Description

Technical Field

[0001] The utility model belongs to the field of metal pipe processing, in particular to a double-side grinding device for metal pipes. Background Art

[0002] In order to meet usage requirements, long metal pipes need to be processed into short pipes of specified sizes. After the processing mechanism cuts the metal pipes, some metal parts will have burrs on their inner end faces. In actual situations, it is necessary to select the metal pipes with burrs, clamp the metal pipes using a clamping mechanism, and then grind both ends of the metal pipes using a grinding device to remove the burrs on the inner ends of the metal parts.

[0003] Most of the existing clamping mechanisms include a pair of clamping cylinders arranged opposite to each other, and the driving shaft of each clamping cylinder is connected to a clamping plate. The two clamping cylinders drive the clamping plates at the same time, and the metal pipe fittings are clamped by the two clamping plates. Although the metal pipe fittings can be clamped well in this way, the clamping is not stable enough, which affects the quality of grinding. In addition, the grinding device occupies a large area. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide a double-sided grinding device for metal pipe fittings, aiming to solve the problems that the existing double-sided grinding device for metal pipe fittings has poor grinding quality and the entire device is not compact enough.

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0017] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0018] For the convenience of explanation, only the parts related to the embodiment of the present utility model are shown.

[0019] Combination Figure 1-3As shown, the double-sided grinding device includes a machine 1, on which a pair of grinding mechanisms 2 are arranged opposite to each other, a clamping mechanism 3 is arranged between the two grinding mechanisms 2, and the clamping mechanism 3 includes a track seat 31 installed on the machine 1, on which a pair of slide seats 32 are arranged, and on which two left and right clamping plates arranged opposite to each other are arranged respectively, wherein the left clamping plate is marked 38 and the right clamping plate is marked 381, and both clamping plates are provided with a V-shaped clamping opening 33, and a screw rod 34 is inserted from the end of the track seat 32. , and the screw rod 34 passes through the two slide seats 32 in turn, a spur rack 35 is slidably provided on the machine table 1, a gear 36 is provided at the end of the screw rod 34, and the gear 36 is meshed and installed with the spur rack 35, and a clamping cylinder 37 for driving the spur rack to slide is also provided on the machine table 1, wherein the thickness of the left clamping plate 38 is greater than the thick bottom of the right clamping plate 381, and a matching fracture 39 is opened inwardly at the middle position of the right side of the left clamping plate 38 corresponding to the right clamping plate, and the left end of the right clamping plate 381 is arranged toward the fracture.

[0020] In order to meet the needs of use, long metal pipes need to be processed into short pipes of specified sizes. After the processing mechanism cuts the metal pipes, some metal parts will have burrs on their inner end faces. In actual situations, the metal pipes with burrs can be selected and the two ends of the pipes can be polished using the double-sided grinding device to remove the burrs on the inner ends of the metal parts.

[0021] When the double-sided grinding device is used to grind both ends of a metal part, the two grinding mechanisms are both in the waiting position, the two clamps are in an open state, and a metal pipe is clamped by the loading and unloading mechanism and placed between the two clamps with the metal pipe facing the two clamping ports. Then, the clamping cylinder drives the spur rack to slide, the gear rotates, and the screw rotates under the linkage of the gear, because a pair of threaded segments in opposite directions are formed on the screw. When the screw rotates, the two slides slide toward each other until the two clamps clamp the metal pipe. Then the loading and unloading mechanism releases the metal pipe, and finally, the two grinding mechanisms move toward the metal pipe and grind it. After grinding, the loading and unloading mechanism clamps the metal pipe again, the clamping mechanism releases the metal pipe, the loading and unloading mechanism takes the metal pipe away, and then clamps the next metal pipe for grinding.

[0022] The above-mentioned loading and unloading mechanism can be a transplanting mechanism or a mechanical arm. Since the above-mentioned loading and unloading mechanism is not the focus of this device, it will not be described here.

[0023] When the screw rod rotates, the two clamps move toward each other until the metal pipe is clamped. During the clamping process, the left and right clamps move toward each other, and the right clamp moves toward the fracture. When the left and right clamps clamp the metal pipe, the front end of the right clamp is located in the fracture, and the fracture guides and limits the right clamp, which can make the metal pipe clamp more stable and make the metal pipe more stable during the later grinding process.

[0024] As a preferred structure, Figure 3 The grinding mechanism 2 includes a slidable base 21, and a shaft sleeve 22 and a driving shaft 23 are rotatably provided at the upper and lower positions of the base 21. A conical grinding head 24 is provided at the front end of the shaft sleeve 22, and a driven wheel 25 is provided at the rear end. A driving wheel 26 is provided on the driving shaft 23, and a belt is sleeved between the driving wheel and the driven wheel. A driving motor 27 for driving the driving shaft to rotate is also provided on the base 21.

[0025] When the metal pipe is clamped by the clamping mechanism, the two grinding mechanisms can grind the ends of both sides of the metal pipe. Specifically, the base moves toward the end of the metal pipe on the same side, and during the movement, the grinding head rotates. When the grinding head contacts the mouth of the metal pipe, the grinding head starts to grind the inner end of the metal pipe. The base continues to move a short distance toward the metal pipe, and the grinding head moves synchronously to complete the grinding of the inner end of the metal pipe.

[0026] The shaft sleeve and the driving shaft are respectively installed at the upper and lower positions of the base, and the driving motor is also installed on the base, which can make the entire device look more compact and reduce the footprint of the entire device.

[0027] A pair of linear motors 4 are provided on the machine platform 1, and the driving ends of the linear motors 4 are connected to the base 21 on the same side. In this device, the base is slidable by the linear motors.

[0028] Further as a preferred structure, a pair of locking holes 5 are opened at the front end of the sleeve 22, and a connecting head 6 is provided on the shaft rod of the grinding head. After the connecting head 6 is inserted into the sleeve mouth of the sleeve, a locking bolt (not shown in the figure) is inserted into one of the locking holes 5, and the locking bolt passes through the connecting head and comes out from the other locking hole and is locked.

[0029] In this structure, the grinding head can be removed from the shaft sleeve, which is convenient for later replacement, cleaning and other operations. When the grinding head needs to be removed from the shaft sleeve, the locking bolt is unscrewed, and the grinding head is moved outward until the connector falls off the sleeve of the shaft sleeve. At this time, the grinding head is removed from the shaft sleeve.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the present utility model.
