Description

Technical Field

[0001] The utility model relates to the technical field of engine cooling nozzle processing, and specifically provides a working table for cooling nozzle processing. Background Art

[0002] The piston cooling nozzle is an important component for cooling the piston in the engine cavity and reducing the heat load of the piston.

[0003] Widely used in the field. Figure 1 and 2 As shown, the existing piston cooling nozzle generally includes a seat body 16 and a nozzle 5. The nozzle 5 is a bent tube. The nozzle 5 is fixedly connected to the seat body 16, and the nozzle 5 is connected to the oil cavity 17 in the seat body a to realize the circulation of the coolant. The production and processing of the cooling nozzle generally involves processing the seat body and the nozzle independently, then welding and fixing the nozzle on the seat body, and finally bending the outer end of the nozzle. The nozzle bending of the cooling nozzle is generally performed using a pipe bending machine. Existing pipe bending equipment usually has two modes: horizontal bending and vertical bending. The former is that the bending wheel rotates in the horizontal direction to bend the pipe, such as the bending mechanism disclosed in patents No.: CN202022081595.1, CN202120307313.7, etc.; the latter is that the bending wheel moves downward to extrude the pipe to complete the bending, such as the bending mechanism disclosed in patents No.: CN201921331215.6, CN201921350528.6, etc.

[0004] Since the nozzle of the cooling nozzle is fixed on the base and then bent, and the diameter and length of the nozzle are relatively small, it is difficult to bend the nozzle with existing horizontal bending equipment. For example, it is difficult to position the nozzle. The vertical bending equipment can effectively position the cooling nozzle by positioning the cooling nozzle on the mold on the workbench. However, this type of bending equipment is designed for cooling nozzles of one size. When the length of the cooling nozzle to be bent changes, it needs to be replaced more frequently, resulting in low production efficiency and inconvenient operation. Therefore, there is an urgent need to develop and design a workbench for cooling nozzle processing.

[0005] Therefore, a workbench for cooling nozzle processing is proposed to solve the above technical problems. Utility Model Content

[0006] The utility model aims to provide a workbench for cooling nozzle processing. By setting the top plate to be slidable, when it is necessary to adjust the socket strip, wires, and router, the top plate can be directly pushed open to expose the wire socket strip, etc., so as to solve the problems raised in the above-mentioned background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A workbench for processing cooling nozzles, comprising a support table fixed on the ground, an oil workbench arranged on the support table, an oil cylinder fixedly connected to the support table, the cylinder being located above the workbench, an output end of the cylinder fixedly connected to a fixing plate, a side wall at one end of the fixing plate being elastically connected to a shock-absorbing spring, one end of the shock-absorbing spring being elastically connected to a pressure plate, a support seat fixedly installed on the workbench, four bosses fixedly connected to the top wall of the support seat, two adjacent bosses being symmetrically arranged, two adjacent bosses forming a limiting groove, two limiting grooves being provided, a column being slidably installed in each of the limiting grooves.

[0009] Preferably, a cross bar is fixedly connected between the two columns, a locking bolt for stabilizing the cross bar is threadedly mounted on the cross bar, the bottom wall of the bolt contacts the top wall of the support seat, and a protrusion is fixedly connected to the bottom of the column.

[0010] Preferably, a scale is fixedly mounted on the top wall of the workbench, and the scale is located above the center line of the crossbar.

[0011] Preferably, two locking bolts are provided, and the two locking bolts are symmetrically arranged along the center line of the cross bar.

[0012] Preferably, a top block is fixedly connected to one side of the support seat.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. A limit groove is opened on the support seat, and the column is placed in the limit groove. The oil cavity of the nozzle is sleeved on the column for bending processing. When the length of the nozzle to be bent changes, the column can be moved to adjust according to the bending length of the nozzle. It has strong adaptability and is easy to operate.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 5 The utility model provides a workbench 3 for cooling nozzle processing, and the technical solution is as follows:

[0023] A workbench for processing cooling nozzles, comprising a support table 1 fixed on the ground, an oil workbench 3 being arranged on the support table 1, an oil cylinder 2 being fixedly connected to the support table 1, and the cylinder 2 being located above the workbench 3, characterized in that: a fixing plate is fixedly connected to the output end of the cylinder 2, a shock absorbing spring 6 is elastically connected to the side wall at one end of the fixing plate, a pressure plate 7 is elastically connected to one end of the shock absorbing spring 6, a support seat 9 is fixedly installed on the workbench 3, four bosses 14 are fixedly connected to the top wall of the support seat 9, two adjacent bosses 14 are symmetrically arranged, and two adjacent bosses 14 form a limiting groove 10. There are two limit grooves 10, and a column 8 is slidably installed in each limit groove 10. When the nozzle is bent, the equipment is powered on manually to start the cooling nozzle to be processed, and the cooling nozzle to be processed is put on the column 8. The column 8 plays a role in positioning the nozzle. The switch is pressed manually, the cylinder 2 is powered on and started, the output end of the cylinder 2 moves downward, the pressure plate 7 contacts the seat body 16, and the seat body 16 is squeezed and fixed. The pressure wheel 4 continues to move downward to contact the nozzle 5, and pressure is applied to the nozzle 5 to bend the nozzle 5. When the length of the nozzle 5 to be processed changes, the column 8 is pushed to move along the limit groove 10 to make adaptive adjustments.

[0024] A cross bar 12 is fixedly connected between the two columns 8. A locking bolt for stabilizing the cross bar 12 is threadedly installed on the cross bar 12. The bottom wall of the bolt contacts the top wall of the support seat 9. A protrusion 11 is fixedly connected to the bottom of the column 8. A groove matching the protrusion 11 is provided in the limiting groove 10. The protrusion 11 is limited so that the column 8 cannot be separated from the limiting groove 10. When the column 8 is moved, the cross bar 12 is manually pushed to move, which can ensure that the two columns 8 move at the same time, which is more convenient. A scale 15 is fixedly installed on the top wall of the workbench 3, and the scale 15 is located above the center line of the cross bar 12. When the column 8 is moved manually, the moving distance can be judged according to the position of the cross bar 12 on the scale 15, which is easy to operate. There are two locking bolts, which are symmetrically arranged along the center line of the cross bar 12. When moved to a suitable position, the two locking bolts are rotated, and the bottoms of the two fastening bolts 13 contact the workbench 3, forming a limit effect on the cross bar 12, thereby fixing the position of the cross bar 12 to prevent deviation. A top block is fixedly connected to one side of the support seat 9 to facilitate the extrusion processing of the pressure wheel 4.
