Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a clamping and flipping mechanism. Background Technology

[0002] Machining is a process that alters the shape, size, or properties of a workpiece using mechanical equipment. Currently, when machining crankcase inserts, one end of the insert must first be planar-cut, and then the insert must be flipped over to chamfer the other end. This requires the use of a clamping and flipping mechanism.

[0003] However, most existing clamping and flipping mechanisms have simple structures, making it difficult to clean the chips on the clamping rods. When clamping the box insert, the chips on the clamping rods can easily cause uneven contact between the clamping rods and the outer surface of the box insert, resulting in displacement of the box insert after clamping. Furthermore, it can easily cause extrusion damage to the outer surface of the box insert, reducing the practicality of the device. Therefore, to address the above technical problems, a clamping and flipping mechanism is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes a clamping and flipping mechanism, which facilitates the cleaning of chips on the clamping rod, prevents displacement of the box insert after clamping and damage to the outer surface of the box insert, and improves the practicality of the device.

[0005] A clamping and flipping mechanism, comprising:

[0006] The motor can be fixed on the machine tool slide, and the output end of the motor is coaxially connected to a mounting plate;

[0007] A clamping assembly includes clamping rods and a drive assembly. Two sets of clamping rods, capable of sliding radially along one end of the mounting plate, are disposed opposite each other. The drive assembly is mounted on the mounting plate and connected to the two sets of clamping rods, used to drive the two sets of clamping rods to move towards or away from the axis of the mounting plate.

[0008] The air blowing assembly includes a piston cylinder and a piston rod respectively disposed on two sets of clamping rods; a piston head is disposed on the piston rod, and the piston head is slidably disposed inside the piston cylinder; an inlet one-way valve and an outlet one-way valve are disposed around the piston cylinder; an outlet nozzle is detachably disposed on both sets of clamping rods, and the outlet of the two sets of outlet nozzles faces the opposite face of the two sets of clamping rods respectively; the outlet one-way valve is connected to a three-way connector, and the three-way connector is connected to the two sets of outlet nozzles through an air guide hose.

[0009] The beneficial effects of the above-mentioned clamping and flipping mechanism are as follows:

[0010] When the drive assembly moves the two sets of clamping rods to clamp the housing insert, the piston head slides inside the piston cylinder, allowing air inside the piston cylinder to be blown out through the exhaust check valve, three-way connector, and air guide hose from the two sets of exhaust nozzles to clean the chips on the opposite surfaces of the two sets of clamping rods. This facilitates cleaning the chips on the two sets of clamping rods, prevents displacement of the housing insert after clamping, and avoids damage to the outer surface of the housing insert, thus improving the practicality of the device.

[0011] In one embodiment, the two sets of clamping rods have corresponding arc grooves on their opposite faces, and the air outlets of the two sets of air nozzles face the two sets of arc grooves respectively. By creating the arc grooves, the contact area between the clamping rods and the outer surface of the housing insert can be increased, thereby improving the stability of clamping the housing insert.

[0012] In one embodiment, each of the two sets of clamping rods has an open sleeve on its opposite side, and the two sets of air nozzles are respectively clamped in the two sets of open sleeves. The air nozzles and clamping rods are connected by a snap-fit ​​connection, which makes it convenient to install and remove the air nozzles and facilitates replacement if the air nozzles are damaged.

[0013] In one embodiment, a filter screen cover is fitted onto the intake check valve. By providing the filter screen cover, external debris can be prevented from clogging the intake check valve or entering the piston cylinder and affecting the exhaust gas.

[0014] In one embodiment, a T-shaped groove is provided at one end of the mounting plate, and a T-shaped slider is provided at one end of each of the two sets of clamping rods. The two sets of T-shaped sliders are slidably disposed in the T-shaped groove along the radial direction of the mounting plate. The cooperation of the T-shaped groove and the T-shaped slider can improve the stability of the sliding of the two sets of clamping rods.

[0015] In one embodiment, the driving assembly includes an electric telescopic rod and connecting rods. A mounting groove is provided on one side of the T-shaped slide, and the electric telescopic rod is disposed within the mounting groove and coaxial with the mounting plate. Two sets of connecting rods are hinged to the telescopic ends of the electric telescopic rod, and the other ends of the two sets of connecting rods are respectively hinged to two sets of T-shaped sliders. By controlling the retraction of the electric telescopic rod, the two sets of connecting rods can drive the two sets of T-shaped sliders to move together, thereby causing the two sets of clamping rods to move together. Conversely, by controlling the extension of the electric telescopic rod, the two sets of connecting rods can drive the two sets of T-shaped sliders to move away, thereby causing the two sets of clamping rods to move away. This facilitates the closing or moving of the two sets of clamping rods.

