Description

Technical Field

[0002] In the engine assembly line, there is a connecting rod breaking process, which is to break the connecting rod cap from the connecting rod body and separate it. When the connecting rod separation surface is broken, some metal powder particles on the separation surface have not fallen off, and it is often necessary to blow the separation surface clean before assembly. The conventional operation process is to open the connecting rod on the workbench and then blow it manually, which is time-consuming and labor-intensive, with low work efficiency, and it is easy for metal powder particles to fall randomly, which is not convenient for collecting and processing metal slag.

[0003] Patent publication number "CN206854267U" discloses an engine connecting rod vibration slag removal device, in which the upper vibration chassis and the lower vibration chassis are connected together by a positioning guide rail, a positioning mandrel is installed between the upper vibration chassis and the lower vibration chassis, the front of the upper vibration chassis is provided with a first torque gun, a second torque gun, a connecting rod cover first clamping cylinder and a connecting rod cover second clamping cylinder, the back of the upper vibration chassis is provided with a second high-frequency vibration pump, the front of the lower vibration chassis is provided with a connecting rod body first clamping cylinder, a connecting rod body second clamping cylinder and a V-shaped positioning block, the back of the lower vibration chassis is provided with a positioning mandrel cylinder and a first high-frequency vibration pump, the positioning mandrel cylinder is connected to the lower end of the positioning mandrel, and a dust removal device dust suction port is provided directly below the positioning mandrel. It can be seen that the diameter of the dust removal device dust suction port is larger than the outer diameter of the connecting rod big end, and the excessively large diameter reduces the negative pressure of the suction, and the suction force at the connecting rod separation surface is relatively small.

[0041] The utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0042] The utility model relates to a connecting rod slag suction device, which is used for sucking slag produced by the breaking and separation of the connecting rod 7. A double slag suction channel 13 is adopted, which corresponds to the two separation surfaces of the suction connecting rod 7, and the suction device is connected through a pipeline connecting seat 2. Compared with the existing single suction port, the diameter size is reduced. Under the same suction power, the negative pressure attraction force of the suction device at the separation surface of the connecting rod, that is, the suction force, can be made larger. The metal slag particles that have not fallen off the separation surface can be separated and fallen off under the greater suction action, so as to achieve a suction and sweeping effect.

[0043] The utility model relates to a connecting rod slag suction device, specifically, Figures 1 to 5 As shown, it includes a large positioning block, a pipe connecting seat 2 and a suction device. The large head positioning block 1 includes a fixed base 11 and a positioning column 12. The positioning column 12 is fixedly arranged on the top surface of the fixed base 11; slag suction channels 13 are arranged on opposite sides of the fixed base 11, and the slag suction channels 13 are arranged corresponding to the two connecting rod separation surfaces. The slag suction channels 13 are provided with a slag inlet and a slag outlet both connected to the wall of the fixed base 11, that is, the slag inlet and the slag outlet are both connected to the outside world; the pipe connecting seat 2 includes a mounting plate 21 and a connecting pipe 22 fixedly connected to one side of the mounting plate 21; the mounting plate 21 is adapted to be fixedly connected to the fixed base 11, and a first avoidance hole connected to the slag outlet is pierced on the mounting plate 21; the connecting pipe 22 is connected to the first avoidance hole, and the connecting pipe 22 can be integrally formed with the mounting plate 21 to enhance the sealing; the suction device is connected to the connecting pipe 22 pipeline for sucking slag; the suction device can generate negative pressure attraction, a floating vacuum cleaner. Preferably, the fixed base 11 is a truncated cone structure, and the mounting plate 21 includes an arc surface that fits the circumferential side wall of the fixed base 11. The pipe connection seat 2 of the device can connect the pipe of the suction device with the slag suction channel 13 to achieve the purpose of sucking metal slag particles.

