Description

Technical Field

[0001] This utility model belongs to the field of gearbox housing production technology, and in particular relates to a gearbox housing processing table. Background Technology

[0002] For easy demolding, the four riveting holes on the side of the precision aluminum alloy die-cast gearbox housing require separate drilling. Then, recessed stepped locating hole mechanisms are milled onto the outer ends of the four riveting holes on the side of the gearbox housing. Because this milling method is simple, and the clamping and positioning speed is slow when milling the recessed stepped locating holes on the gearbox housing, it is not necessary to use a separate CNC machining center, thus reducing production costs. Therefore, a simple and low-cost gearbox housing machining table is presented. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a milling table for gearbox housing with simple structure and low operating cost.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a gearbox housing machining table, comprising a frame, a concave plate, a bracket, an automated milling machining component, a positioning fixture seat, a transverse reinforcing rod, a first longitudinal reinforcing rod, a second longitudinal reinforcing rod, and a flow collection channel. The bracket and the concave plate are both fixedly installed on the top of the frame. The automated milling machining component is set on the bracket. The transverse reinforcing rod is horizontally fixedly installed on the frame. The positioning fixture seat is fixedly installed inside the concave plate. Two first longitudinal reinforcing rods are fixedly installed on the transverse reinforcing rod. The first longitudinal reinforcing rods are fixedly supported at the bottom of the concave plate and are located directly below the positioning fixture seat. The flow collection channel is fixed on the concave plate, and the top inlet of the flow collection channel is flush with the top surface of the concave plate.

[0005] Preferably, it also includes two second longitudinal reinforcing rods, the lower ends of which are fixedly installed on the transverse reinforcing rods, and connecting rods are fixedly installed on the tops of the two second longitudinal reinforcing rods. The connecting rods are fixedly supported at the bottom of the concave plate and are located at the front side of the concave plate.

[0006] Preferably, it also includes a reinforcing block and a square positioning shell. The reinforcing block is configured as a contoured structure that matches the concave plate. The reinforcing block is welded and fixedly installed on the concave plate. The square positioning shell is fixedly installed at the top inlet of the flow collection channel. The square positioning shell has a through hole that communicates with the top inlet of the flow collection channel. The positioning fixture seat is screwed and fixed to the reinforcing block and the square positioning shell.

[0007] Preferably, the outlet end of the flow collection channel is configured as a flange structure.

[0008] Compared with the prior art, the advantages of this utility model are: the machining table has a simple structure and low operating cost, and is suitable for milling operations of stepped positioning holes with sunken outer ends of riveting holes on the side of gearbox housings. The top of the concave plate is set with an inner groove structure, which facilitates the collection of cutting fluid and milling debris to the lowest point of the concave surface of the concave plate, and then the fluid is collected and circulated through a collection channel and a hose. The first longitudinal reinforcing rod and the second longitudinal reinforcing rod solve the problem of thin concave plate and low structural strength. The first longitudinal reinforcing rod is located at the lower part of the positioning fixture seat and can provide stable support for it, thereby improving the stability of the positioning fixture seat mounting structure.

[0015] The present invention will now be described in detail with reference to specific embodiments:

[0016] like Figures 1 to 5 The gearbox housing machining table shown includes a frame 1, a concave plate 11, a bracket 2, an automated milling assembly 3, a positioning fixture seat 4, a transverse reinforcing rod 6, a first longitudinal reinforcing rod 7, a second longitudinal reinforcing rod 8, and a flow collection channel 9. The bracket 2 and the concave plate 11 are both fixedly installed on the top of the frame 1. The automated milling assembly 3 is set on the bracket 2. The transverse reinforcing rod 6 is horizontally fixedly installed on the frame 1. The positioning fixture seat 4 is fixedly installed inside the concave plate 11. Two first longitudinal reinforcing rods 7 are fixedly installed on the transverse reinforcing rod 6. The first longitudinal reinforcing rods 7 are fixedly supported at the bottom of the concave plate 11. The first longitudinal reinforcing rods 7 are located directly below the positioning fixture seat 4. The flow collection channel 9 is fixed on the concave plate 11, and the top inlet 91 of the flow collection channel 9 is flush with the top surface of the concave plate 11.

[0017] Because the concave plate 11 is relatively thin, with a thickness of only 1-2 mm to facilitate stamping, two second longitudinal reinforcing rods 8 are also included to further improve the overall structural strength of the concave plate 11. The lower ends of the second longitudinal reinforcing rods 8 are fixedly installed on the transverse reinforcing rods 6, and connecting rods are fixedly installed on the tops of the two second longitudinal reinforcing rods 8. The connecting rods are fixedly supported at the bottom of the concave plate 11 and are located at the front side of the concave plate 11. Correspondingly, the outlet of the collection channel 9 is located at the rear side of the concave plate 11. The second longitudinal reinforcing rods 8 provide support for the front side of the concave plate 11, and the connecting rods provide reinforcement for the front side of the concave plate 11, preventing the concave plate 11 from cracking and deforming during long-term use.

[0018] It also includes a reinforcing block 41 and a square positioning shell 5. The reinforcing block 41 is configured as a contour structure that matches the concave surface of the top of the concave plate 11. The reinforcing block 41 is welded and fixedly installed on the concave surface of the top of the concave plate 11. The square positioning shell 5 is fixedly installed at the top entrance of the flow channel 9. The square positioning shell 5 has a through hole that communicates with the top entrance 91 of the flow channel 9. The positioning fixture seat 4 is screwed and fixed to the reinforcing block 41 and the square positioning shell 5. Only the lower part of the positioning fixture seat 4 is fixedly installed on the concave plate 11, and its installation firmness is poor. After the side of the positioning fixture seat 4 is screwed and fixed to the reinforcing block 41 and the square positioning shell 5, the firmness of the installation structure of the positioning fixture seat 4 can be increased, the stability of the gearbox housing 10 clamped on the positioning fixture seat 4 during milling can be improved, thereby improving the accuracy of milling and improving the product quality of the gearbox housing 10.

[0019] The outlet end of the flow collection channel 9 is provided with a flange structure 92, which facilitates a sealed connection with a hose having a flange.

[0020] A cutting fluid circulation device is also installed on the machining table. During milling, the cutting fluid circulation device sprays the cutting fluid to the milling position. The gearbox housing 10, after the riveting hole is machined, is clamped and fixed on the positioning fixture 4. The automated milling assembly 3 is started to perform a stepped positioning hole milling operation on the outer end of the riveting hole of the automated milling assembly 3. The cutting fluid and milling debris are collected at the lowest point of the concave surface of the concave plate 11 (that is, at the top inlet 91 of the collection channel 9), and enter the collection channel 9 through the through hole of the square positioning shell 5. Finally, it is discharged and purified through the outlet end of the collection channel 9 with the help of a hose.
