Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to a catalyst support clamping and positioning tool. Background Art

[0002] Catalyst supports are widely used in many fields, with the main purpose of improving the efficiency, stability and applicability of catalysts.

[0003] In the tooling structure used in catalyst bracket processing, the clamping method mostly uses a cylinder to push the pressure plate to press it against the upper end surface of the bracket. Since the catalyst bracket structure is relatively complex, there are many pressing points, which requires multiple cylinders to be installed on the tooling plate.

[0004] However, due to the structural limitations of one end of the catalyst bracket, this end needs to be penetrated and inserted into the tooling table during installation to ensure reliable clamping. Therefore, a convex hole must be opened on the tooling table to accommodate the insertion of the end of the catalyst bracket. However, due to the limited size of the tooling table, it is difficult to set up more cylinders on the table to press the bracket in all directions. Utility Model Content

[0005] The technical problem to be solved by the present invention is: in order to overcome the deficiencies in the prior art, the present invention provides a catalyst support clamping and positioning tool, which realizes the positioning and clamping of the catalyst support by means of side pressing and front pressing.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a catalyst bracket clamping and positioning tool, which has a tooling table, a convex hole is opened at the left end of the tooling table, and a positioning seat is installed on the tooling table at the right end of the convex hole. The right end of the catalyst bracket is positioned on the positioning seat, and the left end of the catalyst bracket is stuck in the convex hole. A pressing assembly for pressing the catalyst bracket is installed on the tooling table, and the pressing assembly has a pressing plate that rotates and presses on the upper end face of the catalyst bracket; a pressing assembly for laterally pressing the left end of the catalyst bracket is installed on the bottom surface of the tooling table, and the pressing assembly has a push rod that moves laterally and presses on the inner side surface of the left end of the catalyst bracket.

[0007] Specifically, the clamping assembly includes a clamping cylinder, a support and a rocker arm. The clamping cylinder is fixed on the bottom surface of the tooling table, the support is fixed on the upper end surface of the tooling table, the upper end of the rocker arm is hinged to the middle part of the pressure plate, and the lower end of the rocker arm is hinged to the support. The clamping cylinder piston rod passes through the tooling table and is hinged to the rear end of the pressure plate. The clamping cylinder pushes the front end of the pressure plate to rotate and press it on the upper end surface of the catalyst bracket.

[0008] Furthermore, the pressing assembly includes a tightening cylinder, a push rod with a long waist hole at the lower end, and a screw. The tightening cylinder is installed on the bottom surface of the workbench, and the push rod can be rotatably arranged on the left side of the tightening cylinder. The right end of the screw is threadedly connected to the tightening cylinder. The rod body at the left end of the screw is gap-matched with the long waist hole at the lower end of the push rod. The cylindrical head at the left end of the screw fits into the left side of the push rod. When the piston rod of the tightening cylinder retracts, the push rod is pulled to rotate, so that the left side of the upper end of the push rod pushes the push rod to press on the inner side of the left end of the catalyst bracket.

[0009] Furthermore, in order to better promote the lateral movement of the push rod, a guide seat is provided under the convex hole of the workbench, and the guide seat includes a mounting plate and a guide block. The mounting plate is fixed to the bottom surface of the workbench, and the guide block is located at the left end of the mounting plate and protrudes into the convex hole of the workbench. A guide hole is opened in the center of the guide block, and the push rod passes through the mounting plate and the middle part of the push rod is movably connected to the mounting plate. The middle part of the push rod slides with the guide hole, and the right end of the push rod has a flange that fits with the left side of the upper end of the push rod when tightened. A reset spring sleeved on the push rod is provided between the right side of the guide block and the flange.

[0010] The rear end of the positioning seat has a positioning step, and the front end of the positioning seat is embedded with limit pins set at left and right intervals. The bottom surface of the rear side of the right end of the catalyst bracket is placed on the positioning step, and the front side surface of the right end of the catalyst bracket is limited by the limit pins, so as to better position the catalyst bracket.

[0011] The beneficial effect of the present invention is that the present invention adopts a method of combining end face pressing of the right end and middle part of the catalyst bracket and side face pressing of the left end side of the catalyst bracket to achieve clamping of the catalyst bracket, so there is no need to set up more clamping components to press the left end of the catalyst bracket, while simplifying the structure, it also meets the space utilization requirements of the tooling plate.
