Description

Technical Field

[0001] This utility model relates to the technical field of tooling for fixing shell-type parts, and in particular to a high-efficiency tooling fixture for multi-specification shell-type parts. Background Technology

[0002] The structure of a certain shell-type part 1 is as follows: Figure 1 As shown, shell-type part 1 is rectangular in shape and hollow inside. The worker requires that its shape be machined using a CNC machine tool. Before machining, the following methods must be used... Figure 2 The tooling fixture shown secures it in place. This tooling fixture includes a base plate 2, and a threaded rod 3 is welded to the top surface of the base plate 2 at both its left and right ends. The method for using this tooling fixture to fix shell-type parts is as follows:

[0003] S1. The worker supports the shell-like part 1 on the top surface of the base plate 2, such as... Figure 3 As shown, ensure that the housing part 1 is positioned between the two threaded rods 3;

[0004] S2. The worker takes two pads 4, which are the same height as the shell-type part 1, from the warehouse and places the two pads 4 on the base plate 2 respectively. Figure 4 As shown, and ensure that the two pads 4 are respectively located on the outside of the threaded rod 3;

[0005] S3. The worker places a pressure plate 5 on each of the two threaded rods 3, such as... Figure 5 As shown, and ensure that one end of the pressure plate 5 is supported on the top surface of the housing part 1, and the other end is supported on the top surface of the pad block 4;

[0006] S4. The worker threaded a locking nut 6 onto each of the two threaded rods 3, ensuring that the locking nut 6 presses against the top surface of the pressure plate 5. At this time, under the threaded connection force between the locking nut 6 and the threaded rod 3, the two pressure plates 5 fix the housing part 1 tooling between the pressure plate 5 and the base plate 2, as shown. Figure 6 As shown;

[0007] S5. Once the shell-type part 1 is fixed in place by the tooling, the worker can operate the CNC machine tool to machine the shape of the shell-type part 1.

[0008] However, although this tooling fixture can fix the shell-type part 1 in place, it still has the following technical defects:

[0009] When tooling a shell-type part 1 of a different height is required, the worker needs to retrieve two pads 4 of the same height from the warehouse before tooling the shell-type part 1 of that height can be fixed. However, there are various specifications of shell-type parts 1 in the workshop, and the height of each specification of shell-type parts 1 is different. Therefore, before each tooling, the worker needs to go to the warehouse to find pads 4 of the same height as the shell-type part 1. The worker needs to spend a lot of time in the warehouse to find the corresponding pads 4. This undoubtedly increases the tooling time of shell-type parts 1 and thus reduces the tooling efficiency of shell-type parts 1.

[0010] Therefore, there is an urgent need for a tooling fixture that can shorten the tooling fixation time of shell-type parts and greatly improve the tooling fixation efficiency of shell-type parts. Utility Model Content

[0011] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a high-efficiency tooling fixture for multi-specification shell parts that shortens the tooling fixation time and greatly improves the tooling fixation efficiency of shell parts.

[0012] The purpose of this utility model is achieved through the following technical solution: a high-efficiency tooling fixture for multi-specification shell-type parts, which includes a support plate. The support plate is provided with clamping components for clamping the shell-type parts at both its left and right ends. The clamping component on the right side includes a machine base fixed on the support plate and a fixed seat fixed on the top surface of the machine base. A protrusion extending to the left is fixed on the inner end face of the fixed seat. A rectangular groove is opened on the top surface of the protrusion. A through hole penetrating the bottom surface of the protrusion is opened at the bottom of the rectangular groove. A bearing seat fixed on the bottom surface of the protrusion is provided directly below the through hole. A threaded sleeve is rotatably installed in the bearing seat. A lead screw is threadedly connected to the threaded sleeve. The lead screw passes through the through hole upward and extends into the rectangular groove. A rectangular rod is fixedly connected to the top of the lead screw and slidably installed in the rectangular groove. The rectangular rod passes through the rectangular groove upward and a cylinder is fixed on the extended end.

[0013] The top surface of the fixed base is hinged with a first connecting rod and a second connecting rod via two pins I. A pressure block is hinged between the first connecting rod and the second connecting rod via pin II. A strip groove is formed in the first connecting rod along its length direction. The cylinder on the rectangular rod passes through the strip groove of the first connecting rod.

[0014] The two clamping components are arranged symmetrically on the left and right.

[0015] The protrusion and the fixing base are integrally formed.

[0016] The mounting base is fixed to the machine base by locking screws.

[0017] The rectangular groove and the through hole are coaxially arranged.

[0018] The threaded sleeve is fixed in the inner ring of the bearing housing.