[0044] like Figures 1 to 4 As shown, in one embodiment, the slag suction channel 13 is a slag suction groove provided on the top surface of the fixed base 11, the top of the slag suction groove is the slag inlet, and one side of the slag suction groove extends out of the edge of the fixed base 11 to form a slag outlet located on the outer side of the fixed base 11. Using the slag suction groove as the slag suction channel 13 has a simple structure and a low processing cost, and is convenient for installing the pipeline connecting base 2.

[0045] like Figure 3 As shown, in one embodiment, guide grooves 123 connected to the slag suction channel 13 are provided at positions corresponding to the slag suction channel 13 on both sides of the circumferential side surface of the positioning column 12, and when the connecting rod big end is sleeved on the positioning column 12, the connecting rod separation surface is respectively located at the guide grooves 123. The guide grooves 123 have a concentrating and guiding effect on the airflow, which can increase the suction force of the suction device at the connecting rod separation surface, and the scattered metal slag can be sucked into the suction device along the guide grooves 123. After the connecting rod cover is separated from the connecting rod body, the separation surface of the connecting rod cover is placed at the guide grooves 123 to increase the suction and sweeping effect.

[0046] In one embodiment, in order to improve the sealing between the mounting plate 21 and the fixed base 11, a sealing gasket is provided between the mounting plate 21 and the fixed base 11, and the sealing gasket is provided with a second avoidance hole corresponding to the slag outlet, so that the connecting pipe 22 can be connected to the slag suction channel 13. The sealing gasket can be designed as an annular structure, which can seal the first avoidance hole of the mounting plate 21 and the slag outlet.

[0047] In a preferred embodiment, the slag suction port of the slag suction channel 13 is an open structure, which can be a circular funnel-shaped open structure, or a Y-shaped open structure when the slag suction port expands to opposite sides. The open structure is conducive to adsorbing the granular slag scattered near the separation surface of the connecting rod, expanding the suction area, and improving the suction and sweeping effect.

[0048] like Figure 3 As shown, in one embodiment, the positioning column 12 is fixedly arranged on the top surface of the fixed base 11 to form a stepped platform-like structure with a small upper end and a large lower end; the positioning column 12 is a stepped platform column structure that radially expands from top to bottom, and the multiple steps of the positioning column 12 are designed to correspond to connecting rods 7 of different sizes and specifications, so that it can be inserted into the connecting rod large end holes of connecting rods 7 of different specifications for positioning and fixing, thereby improving the versatility of the device.

[0049] In certain embodiments, such as Figures 3-4 As shown, the fixed base 11 includes a base movable end 111 and a base fixed end 112 coupled and abutted against the base movable end 111; the positioning column 12 includes a movable column 121 fixedly mounted on the base movable end 111 and a fixed column 122 fixedly mounted on the base fixed end 112; when the base movable end 111 abuts against the base fixed end 112, the movable column 121 couples and abuts against the fixed column 122 to form a cylindrical structure. The fixed column 122 fixedly connected to the base fixed end 112 is inserted into the connecting rod big end hole abutting against one side of the connecting rod body to limit the connecting rod body, and the movable column 121 fixedly connected to the base movable end 111 is inserted into the connecting rod big end hole abutting against one side of the connecting rod cover, and when the base movable end 111 moves away from the base fixed end 112, the movable column 121 can push the connecting rod cover to move, so that it is separated from the connecting rod body.

[0050] like Figures 3-4As shown, in one embodiment, the movable end 111 of the base includes a fan-shaped columnar structure, and the central angle of the fan-shaped circle of the movable end 111 of the base is 90 to 150°, which can be any value between 90° and 150°, preferably around 120°, so as not to affect the installation of the mounting plate 21 on the fixed base 11, and the mounting plate 21 is fixedly connected to the fixed end 112 of the base corresponding to the slag suction channel 13. Preferably, the positioning column 12 is coaxially arranged with the fixed base 11, and the separation surface between the movable column 121 and the fixed column 122 coincides with the separation surface between the fixed end 112 of the base and the movable end 111 of the base, which can ensure that the effective contact surface of the movable column 121 on the connecting rod cover is sufficient, and at the same time make the structure simpler, and facilitate the manufacture of the big head positioning block 1.

