Description

TECHNICAL FIELD

[0001] The utility model relates to mechanical processing auxiliary frock technical field, especially a kind of shaping clamping fixture. BACKGROUND

[0002] In the machining process, many parts may have shape deviation after a series of machining processes, which will adversely affect the subsequent assembly and product performance. The traditional shaping method often relies on manual operation, and uses simple tools to correct the parts. This way is not only inefficient, but also the correction accuracy is difficult to guarantee. At the same time, during the manual shaping process, due to the difference in technical level and experience of the operators, it is easy to cause damage to the parts and increase the production cost. Therefore, it is of great practical significance to develop a jig that can efficiently, accurately and stably clamp and shape the parts. SUMMARY

[0003] The utility model aims at providing a jig for clamping and shaping parts, which can be widely used in various machining and manufacturing industries that require correction of part shape, to ensure that the parts meet specific shape and size requirements, and to improve product quality and production efficiency. The jig solves the above technical problems.

[0004] To achieve the above technical solutions, the technical scheme of the utility model is as follows: a shaping and clamping jig mainly consists of a base, a part placing seat, a first shaping component and a second shaping component. The base serves as the basic support structure of the entire jig, providing a stable mounting platform for other components. The part placing seat is centrally arranged on the base and is used to place the parts that need to be shaped. The first shaping component and the second shaping component are movably arranged on the base, and they can move towards the part placing seat to press the parts, thereby correcting the parts placed on the part placing seat. During detection, the first shaping component and the second shaping component move towards each other to press the parts, achieving shaping, clamping and correction of the parts.

[0005] Further, the part placing seat includes a first support element and a second support element that are adjustably mounted on the base. This adjustable mounting method allows the part placing seat to adapt to parts of different sizes and shapes. The first support element and the second support element are each provided with an inner concave U-shaped profiling placing groove. The U-shaped profiling placing groove is provided with a deformation part, which can be one of piezoelectric ceramic or elastic spring sheet. The design of the U-shaped profiling placing groove is to better fit the shape of the parts, so that the parts can be stably placed in the placing groove. The setting of the deformation part takes into account that the parts may deform slightly under certain pressure during shaping. The deformation part can adapt to such deformation and avoid the parts from being unable to be normally shaped due to the limitation of the placing groove.

[0006] Further, the first shaping component comprises a first driving source horizontally arranged on the base, and the first driving source is a first cylinder. The first cylinder is mounted on the base through a first pad plate, which can ensure the stability and firmness of the cylinder. A first sensor is arranged corresponding to the extension and retraction position of the first cylinder, which can monitor the extension and retraction state of the cylinder in real time and provide accurate data support for subsequent control and operation. A first baffle is fixedly arranged on the output end of the first cylinder, and a shaping pressure head is detachably arranged on one side of the first baffle. The shaping pressure head is a component directly contacting the parts for shaping, and its shape and material can be selected and designed according to different part requirements. The detachable mounting mode facilitates the replacement of shaping pressure heads of different shapes and sizes to adapt to the shaping requirements of various parts.

[0007] Further, the second shaping component comprises a second driving source horizontally arranged on the base, and the second driving source is a second cylinder. The second cylinder is mounted on the base through a second pad plate, and a second sensor is arranged corresponding to the extension and retraction position of the second cylinder for monitoring the extension and retraction state of the cylinder. A push plate fixing plate is arranged on the output end of the second cylinder, and a shaping core fixing seat is arranged on one side of the push plate fixing plate. A shaping rod is inserted into the shaping core fixing seat. The shaping rod is provided with a spherical surface at one end, which can better contact the surface of the part and reduce damage to the surface of the part. Pressure sensors are symmetrically embedded in the shaping core fixing seat, which can detect the pressure applied by the shaping rod to the part during the shaping process, so as to adjust the shaping operation according to the pressure condition and ensure the accuracy and safety of the shaping process.

