Description

Technical Field

[0001] The utility model relates to the technical field of intelligent welding systems, in particular to a fixture quick-change lathe parts processing device. Background Art

[0002] Since the structures of the positioning fixtures required for the white body products of different models are different, in order to improve production efficiency, most welding workshops currently use a four-sided turntable to switch the production method of fixtures of different models. That is, the four sides of the turntable are fixed with fixtures of four different models, and the fixtures of the corresponding models are turned to the welding robot for processing by rotating the turntable.

[0003] This method has the following technical problems in practical application: This method can only meet the welding of 4 types of models. If more models are to be processed, the fixture needs to be removed from the turntable and replaced with a fixture of the new model. However, due to the large size and heavy weight of the fixture, the disassembly and transportation process is time-consuming and labor-intensive, and the fixture switching efficiency is low. Utility Model Content

[0004] The utility model aims to provide a fixture quick-change lathe processing device to solve the problem of time-consuming and labor-intensive switching of fixtures and low efficiency in the prior art.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A fixture quick-change lathe parts processing device comprises a turntable on which four types of fixtures can be detachably installed, and also comprises a trolley. Four fixture support frames extending radially are fixed around the turntable, a row of guide wheels are rotatably arranged on both sides of the fixture support frames, a row of limit wheels are rotatably arranged on the outer sides of the guide wheels, guide plates are fixed at the bottom of both sides of the fixture, the guide plates are mounted on the guide wheels, the guide wheels are rollingly connected to the bottom surfaces of the guide plates, and the limit wheels are rollingly connected to the sides of the guide plates.

[0007] Preferably, as an improvement, the bottom surface of the end of the guide plate is provided with an upwardly inclined guide slope, and the two side surfaces of the end of the guide plate are provided with inwardly inclined guide slopes.

[0008] Preferably, as an improvement, it further comprises a positioning mechanism for positioning the fixture, the positioning mechanism comprises a positioning pin arranged on the fixture support frame, and the positioning pin is connected to a positioning cylinder.

[0009] Preferably, as an improvement, the positioning mechanism further comprises a side clamping cylinder arranged on the outside of the guide wheel, and a pad for clamping by the side clamping cylinder is fixed on the clamp.

[0010] Preferably, as an improvement, the positioning mechanism also includes an end face clamping cylinder arranged on the top of the clamp support frame, an L-shaped base plate is fixed to the end face of the clamp, an L-shaped positioning plate is fixed on the base plate, and the positioning plate is used for clamping by the end face clamping cylinder.

[0011] Preferably, as an improvement, the trolley includes a body and a traction mechanism, the traction mechanism includes a guide rail, a base is slidably arranged on the guide rail, a support column is vertically arranged on the base, a connecting plate is fixed on the top of the support seat, a connecting block for cooperating with the connecting plate is arranged at the bottom of the clamp, the support column is connected to a lifting cylinder, a rack is arranged in the guide rail, a gear is meshed on the rack, the gear is rotatably connected to the bottom of the base, the gear is connected to a drive assembly, and the drive assembly and the lifting cylinder are both installed on the base.

[0012] The beneficial effects of this program are:

[0013] 1. This solution sets a fixture support frame around the turntable, and the fixture frame is on the fixture support frame. The fixture support frame serves as a support for the fixture during processing. When replacing the fixture, the trolley docks with the fixture from the bottom through the support column, and then tows the fixture under the action of the traction mechanism. The fixture moves outward along the fixture support frame. The guide wheels and limit wheels on the fixture support frame guide and limit the fixture. The fixture can be easily and stably moved to the trolley and transported away by the trolley. The new fixture is then moved to the fixture support frame by the trolley, and then sent to the fixture support frame by the traction mechanism, thereby completing the quick change of the fixture. There is no need to manually carry the fixture, and the replacement is convenient and efficient.

[0014] 2. A guide plate is set at the bottom of the fixture to cooperate with the guide wheel and the limit wheel. The bottom surface and two side surfaces of the guide plate end are provided with guide slopes, which can guide and position the guide plate and the fixture, ensure that the fixture is smoothly inserted between the guide wheels on both sides, and ensure that the fixture is smoothly sent to the fixture support frame.

[0015] 3. Using the traction mechanism to pull the fixture can further reduce manual labor and improve the switching efficiency of the fixture. The traction mechanism uses a guide rail as a guide and a gear rack as a power source. It has a simple structure, is easy to process and has low cost.

