Description

Technical Field

[0001] This application relates to the technical field of machining fixtures, and particularly to a fixture that is convenient for clamping. Background Art

[0002] The machining of shell parts is a common existing technology. Usually, the shell parts are placed on a connecting seat, and a special fixture is used to clamp and fix the shell parts, and then the shell parts are processed by corresponding processing equipment.

[0003] In the traditional machining process, usually, it is necessary for the staff to manually place the shell parts on the connecting seat for positioning, and then manually rotate the chuck on the fixture to press the shell parts onto the connecting seat, so as to complete the fixation of the shell parts.

[0004] However, in actual use, when the surface structure of the shell parts to be machined is more and the surface of the shell parts is uneven, in order to ensure the stability of the fixation of the shell parts, usually multiple fixtures need to be set on the connecting seat to clamp and fix different parts of the shell parts. When using the above-mentioned manual driving fixture to press the shell parts, it is necessary for the staff to press multiple fixtures onto the shell parts in sequence. After the machining is completed, the fixtures need to be opened in sequence through multiple operations, and the operation process is relatively cumbersome and not conducive to use. Utility Model Content

[0005] In order to solve the problem that the existing fixtures are cumbersome to use and not conducive to the overall use or disassembly of the fixtures when machining shell parts with a more complex surface structure, this application provides a fixture that is convenient for clamping.

[0008] By adopting the above technical solutions, when in use, the shell parts are placed on the connecting seat, and the shell parts are initially positioned by the positioning block. Then, the synchronous driving device can be used to drive the plurality of clamping members to clamp the shell parts simultaneously, so as to quickly fix the shell parts on the connecting seat; when it is necessary to take and replace the shell parts, the synchronous driving device can be used to drive the plurality of clamping members to open simultaneously in the reverse direction, so as to quickly disassemble the shell parts from the connecting seat. The overall operation process is simple and convenient, which is conducive to use.

One end of the air pipe is communicated with the switching valve, and the other end of the air pipe is used to communicate with an external air pump. Both the air inlet pipe and the air outlet pipe are communicated with the switching valve. The air inlet pipe is used to simultaneously supply air into the plurality of driving cylinders, and the air outlet pipe is used to discharge the gas in the plurality of driving cylinders.

[0014] By adopting the above technical solution, during use, the staff can open or close the switching valve according to actual needs, thereby controlling the connection between the switching valve and the air inlet pipe or the air outlet pipe, and further realizing synchronous clamping or opening through the plurality of driving cylinders, which is simple and convenient to use.

[0015] Preferably, the switching valve is set as a manual reversing valve.

[0016] By adopting the above technical solution, during use, by setting the switching valve as a manual reversing valve, the staff can control the telescopic movement of the piston rod of the driving cylinder by moving the lever on the manual reversing valve in different directions, thereby realizing the clamping and opening of the detection member, and the use process is more convenient.

[0017] Preferably, a limiting hole is provided on the connecting seat, and one end of the ventilation pipe passes through the limiting hole and is connected to an external air pump.

[0019] Preferably, the driving cylinder and the clamping member are respectively located on two sides of the connecting seat, and a avoidance hole is opened on the connecting seat, and the piston rod of the driving cylinder passes through the avoidance hole and is connected to the clamping member.

[0020] By adopting the above technical solution, the driving cylinder and the clamping piece are respectively arranged on both sides of the connecting seat during use, and an avoidance hole is opened on the connecting seat to facilitate the extension and retraction of the driving cylinder piston rod. In this way, while ensuring the normal operation of the clamping piece, the spatial position of the connecting seat is reasonably utilized, which is conducive to the placement of the shell connected to the connecting seat.

[0021] Preferably, a plurality of support blocks are fixed on the connecting seat, and the number of the support blocks is the same as the number of the clamping members and the arrangement positions correspond one to one.

Detailed implementation manners

[0032] The following further elaborates on the present application in conjunction with the attached Figure 1 - attached Figure 4 drawings.

[0033] The embodiment of the present application discloses a clamp that is convenient for clamping.

[0034] Referring to Figure 1 and Figure 2 , a clamp that is convenient for clamping includes a horizontally placed connecting seat 1. Both ends of the connecting seat 1 are respectively bolted to one end of an external mounting seat. An avoidance groove is formed through the connecting seat 1. A plurality of positioning blocks 2 are arranged on the connecting seat 1. The plurality of positioning blocks 2 are spaced along the circumferential side of the avoidance groove. The positioning blocks 2 are welded on the upper end surface of the connecting seat 1. In this embodiment, the positioning blocks 2 are preferably set to six.

[0035] Referring to Figure 2 and Figure 3 , a plurality of clamping members 3 are arranged on the connecting seat 1. The clamping members 3 are used to clamp the housing part on the positioning blocks 2. In this embodiment, the clamping members 3 are preferably set to four, and the four clamping members 3 are symmetrically arranged on both sides of the avoidance groove. The clamping member 3 includes a fixing block 31, a connecting rod 32, and a chuck 33. The fixing block 31 is welded on the connecting seat 1. One end of the connecting rod 32 is hinged to the fixing block 31, and the other end of the connecting rod 32 is hinged to the chuck 33. The hinge point of the connecting rod 32 and the chuck 33 is located at the center line position of the chuck 33 along the length direction.

[0036] Referring to Figure 2 , when in use, the staff places the housing part on the connecting seat 1, and the housing part is initially positioned by the positioning blocks 2. Then, by rotating the chuck 33, one end of the chuck 33 is pressed against the housing part, thereby realizing the clamping of the housing part.