[0008] Further, a long strip-shaped hole is symmetrically arranged through the base. The long strip-shaped hole has multiple purposes. On the one hand, it can be used for mounting and fixing other components, such as mounting the part placing seat, the first shaping component and the second shaping component on the base through bolts and other connecting members, which facilitates the installation and disassembly of the components. On the other hand, the long strip-shaped hole can also be used as an observation hole or a ventilation hole, which facilitates the observation of the state of the parts during the shaping process and ensures the air circulation in the jig.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] 1) The first shaping component and the second shaping component of the utility model can be movably arranged on the base and can mutually approach and extrude the parts on the part placing seat to correct the parts, the design of the double shaping components can apply pressure to the parts from different directions, and the parts can be effectively shaped in all dimensions. Specifically, for some irregularly shaped parts, there may be a large deviation in a certain direction, by extruding from one side through the first shaping component and extruding from the other side through the second shaping component, the shape of the parts can be more comprehensively corrected, and the accuracy and effect of shaping are improved. And in detection, the cooperative action of the first shaping component and the second shaping component can correct the parts in real time. This means that during the shaping process, the movement and pressure of the two shaping components can be adjusted in time according to the actual shape and size deviation of the parts, so that the parts can reach the required shape more quickly, and the shaping efficiency is improved.

[0011] 2) The part placing seat comprises the first supporting element and the second supporting element which are adjustably installed on the base, and the first supporting element and the second supporting element are both provided with an inner concave U-shaped profiling placing groove and a deformation part. The adjustable design makes the part placing seat adapt to parts of different sizes and shapes. Specifically, for cylindrical parts of different diameters or lengths, the positions of the first supporting element and the second supporting element can be adjusted, so that the U-shaped profiling placing groove can better fit the shape of the parts, and the stability of the parts during shaping is ensured. The U-shaped profiling placing groove is provided with a deformation part, which makes the placing groove adapt to the slight deformation of the parts during shaping, avoids the limitation of the placing groove causing the parts to be unable to be normally shaped, and further improves the success rate of shaping and the quality of the parts.

[0012] 3) The first driving source of the first shaping component selects a first cylinder, and the first cylinder is installed on the base through a first backing plate. This installation mode can provide stable support and firm connection, and ensure that the cylinder will not loosen or displace during work. Corresponding to the extension position of the first cylinder, a first sensor is arranged, which can monitor the extension state of the cylinder in real time. This makes it possible to accurately control the movement of the cylinder during shaping according to the data feedback by the sensor, and ensures that the shaping pressure head can accurately apply appropriate pressure to the parts. Specifically, if the sensor detects that the cylinder extends too fast or too slow, it may affect the shaping effect, and by adjusting the air intake amount and other parameters of the cylinder, the shaping process can be more stable and reliable. The output end of the first cylinder is fixedly provided with a first baffle, and the first baffle is detachably provided with a shaping pressure head on one side. The detachable design of the shaping pressure head facilitates the replacement of shaping pressure heads of different shapes and sizes according to the shaping requirements of different parts. This improves the universality of the jig, makes it applicable to shaping of various types of parts, and also facilitates maintenance and replacement of damaged shaping pressure heads, reducing maintenance costs.

[0013] 4) The base of this utility model is symmetrically provided with elongated through holes. These elongated holes facilitate the installation and fixation of the fixture. The part placement seat, the first shaping component, and the second shaping component can be installed on the base using bolts or other connecting parts, and the installation and disassembly process is simple and convenient. Specifically, when a component needs repair or replacement, it can be quickly removed from the base, reducing repair time and workload. The elongated holes can also serve as observation holes or ventilation holes. As observation holes, the condition of the part can be observed during the shaping process, allowing for timely detection and adjustment of problems. As ventilation holes, they ensure air circulation inside the fixture, preventing factors such as excessively high internal temperature or humidity from affecting the fixture's service life and shaping effect, thus improving the fixture's performance and reliability.