[0016] In one embodiment, a mounting plate is provided at the bottom of the motor. The mounting plate has oblong holes along its thickness direction for bolts to pass through. Multiple sets of oblong holes are arranged in an array along the length and width directions of the mounting plate. By connecting the mounting plate to the machine tool slide through the oblong holes with bolts, the mounting plate can be fixed to the machine tool slide, thereby fixing the device to the machine tool slide. The connection between the device and the machine tool slide is convenient, and the bolts can move within the oblong holes, which facilitates horizontal adjustment of the position of the mounting plate fixed to the machine tool slide. This, in turn, facilitates adjustment of the relative position of the device and the machine tool slide, allowing for adjustments as needed and improving the applicability of the device.

[0025] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0026] Please see Figures 1 to 3One embodiment of the clamping and flipping mechanism includes a motor 10, a clamping assembly, and an air blowing assembly.

[0027] The motor 10 can be fixed on the machine tool slide, and the output end of the motor 10 is coaxially connected to the mounting plate 101. Specifically, the bottom end of the motor 10 is provided with a mounting plate 104, and the mounting plate 104 has oblong holes 105 for bolts to pass through along the thickness direction. Multiple sets of oblong holes 105 are arranged in an array along the length and width directions of the mounting plate 104.

[0028] In the above embodiments, the mounting plate 104 can be fixed on the machine tool slide plate by connecting the bolt through the oblong hole 105 and the machine tool slide plate (not shown). This fixes the device on the machine tool slide plate. The connection between the device and the machine tool slide plate is convenient, and the bolt can move within the oblong hole 105, which facilitates the horizontal adjustment of the position of the mounting plate 104 fixed on the machine tool slide plate. This, in turn, facilitates the adjustment of the relative position between the device and the machine tool slide plate, making it easy to adjust according to needs and improving the applicability of the device.

[0029] Please see Figure 1 and Figure 2 In one embodiment, the clamping assembly includes clamping rods 20 and a driving assembly. Two sets of clamping rods 20 that can slide radially along one end of the mounting plate 101 are disposed opposite each other. The driving assembly is disposed on the mounting plate 101 and connected to the two sets of clamping rods 20, and is used to drive the two sets of clamping rods 20 to move towards or away from the axis of the mounting plate 101.

[0030] Specifically, in the above embodiment, a T-shaped groove 102 is provided at one end of the mounting plate 101, and a T-shaped slider 203 is provided at one end of each of the two sets of clamping rods 20. The two sets of T-shaped sliders 203 are slidably disposed in the T-shaped groove 102 along the radial direction of the mounting plate 101. The driving assembly includes an electric telescopic rod 204 and a connecting rod 205; a mounting groove 103 is provided on one side of the T-shaped groove 102, and the electric telescopic rod 204 is disposed in the mounting groove 103 and coaxial with the mounting plate 101. Two sets of connecting rods 205 are hinged to the telescopic ends of the electric telescopic rod 204, and the other ends of the two sets of connecting rods 205 are respectively hinged to the two sets of T-shaped sliders 203.

[0031] In the above embodiment, the stability of the sliding of the two sets of clamping rods 20 can be improved by setting the T-shaped groove 102 and the T-shaped slider 203 in cooperation. By controlling the electric telescopic rod 204 to retract, the two sets of T-shaped sliders 203 can be moved together through the two sets of connecting rods 205, thereby causing the two sets of clamping rods 20 to move together. Conversely, by controlling the electric telescopic rod 204 to extend, the two sets of T-shaped sliders 203 can be moved away through the two sets of connecting rods 205, thereby causing the two sets of clamping rods 20 to move away. It is convenient to drive the two sets of clamping rods 20 to move together or away.