[0037] Reference Figure 3 and Figure 4 On the connecting seat 1, a synchronous driving device 4 is provided. The synchronous driving device 4 is used to drive multiple chucks 33 to rotate synchronously. The synchronous driving device 4 includes a driving cylinder 5 and a gas supply assembly 6. The number of driving cylinders 5 provided is the same as the number of clamping members 3 provided, and the installation positions correspond one by one, that is, one driving cylinder 5 corresponds to driving one clamping member 3 to clamp. The driving cylinder 5 is fixed to the bottom end surface of the connecting seat 1 by bolts. An avoidance hole 8 is formed in the connecting seat 1. The top end of the piston rod of the driving cylinder 5 passes through the avoidance hole 8 and is hinged to one end of the chuck 33. At the same time, a support block 9 is also provided on the connecting seat 1. The bottom end of the support block 9 is welded and fixed to the connecting seat 1. The number of support blocks 9 provided is the same as the number of clamping members 3 provided, and the installation positions correspond one by one.

[0038] Reference Figure 4 The gas supply assembly 6 is used to supply gas to all the driving cylinders 5 simultaneously. The gas supply assembly 6 includes a transfer valve 61, a ventilation pipe 62, an air inlet pipe 63, and an air outlet pipe 64. The transfer valve 61 is fixed to the connecting seat 1 by bolts. In this embodiment, the transfer valve 61 is preferably set as a manual reversing valve. One end of the ventilation pipe 62 is communicated with the transfer valve 61, and the other end of the ventilation pipe 62 is connected to an external air pump. A main air path control valve is provided on the ventilation pipe 62. In this embodiment, the main air path control valve is preferably set as a pneumatic control valve, which is mainly used to control the connection between the ventilation pipe 62 and the external air pump.

[0039] Reference Figure 4 The air inlet pipe 63 is communicated with the transfer valve 61. A plurality of air filling ports are provided on the air inlet pipe 63. The number of air filling ports provided is the same as the number of driving cylinders 5. The plurality of air filling ports are respectively communicated with the air inlet ports of one driving cylinder 5. The air outlet pipe 64 is communicated with the transfer valve 61. A plurality of air outlet ports are provided on the air outlet pipe 64. The number of air outlet ports provided is the same as the number of driving cylinders 5. The plurality of air outlet ports are respectively communicated with the exhaust ports of one driving cylinder 5. The air inlet pipe 63 and the air outlet pipe 64 are both wound around the circumferences of all the driving cylinders 5.

[0040] Reference Figure 4, during use, the connection between the ventilation pipe 62 and the intake pipe 63 or the exhaust pipe 64 is controlled by toggling the lever on the adapter valve 61. That is, when the lever on the adapter valve 61 is toggled to the left, the ventilation pipe 62 is connected to the intake pipe 63 through the adapter valve 61, so that the outside air pump ventilates the ventilation pipe 62. After the gas passes through the adapter valve 61 and the intake pipe 63, it enters the intake ports of all the driving cylinders 5 from each inflation port, thereby controlling the pistons of all the driving cylinders 5 to extend simultaneously, so as to drive multiple chucks 33 to clamp the housing parts at the same time; when the lever on the adapter valve 61 is toggled to the right, the ventilation pipe 62 is connected to the exhaust pipe 64 through the adapter valve 61, so that the outside air pump ventilates the ventilation pipe 62. After the gas passes through the adapter valve 61 and the exhaust pipe 64, it enters the exhaust ports of all the driving cylinders 5 from each air outlet, thereby controlling the pistons of all the driving cylinders 5 to retract simultaneously, so as to drive multiple chucks 33 to open at the same time. The overall use process is simple and convenient.

[0041] Referring to Figure 4 , a limiting hole 7 is provided on the connecting seat 1. In this embodiment, the limiting hole 7 is preferably set as an oval hole. The limiting hole 7 is used to guide the placement position of the ventilation pipe 62 and at the same time limit the ventilation pipe 62. During installation, one end of the ventilation pipe 62 is connected to the adapter valve 61, and the other end passes through the limiting hole 7 and is connected to the outside air pump; during use, the inner wall of the limiting hole 7 abuts and limits the ventilation pipe 62, so as to prevent the ventilation pipe 62 from swinging and affecting the connection stability between the ventilation pipe 62 and the adapter valve 61.

[0042] The implementation principle of the embodiment of the present application is as follows: during use, the staff places the housing part on the positioning block 2 and initially positions the housing part through the positioning block 2. Then, the staff can toggle the lever on the adapter valve 61 to the left, so that the ventilation pipe 62 is connected to the intake pipe 63, thereby inflating the intake ports of multiple driving cylinders 5 at the same time, so as to control the pistons of multiple driving cylinders 5 to extend, thereby driving the chuck 33 to rotate downward until it is pressed on the housing part, and then realizing the clamping and fixing of the housing part. After that, the housing part can be machined by the processing equipment. When the housing part needs to be replaced after processing, the staff only needs to toggle the lever on the adapter valve 61 to the right, connect the ventilation pipe 62 to the exhaust pipe 64 through the adapter valve 61, thereby inflating the exhaust ports of multiple driving cylinders 5 at the same time, so as to control the pistons of multiple driving cylinders 5 to retract and reset, thereby driving the chuck 33 to rotate upward and open. Then, the housing part can be replaced. The overall operation process is simpler and more convenient than the prior art, without repeatedly manually operating the clamping member 3, and is more convenient to use.

[0043] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