[0051] In one embodiment, Figure 1 , Figure 2 and Figure 5 As shown, the connecting rod slag suction device also includes a separation mechanism 5 and a small head positioning block 6. The separation mechanism 5 is used to drive the movable end 111 of the base to move in a direction away from the fixed end 112 of the base, so as to enable the movable column 121 to push the connecting rod cover to separate from the connecting rod body. The separation mechanism 5 includes but is not limited to a telescopic device that is transmission-connected to the movable end 111 of the base; the small head positioning block 6 is fixedly arranged relative to the large head positioning block 1, and the small head positioning block 6 is provided with a limiting column 61, which is used to be inserted into the small head hole of the connecting rod and abut against the hole wall close to or away from the positioning column 12. Based on the limiting effect of the positioning column 12 inserted into the large head hole of the connecting rod, when the small head hole of the connecting rod is limited on one side close to or away from the positioning column 12, the connecting rod 7 can be limited by two limiting points.

[0052] Since the multiple steps of the positioning column 12 are coaxially arranged, the axes of the connecting rod small head holes do not overlap when connecting rods 7 of different specifications are installed. In actual use, the limiting column 61 can be set as a non-coaxial stepped column type structure, so that the multiple steps of the limiting column 61 are adapted to be plugged and fixed to connecting rod small heads of different specifications, such as Figures 1-2 shown.

[0053] like Figure 4 As shown, in one embodiment, the end of the connecting pipe 22 away from the mounting plate 21 is connected to an L-shaped steering pipe joint 3, an extension pipe 4 and a suction device in a pipeline sealing manner in sequence; specifically, the extension pipe 4 extends to the edge of the workbench, and then a steering pipe joint 3 is connected so that the channel outlet faces downward, and the pipe seal of the suction device is clamped on the steering pipe joint 3 with the channel outlet facing downward using a clamp. Each connection of the connecting pipe 22, the steering pipe joint 3, the extension pipe 4 and the pipe of the suction device can be bolted using a threaded structure, and the steering pipe joint 3 can use a standard stainless steel pipe joint. When the steering channel outlet faces downward, the suction device and its pipe can be placed under the workbench surface to avoid affecting the operation on the surface, and at the same time, it is more beautiful.

[0054] In one embodiment, a suction pipe is provided at the power suction end of the suction device, and a plurality of branch joints are provided on the suction pipe. The branch joints correspond to the sealing connection connecting pipe 22. One suction device can be used to be responsible for the suction work of the connecting rod separation surfaces at multiple large head positioning blocks 1, thereby improving the utilization rate of the suction device, saving the number of suction devices, and saving costs.

[0055] In one embodiment, a method of fixing the mounting plate 21 to the fixed base 11 is described. The mounting plate 21 is provided with a plurality of mounting holes, and the fixed base 11 is provided with a plurality of threaded holes. The threaded holes are threadedly connected with bolts passing through the corresponding mounting holes. The mounting plate 21 is bolted to the threaded holes of the fixed base 11 by means of a plurality of bolts passing through the plurality of mounting holes. The installation is convenient and the fixation is reliable.

[0056] During actual use, the large end hole of the connecting rod 7 is sleeved on the step adapted by the positioning column 12, and the small end hole of the connecting rod is sleeved on the step adapted by the limiting column 61. At this time, the connecting rod separation surface is located above the slag suction channel 13, and the vacuum device is started. When using the separation device, the movable column 121 is driven to move in the direction away from the fixed column 122 (i.e., away from the connecting rod body), so that the movable column 121 pushes the connecting rod cover to separate from the connecting rod body, and the connecting rod cover separation surface is moved to the guide groove 123. Under the negative pressure suction of the suction device, the scattered and unseparated metal slag on the connecting rod separation surface are sucked into the slag suction channel 13, and are collected and processed centrally, so that the connecting rod body and the connecting rod cover meet the assembly requirements.

[0057] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. The utility model may have various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected.