[0016] 4. After the fixture is in place, on the one hand, the positioning cylinder drives the positioning pin to rise and insert into the fixture; on the other hand, the side clamping cylinder clamps the fixture from the side; on the other hand, the L-shaped bottom plate is buckled onto the top of the fixture support frame, and the end clamping cylinder clamps the positioning plate. This solution realizes the positioning of the fixture from these three aspects to ensure the stability of the fixture. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Example:

[0026] like Figure 1 and Figure 2 As shown, the fixture quick-change lathe processing device includes a turntable 3, a trolley 1 and a positioning mechanism for positioning the fixture 2. Four fixture support frames 4 extending radially are fixed to the turntable 3 by bolts, and the fixture 2 is installed on the fixture support frame 4 and positioned by the positioning mechanism. Figure 5 As shown, a row of guide wheels 42 are rotatably mounted on both sides of the fixture support frame 4, and a row of limit wheels 43 are rotatably mounted on the outer side of the guide wheels 42. Guide plates 41 are bolted to the bottom of both sides of the fixture 2, and the guide plates 41 are mounted on the guide wheels 42. The guide wheels 42 are in rolling connection with the bottom surface of the guide plates 41, and the limit wheels 43 are in rolling connection with the side surfaces of the guide plates 41. The bottom surface of the end of the guide plate 41 is processed with an upwardly inclined guide slope 44, and the two side surfaces of the end of the guide plate 41 are processed with inwardly inclined guide slopes 44, that is, the end of the guide plate 41 is "conical".

[0027] Combination Figure 3 and Figure 6As shown, the trolley 1 includes a body and a traction mechanism, the traction mechanism includes a guide rail 17, a base 16 is mounted on the guide rail 17, and the base 16 is slidably connected to the guide rail 17. A support column 13 is vertically installed on the base 16, a connecting plate 12 is bolted to the top of the support seat, a connecting block 11 for cooperating with the connecting plate 12 is bolted to the bottom of the clamp 2, and a lifting cylinder is connected to the support column 13, and the lifting cylinder is used to drive the support column 13 to rise and fall, and the lifting cylinder is installed on the base 16. A rack 15 is fixed in the guide rail 17 along the length direction of the guide rail 17, and the rack 15 is meshed with a gear, which is rotatably connected to the bottom of the base 16, and the gear is connected to a drive assembly, which is installed on the base 16, and the drive assembly includes a motor 14 and a reducer.

[0028] The positioning mechanism includes a positioning pin slidably mounted on the fixture support frame 4, and the positioning pin is connected to a positioning cylinder. Figure 2 As shown, the positioning mechanism also includes a side clamping cylinder 5 installed on the outside of the guide wheel 42, and a pad 51 for clamping the side clamping cylinder 5 is bolted to the clamp 2. Figure 4 As shown, the positioning mechanism also includes an end face clamping cylinder 52 installed on the top of the fixture support frame 4, and the end face of the fixture 2 is bolted with an L-shaped base plate 53, and the base plate 53 is bolted with an L-shaped positioning plate 54, which is used for clamping by the end face clamping cylinder 52.

[0029] The working principle of the fixture quick-change lathe processing device is as follows:

[0030] The trolley 1 moves to the fixture 2 that needs to be switched, the guide rail 17 extends under the fixture support frame 4, the lifting cylinder drives the support column 13 to rise, and the connecting plate 12 on the support column 13 covers the connecting block 11 on the fixture 2 from the bottom to achieve the connection between the trolley 1 and the fixture 2.

[0031] After the fixture 2 is connected to the trolley 1, the positioning cylinder drives the positioning pin to descend, and the positioning pin is separated from the fixture 2. At the same time, the side clamping cylinder 5 and the end clamping cylinder release the fixture 2, and the fixture 2 is released.

[0032] After the clamp 2 is released, the motor 14 is started to drive the gear to rotate. Due to the limitation of the guide rail 17, the gear rolls along the rack 15, thereby driving the base 16, the motor 14, the lifting cylinder and the support column 13 to move outward as a whole. The support column 13 drives the clamp 2 to move outward along the clamp support frame 4. During the movement, the guide wheel 42 and the limit wheel 43 guide and limit the clamp 2, so that the clamp 2 can be easily and stably moved to the trolley 1, and then the trolley 1 transports the clamp 2 away. The new clamp 2 is then transported to the clamp support frame 4 by the trolley 1, thereby completing the quick change of the clamp 2, without the need for manual handling of the clamp 2, and the operation is simple and efficient.

[0033] After the clamp 2 is in place, on the one hand, the positioning cylinder drives the positioning pin to rise, and the positioning pin is inserted into the clamp 2; on the other hand, the side clamping cylinder 5 clamps the clamp 2 from the side; on the other hand, the end clamping cylinder 52 clamps the clamp 2 from the end face, thereby positioning the clamp 2 from the above three aspects to ensure the stability of the clamp 2.

[0034] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