[0032] Please see Figures 1 to 3 In one embodiment, the air blowing assembly includes a piston cylinder 30 and a piston rod 301 respectively disposed on two sets of clamping rods 20; a piston head 302 is disposed on the piston rod 301, and the piston head 302 is slidably disposed inside the piston cylinder 30; an inlet one-way valve 303 and an outlet one-way valve 304 are disposed around the piston cylinder 30; an outlet nozzle 305 is detachably disposed on both sets of clamping rods 20, and the outlets of the two sets of outlet nozzles 305 face the opposite faces of the two sets of clamping rods 20 respectively; the outlet one-way valve 304 is connected to a three-way connector 306, and the three-way connector 306 is connected to the two sets of outlet nozzles 305 through an air guide hose 307.

[0033] In the above embodiment, when the two sets of clamping rods 20 move together, the piston head 302 slides inside the piston cylinder 30, allowing air inside the piston cylinder 30 to be blown out from the two sets of air nozzles 305 through the air outlet one-way valve 304, the three-way connector 306, and the air guide hose 307 to clean the chips on the opposite surfaces of the two sets of clamping rods 20. This facilitates cleaning the chips on the clamping rods 20, avoids displacement of the housing insert (not shown) after clamping, and prevents damage to the outer surface of the housing insert, thus improving the practicality of the device. When the two sets of clamping rods 20 move away from each other, the piston head 302 slides in the opposite direction inside the piston cylinder 30. At this time, outside air can enter the piston cylinder 30 through the air inlet one-way valve 303, which facilitates blowing air to clean the chips on the opposite surfaces of the two sets of clamping rods 20 when the two sets of clamping rods 20 move together again.

[0034] Based on the above embodiment, furthermore, the two sets of clamping rods 20 are provided with corresponding arc grooves 201 on their opposite faces, and the air outlets of the two sets of air nozzles 305 are respectively oriented towards the two sets of arc grooves 201. By providing arc grooves 201, the contact area between the clamping rods 20 and the outer surface of the housing insert can be increased, thereby improving the stability of clamping the housing insert.

[0035] Based on the above embodiment, furthermore, each of the two sets of clamping rods 20 is provided with an open sleeve 202 on the opposite side, and the two sets of air outlet nozzles 305 are respectively clamped in the two sets of open sleeves 202. The air outlet nozzles 305 and the clamping rods 20 are connected by a snap-fit ​​connection, which makes it convenient to install and remove the air outlet nozzles 305 and facilitates replacement after the air outlet nozzles 305 are damaged.

[0036] Based on the above embodiments, a filter screen cover 308 is further provided on the intake check valve 303. By providing the filter screen cover 308, external debris can be prevented from clogging the intake check valve 303 or entering the piston cylinder 30 and affecting the exhaust gas.

[0037] The specific implementation of the above-mentioned clamping and flipping mechanism is as follows:

[0038] After the plane cutting of the housing insert is completed, the machine tool slide moves the motor 10 to position the housing insert between the two sets of clamping rods 20. At this time, by controlling the retraction of the electric telescopic rod 204, the two sets of connecting rods 205 can drive the two sets of T-shaped sliders 203 to move together, thereby causing the two sets of clamping rods 20 to move together. The movement of the two sets of clamping rods 20 together allows the piston head 302 to slide inside the piston cylinder 30, blowing the air inside the piston cylinder 30 out through the one-way valve 304, the three-way connector 306, and the air guide hose 307 from the two sets of air nozzles 305 to clean the chips on the opposite surfaces of the two sets of clamping rods 20. Cleaning the chips on the clamping rods 20 is convenient, avoiding displacement and damage to the outer surface of the housing insert after clamping, and improving the practicality of the device. After the two sets of clamping rods 20 move together to clamp the housing insert, the machine tool fixture... (Not shown in the figure) The clamping of the housing insert is released. At this time, the installation plate 101 is rotated 180° by the motor 10 to flip the housing insert. After the housing insert is flipped, the machine tool fixture fixes the housing insert again. Then, the electric telescopic rod 204 is extended, which drives the two sets of T-shaped sliders 203 to move away through the two sets of connecting rods 205. This causes the two sets of clamping rods 20 to move away, and the clamping of the housing insert is released when the two sets of clamping rods 20 move away. The piston head 302 slides in the opposite direction in the piston cylinder 30. At this time, the outside air can enter the piston cylinder 30 through the air inlet one-way valve 303, which makes it easier to blow air to clean the opposite surfaces of the two sets of clamping rods 20 when the two sets of clamping rods 20 close and move again. Finally, the machine tool slide moves the motor 10 in the opposite direction to reset and perform chamfering cutting on the housing insert.