[0019] This utility model has the following advantages: it shortens the tooling fixation time of shell-type parts and greatly improves the tooling fixation efficiency of shell-type parts. Attached Figure Description

Detailed Implementation

[0039] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description:

[0040] like Figures 7-13 As shown, a high-efficiency tooling fixture for multi-specification shell-type parts includes a support plate 7. The support plate 7 is provided with clamping components 8 at its left and right ends for clamping the shell-type parts 1. The two clamping components 8 are symmetrically arranged on the left and right sides.

[0041] The clamping assembly 8 on the right side includes a machine base 9 fixed to a support plate 7 and a fixing seat 10 fixed to the top surface of the machine base 9. The fixing seat 10 is fixed to the machine base 9 by locking screws. A protrusion 11 extending to the left is fixed to the inner end face of the fixing seat 10. The protrusion 11 and the fixing seat 10 are integrally formed. A rectangular groove 12 is formed on the top surface of the protrusion 11. A through hole 13 penetrating the bottom surface of the protrusion 11 is formed at the bottom of the rectangular groove 12. The rectangular groove 12 and the through hole 13 are coaxially arranged. A bearing seat 14 is fixedly mounted on the bottom surface of the protrusion 11 directly below the hole 13. A threaded sleeve 15 is rotatably installed inside the bearing seat 14. A lead screw 16 is threadedly connected inside the threaded sleeve 15. The lead screw 16 passes through the through hole 13 and extends into the rectangular groove 12. A rectangular rod 17 is slidably mounted in the rectangular groove 12 and fixedly connected to the top of the lead screw 16. The rectangular rod 17 passes through the rectangular groove 12 and a cylinder 18 is fixedly mounted on its extended end. The threaded sleeve 15 is fixed in the inner ring of the bearing seat 14.

[0042] The top surface of the fixed base 10 is hinged with a first connecting rod 19 and a second connecting rod 20 via two pins I. A pressure block 21 is hinged between the first connecting rod 19 and the second connecting rod 20 via a pin II. A strip groove 22 is formed in the first connecting rod 19 along its length direction. The cylinder 18 on the rectangular rod 17 passes through the strip groove 22 of the first connecting rod 19.

[0043] The working process of this utility model is as follows:

[0044] S1. The worker places a housing-type part 1 of a certain specification on the top surface of the support plate 7, ensuring that the housing-type part 1 is between the two clamping components 8, such as... Figure 14 As shown;

[0045] S2. The worker rotates the threaded sleeves 15 of the two clamping components 8. The threaded sleeves 15 rotate around the axis of the bearing seat 14. Under the threaded engagement of the threaded sleeves 15 and the lead screw 16, the lead screw 16 moves downward. The lead screw 16 drives the rectangular rod 17 to move downward, and the rectangular rod 17 drives the cylinder 18 to move downward. The cylinder 18 pulls the first connecting rod 19 downward. The first connecting rod 19 drives the pressure block 21 to move towards the top surface of the shell-like part 1. After the two threaded sleeves 15 have rotated a certain number of turns, the two pressure blocks 21 press against the top surface of the shell-like part 1, thereby fixing the tooling of this specification of shell-like part 1 between the pressure block 21 and the support plate 7. Figures 15-16 As shown;

[0046] S3. Once the shell-type part 1 is fixed in place by the tooling, the worker can operate the CNC machine tool to machine the shape of the shell-type part 1.

[0047] S4. After the shell-type part 1 is machined, the worker rotates the two threaded sleeves 15 in the opposite direction. With the threaded engagement between the threaded sleeves 15 and the lead screw 16, the lead screw 16 moves upward. The lead screw 16 drives the rectangular rod 17 to move upward. The rectangular rod 17 drives the cylinder 18 to move upward. The cylinder 18 pushes the first connecting rod 19 upward. The first connecting rod 19 drives the pressure block 21 to move away from the shell-type part 1. After the pressure block 21 separates from the shell-type part 1, the worker removes the shell-type part 1.

[0048] S5. When tooling a shell-type part of another height is required, simply repeat steps S1 to S2 to fix the tooling of the shell-type part of that specification, and then perform machining on the shell-type part 1 of that height.

[0049] Therefore, it can be seen that the first link 19, the second link 20, and the pressure block 21 of the clamping assembly 8 of this tooling fixture constitute a parallelogram linkage mechanism. When the screw sleeve 15 is rotated, the pressure block 21 can translate in the height direction, thereby enabling tooling fixation of shell-type parts 1 of different specifications in the workshop. Therefore, compared with such... Figures 2-6 The tooling fixture shown eliminates the need for workers to search for pads 4 of the same height as the shell part 1 in the warehouse, thereby greatly shortening the tooling fixation time of the shell part 1 and thus greatly improving the tooling fixation efficiency of the shell part 1.

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
