Description

Technical Field

[0001] The utility model relates to the technical field of gear pumps, in particular to a turning and fixing tool for a front cover of a gear pump. Background Art

[0002] The gear pump is composed of two gears, a pump body and front and rear covers. In terms of the processing of the gear pump cover, due to its irregular shape, it is difficult to fix it on the operating table of the machining center, which also directly affects the processing accuracy of the shaft hole and other structures on its inner wall. The patent announcement number CN211135545U records a gear pump front cover turning and fixing tool. When in use, the second fixed disk is fixedly connected to the lathe through the fixing bolt B, and the front end cover to be processed is inserted into the installation groove between the first fixed disk and the second fixed disk. Then, by rotating the locking bolt C, the clamping plate moves toward the first fixed disk side, driving the clamping block to press the front end cover to be processed into the installation groove, and the surface to be processed protrudes from the first fixed disk. The front cover to be processed is placed in the installation groove, and the protrusion is used to limit it with the placement position. However, this turning and fixing tool only uses the protrusion to fix and limit the front cover to be processed, which is easy to loosen, thereby causing the front cover to be processed to be offset, so that the practicality of the turning and fixing tool for the front cover to be processed is low.

[0003] Based on this, a gear pump front cover turning and fixing tool is now provided, which can eliminate the disadvantages of the existing device. Utility Model Content

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] Example 1

[0028] In one embodiment, Figure 1-Figure 7 As shown, a gear pump front cover turning and fixing tooling includes a base 11 and a workbench 16, wherein the base 11 and the workbench 16 are fixedly connected by four legs 15, a loading frame 12 is fixedly installed on the right side of the upper end of the base 11, and an operating frame 36 is fixedly installed on the left side of the upper end of the workbench 16; a transfer structure is arranged inside the loading frame 12 and in the middle of the upper end of the workbench 16, for transferring the gear pump front cover located inside the loading frame 12; a fixing structure is arranged on the left side of the upper end of the workbench 16, for fixing the gear pump front cover.

[0029] In this embodiment, the staff transfers the gear pump front cover located inside the loading frame 12 through the transfer structure, and the gear pump front cover transferred to the designated position is fixed by the fixing structure, thereby facilitating the subsequent turning operation on the gear pump front cover.

[0030] In one embodiment, Figure 1 , Figure 2 and Figure 4 As shown, the transfer structure includes a first electric push rod 13, which is fixedly installed in the middle position inside the loading frame 12, and the output end of the first electric push rod 13 is fixedly connected to the first push plate 14. The upper end of the first push plate 14 is used to place the front cover of the gear pump. The loading frame 12 is located on the right side of the workbench 16, and a transportation component is installed in the middle position of the upper end of the workbench 16.

[0031] The gear pump front cover is pushed upward by the first electric push rod 13, and the gear pump front cover is then transported by the transport assembly, thereby realizing automatic loading of the gear pump front cover and reducing the workload of the staff.

[0032] In one embodiment, Figure 2 , Figure 3 and Figure 5As shown, the transport assembly includes a second electric push rod 17, which is fixedly installed in the middle position of the upper end of the workbench 16, the telescopic end of the second electric push rod 17 is fixedly connected to the rotating motor 18, the output end of the rotating motor 18 is fixedly connected to the rotating plate 19, the lower end of the rotating plate 19 is symmetrically fixed with fixed columns 20, the lower end of the fixed column 20 is fixedly connected to the fixed plate 21, the lower end of the fixed plate 21 is symmetrically provided with suction cups 24, the upper end of the rotating plate 19 is symmetrically fixed with charging and discharging air pumps 22, and the charging and discharging air pumps 22 are connected to the suction cups 24 through air pipes 23.

[0033] The second electric push rod 17 moves downward until the suction cup 24 contacts the gear pump front cover, and then the air between the suction cup 24 and the gear pump front cover is sucked out by the charging and discharging air pump 22 on the right, so that the gear pump front cover and the suction cup 24 are fixed, and then the second electric push rod 17 moves upward, and then the rotating plate 19 is rotated by the rotating motor 18 until the gear pump front cover is located directly above the operating frame 36, and the charging and discharging air pump 22 on the right is turned to the left position, and then the second electric push rod 17 moves downward until the bottom of the gear pump front cover contacts the auxiliary component under the operating frame 36, and then the charging and discharging air pump 22 is controlled to inflate between the suction cup 24 and the gear pump front cover, so that the gear pump front cover is separated from the suction cup 24, and the above operations are repeated to realize the loading and transportation of the gear pump front cover, thereby reducing the workload of the staff.

