convex shape with a higher center and lower sides. The two clamping devices are located on the sides of the support base and correspond to the left and right sides of the support base, respectively. The V-shaped fixed positioning block and the V-shaped sliding positioning block are respectively disposed at the left and right ends of the support base with their openings facing inward, for clamping the left and right ends of the workpiece. The V-shaped fixed positioning block is fixed to the support base, and the V-shaped sliding positioning block is slidably connected to the support base. The grooved positioning block has a groove in the middle that matches the width of the workpiece and is disposed on the lower left and right sides of the support base.

[0006] Furthermore, the support base is provided with anti-misalignment positioning blocks at both the front and rear of the middle high point, and the two anti-misalignment positioning blocks are used to position the straight part in the middle of the workpiece.

[0007] Furthermore, the clamping device includes a hydraulic lever cylinder and a pressure plate. The hydraulic lever cylinder is connected to the base plate and drives the pressure plate to clamp the arc-shaped portions on both sides of the workpiece through a lever mechanism.

[0008] Furthermore, a handle is provided on the outer side of the V-shaped sliding positioning block, and the V-shaped sliding positioning block is moved by the handle.

[0009] Furthermore, there are two groove positioning blocks, which are arranged in a straight line on the left and right low sides of the support base.

[0010] Furthermore, each pair of workpiece positioning and clamping components constitutes a pair, and the workpiece positioning and clamping components in each pair are arranged symmetrically relative to each other. Multiple pairs of workpiece positioning and clamping components are provided on the base plate.

[0011] Furthermore, the substrate is also provided with lifting rings for hoisting.

[0012] The beneficial effects of this utility model.

[0013] This invention utilizes a convex-shaped support base to provide three-point rigid support for the workpiece bottom. Multiple positioning blocks are combined for positioning, effectively addressing issues arising from thin-walled, easily deformable workpieces and variations in the blank's dimensions, ensuring the stability of the dimensions around the machined holes. Anti-misinstallation positioning blocks on the workpiece side effectively prevent incorrect installation, reducing quality risks. A hydraulic lever cylinder is used for clamping, ensuring sufficient and stable clamping force during processing. By setting multiple positioning and clamping components on the base plate, a single tooling fixture can complete multi-station production, significantly improving processing efficiency. Workpiece installation is simple and quick, reducing labor intensity. Attached Figure Description

Detailed Implementation

[0019] As shown in the accompanying drawings, this embodiment provides a hydraulic tooling for bearing covers, including a base plate 1. The base plate 1 is also provided with a lifting ring 10 for lifting. The base plate 1 is provided with four sets of workpiece positioning and clamping assemblies. Each pair of positioning and clamping assemblies forms a pair and is arranged symmetrically. The two pairs of positioning and clamping assemblies are arranged on the left and right sides of the base plate 1. One set of tooling constitutes four workstations, which improves processing efficiency.

[0020] Each workpiece positioning and clamping assembly includes a support base 2, two clamping devices, a V-shaped fixed positioning block 3, a V-shaped sliding positioning block 4, two grooved positioning blocks 5, and two anti-misalignment positioning blocks 6.

[0021] The support base 2 is a convex shape with a high center and low sides, which is used to match the shape of the corresponding flat center and rounded sides of the workpiece 11. While supporting the workpiece 11, it can also provide rigid support and positioning for the three points at the bottom of the workpiece 11.

[0022] Two clamping devices are located on the side of the support base 2 and correspond to the left and right sides of the support base 2 respectively. The clamping devices include a hydraulic lever cylinder 7 and a pressure plate 8. The hydraulic lever cylinder 7 is connected to the base plate 1 and drives the pressure plate 8 to clamp the two arc-shaped parts of the workpiece 11 through the lever mechanism.

[0023] V-shaped fixed positioning block 3 and V-shaped sliding positioning block 4 are respectively set at the left and right ends of the support base 2 with their openings facing inward, and are used to clamp the left and right ends of the workpiece 11. V-shaped fixed positioning block 3 is fixed to the support base 2, and V-shaped sliding positioning block 4 is slidably connected to the support base 2. A handle 9 is provided on the outside of V-shaped sliding positioning block 4, and V-shaped sliding positioning block 4 can be moved by the handle 9.

[0024] The connection between the V-shaped sliding positioning block 4 and the support base 2 can be in the form of a sliding pair consisting of a guide block and a guide rail, or it can be connected to the support base 2 through a structure that can pull the V-shaped sliding positioning block 4 and elastically reset it. It should be emphasized that the relative connection between the two is not limited to the form described, but is only used as an example. Since the relative sliding connection structure is very common in the prior art, the specific structure will not be described here. Any structure that can achieve relative sliding is acceptable.

[0025] The slidable V-shaped sliding positioning block 4 facilitates the loading and unloading of the workpiece 11. When installing the workpiece 11, the operator slides the V-shaped sliding positioning block 4 backward by hand, placing the outer arc wall of one side of the workpiece 11 into the V-groove of the V-shaped fixed positioning block 3. Then, the V-shaped sliding positioning block 4 is reset so that the V-groove of the V-shaped sliding positioning block 4 corresponds to the outer arc wall of the other side of the workpiece 11, and together with the V-shaped fixed positioning block 3, the end of the workpiece 11 is positioned.

[0026] The groove positioning block 5 has a groove in the middle that matches the width of the workpiece 11. The two groove positioning blocks 5 are arranged in a straight line on the left and right low sides of the support base 2, respectively, to position the two arc-shaped parts of the workpiece 11 in the groove.

[0027] Two anti-misalignment positioning blocks 6 are respectively set at the front and rear of the middle high position of the support base 2. The two anti-misalignment positioning blocks 6 are used to position the straight part in the middle of the workpiece 11 to prevent the workpiece 11 from being misaligned and improve the processing quality.

[0028] The general workflow is as follows: 1. The operator holds workpiece 11 and slides the V-shaped sliding positioning block 4 backward.

[0029] 2. Place the workpiece 11 on the support base 2, ensuring that the straight part in the middle of the workpiece 11 is located between the two anti-misalignment positioning blocks 6, the arc-shaped parts on both sides are stuck in the groove of the groove positioning block 5, and the arc-shaped outer wall at one end is placed in the V-shaped groove of the V-shaped fixing positioning block 3.

[0030] 3. The operator resets the V-shaped sliding positioning block 4 so that the V-shaped groove of the V-shaped sliding positioning block 4 corresponds to the outer arc wall of the workpiece 11 on the other side. The V-shaped sliding positioning block 4 and the V-shaped fixed positioning block 3 together clamp the two ends of the workpiece 11.

[0031] 4. Start the clamping device. The hydraulic lever cylinder 7 drives the pressure plate 8 to clamp the two arc parts of the workpiece 11.

[0032] 5. Ensure that workpiece 11 is correctly positioned and clamped before starting the processing operation.

[0033] It is understood that the above specific description of this utility model is only used to illustrate this utility model and is not limited to the technical solutions described in the embodiments of this utility model. Those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model to achieve the same technical effect; as long as the use needs are met, they are all within the protection scope of this utility model.