[0034] In one embodiment, Figure 1 and Figure 6 As shown, the fixed structure includes a first moving frame 25 and a second moving frame 26, the first moving frame 25 and the second moving frame 26 are installed on the left side of the upper end of the workbench 16, the first moving frame 25 and the second moving frame 26 are symmetrically arranged on the left and right sides of the operating frame 36, the second moving frame 26 is fixedly connected with a limit rod 29 inside, and the outer wall of the limit rod 29 is slidably connected to two second moving blocks 31, a driving motor 27 is installed at the front end of the first moving frame 25, the output end of the driving motor 27 is fixedly connected to a bidirectional screw 28, both ends of the bidirectional screw 28 are threadedly connected to the first moving block 30, the upper ends of the first moving block 30 and the second moving block 31 are fixedly connected to a clamping plate 32, and an auxiliary component is installed below the operating frame 36.

[0035] Since the threads of the two ends of the bidirectional screw 28 are in opposite directions, the first moving blocks 30 at the two ends of the bidirectional screw 28 are synchronously moved in opposite or opposite directions. When the front cover of the gear pump contacts the auxiliary component, the bidirectional screw 28 is driven to rotate by the driving motor 27, and the first moving blocks 30 at the two ends of the bidirectional screw 28 and the second moving blocks 31 at the two ends of the limit rod 29 move synchronously relative to each other, so that the clamping plate 32 fixes the front cover of the gear pump, which is conducive to the subsequent turning operation of the front cover of the gear pump.

[0036] In one embodiment, Figure 2 and Figure 7 As shown, the auxiliary component includes a third electric push rod 33 , which is fixedly mounted on the left side of the upper end of the base 11 , and the telescopic end of the third electric push rod 33 is fixedly connected to the third push plate 34 .

[0037] The third push plate 34 is pushed upward by the third electric push rod 33, so that the front cover of the gear pump is higher than the operating frame 36, and then the clamping plate 32 can clamp and fix the front cover of the gear pump, avoiding problems in the fixing process.

[0038] Example 2

[0039] In one embodiment, Figure 6 As shown, the clamping surface of the clamping plate 32 is provided with a silicone pad.

[0040] The silicone cushion has good flexibility and compressibility, and plays a role of buffering protection when the clamping plate 32 fixes the front cover of the gear pump, thereby preventing the front cover of the gear pump from being deformed when being fixed.

[0041] In one embodiment, Figure 6 As shown, the surface of the silicone pad is provided with anti-slip patterns.

[0042] The anti-slip pattern on the surface of the silicone pad can increase the friction coefficient of the silicone pad surface, thereby increasing the friction between the silicone pad and the gear pump front cover, and preventing the gear pump front cover from being loosely fixed.

[0043] In one embodiment, Figure 7 As shown, the upper end of the third push plate 34 is fixedly connected to the limiting column 35 .

[0044] By arranging a limiting column 35 at the upper end of the third push plate 34, the front cover of the gear pump is limited to prevent the front cover of the gear pump from shifting during the fixing process, thereby affecting the subsequent turning work.

[0045] The above embodiment discloses a gear pump front cover turning and fixing tooling, wherein the gear pump front cover is pushed upward by the first electric push rod 13, and the second electric push rod 17 moves downward until the suction cup 24 contacts the gear pump front cover, and then the air between the suction cup 24 and the gear pump front cover is sucked out by the right-side charging and discharging air pump 22, so that the gear pump front cover and the suction cup 24 are fixed, and then the second electric push rod 17 moves upward, and then the rotating plate 19 is rotated by the rotating motor 18 until the gear pump front cover is located directly above the operating frame 36, the right-side charging and discharging air pump 22 is turned to the left position, and then the second electric push rod 17 moves downward until the bottom of the gear pump front cover is in contact with the operating frame The auxiliary component below 36 contacts, and then the inflation and deflation air pump 22 is controlled to inflate air between the suction cup 24 and the gear pump front cover, so that the gear pump front cover is separated from the suction cup 24. The above operations can be repeated to realize the loading and transportation of the gear pump front cover, and the third push plate 34 is pushed upward by the third electric push rod 33, so that the gear pump front cover is higher than the operating frame 36, and the bidirectional screw 28 is driven to rotate by the driving motor 27. The first moving blocks 30 at both ends of the bidirectional screw 28 and the second moving blocks 31 at both ends of the limit rod 29 move synchronously relative to each other, so that the clamping plate 32 fixes the gear pump front cover, which is beneficial to the subsequent turning operation of the gear pump front cover.

[0046] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
