Description

Technical Field

[0001] This utility model relates to the field of parts processing technology, and in particular to a processing fixture for automatic clamping and positioning of parts. Background Technology

[0002] Parts processing fixtures are auxiliary devices specifically designed or selected to meet the precision requirements of parts processing, improve production efficiency, and ensure operational safety. By positioning and clamping the workpiece, they enable the corresponding processing equipment to stably process the workpiece. Their performance directly affects the stability of processing quality and the smoothness of the production process, and is an indispensable technical guarantee for achieving large-scale and specialized production.

[0003] After automatically positioning and clamping a cylindrical workpiece using an electrically controlled slide and fixture, the workpiece needs to be milled. However, the metal chips generated during milling enter the electrically controlled slide through its adjustment slot. This makes it impossible for operators to quickly clean the metal chips inside the slide during subsequent maintenance; the baffle must be removed to perform the cleaning operation, thus extending the maintenance time. Utility Model Content

[0004] The purpose of this invention is to solve the problem that iron filings generated during milling enter the interior of the electrically controlled slide through the adjustment groove. This makes it difficult for operators to quickly clean the iron filings inside the electrically controlled slide during subsequent maintenance. Therefore, this invention proposes a machining fixture for automatic clamping and positioning of parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a machining fixture for automatic clamping and positioning of parts, including an electrically controlled slide table, a workpiece positioning fixture fixedly connected to the drive end of the electrically controlled slide table, a workpiece baffle fixedly connected to one end of the electrically controlled slide table, and sliding groove sealing assemblies provided on both sides of the electrically controlled slide table. The sliding groove sealing assembly includes two sets of electrically controlled cylinders, a transmission frame, and a sealing strip. The drive ends of the two sets of electrically controlled cylinders are fixedly connected to one end of the transmission frame, and the sealing strip is provided at the other end of the transmission frame.

[0006] Preferably, the other end of the transmission frame has several mounting grooves arranged in a linear manner, and one side of the sealing strip is fixedly connected with several threaded rods arranged in a linear manner. One end of each threaded rod movably passes through the interior of the mounting groove and is threadedly connected to a nut.

[0007] Preferably, the end of the sealing strip is movably fitted with a rubber sleeve.

[0008] Preferably, the workpiece positioning fixture includes a first positioning side plate and a first positioning protrusion, wherein the first positioning protrusion is fixedly installed on one side of the first positioning side plate.

[0009] Preferably, a second positioning protrusion is fixedly connected to one side of the workpiece baffle.

[0010] Preferably, a positioning frame is provided on the outer side of the electronically controlled cylinder, the inner side of the positioning frame is attached to the outer side of the electronically controlled cylinder, and the two ends of the positioning frame are fixedly installed at the edge of the bottom of the electronically controlled slide table by bolts.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the transmission frame and sealing strip are driven by an electric cylinder to move toward the electric slide table, so that the sealing strip enters the groove of the electric slide table. When the milling machine processes the round tube workpiece, the generated iron filings will not enter the interior of the electric slide table through the groove, thus improving the sealing performance of the electric slide table. When the electric slide table needs to be driven for adjustment, the electric cylinder will drive the sealing strip to slide out of the groove without interfering with the movement trajectory of the electric slide table.

[0012] 2. In this utility model, by replacing the sealing strip, the machining fixture for automatic clamping and positioning of the part can clamp round tube workpieces of different lengths, thereby expanding the range of workpiece types that the fixture can clamp, reducing the enterprise's investment in purchasing and maintaining various special fixtures, and significantly improving the overall utilization efficiency of the equipment.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a machining fixture for automatic clamping and positioning of parts, including an electrically controlled slide table 1. A workpiece positioning fixture 11 is fixedly connected to the drive end of the electrically controlled slide table 1. A workpiece baffle 2 is fixedly connected to one end of the electrically controlled slide table 1. Slide groove sealing assemblies 3 are provided on both sides of the electrically controlled slide table 1. The slide groove sealing assembly 3 includes two sets of electrically controlled cylinders 31, a transmission frame 32, and a sealing strip 33. The drive ends of the two sets of electrically controlled cylinders 31 are fixedly connected to one end of the transmission frame 32, and the sealing strip 33 is provided at the other end of the transmission frame 32. The workpiece positioning fixture 11 includes a first positioning side plate 111 and a first positioning protrusion 112. The first positioning protrusion 112 is fixedly installed on one side of the first positioning side plate 111, and a second positioning protrusion 21 is fixedly connected to one side of the workpiece baffle 2.

[0018] The specific settings and functions of this embodiment are described below. One end of the cylindrical workpiece to be processed is clamped to the outside of the first positioning protrusion 112. Then, the electric control slide 1 is started. The drive end of the electric control slide 1 drives the workpiece positioning fixture 11 and the cylindrical workpiece to move towards the workpiece baffle 2, so that the other end of the cylindrical workpiece is clamped to the second positioning protrusion 21, completing the automatic clamping and positioning of the cylindrical workpiece. Then, the electric control cylinder 31 drives the transmission frame 32 and the sealing strip 33 to move towards the electric control slide 1, so that the sealing strip 33 enters the groove of the electric control slide 1. When the milling machine processes the cylindrical workpiece, the generated iron filings will not enter the interior of the electric control slide 1 through the groove, improving the sealing performance of the electric control slide 1. When the electric control slide 1 needs to be driven for adjustment, the electric control cylinder 31 drives the sealing strip 33 to slide out of the groove, without interfering with the movement trajectory of the electric control slide 1.

[0019] Example 2: Figure 1 - Figure 4As shown, the machining fixture for automatic clamping and positioning of parts in this utility model includes an electrically controlled slide table 1. A workpiece positioning fixture 11 is fixedly connected to the drive end of the electrically controlled slide table 1. A workpiece baffle 2 is fixedly connected to one end of the electrically controlled slide table 1. Slide groove sealing assemblies 3 are provided on both sides of the electrically controlled slide table 1. The slide groove sealing assembly 3 includes two sets of electrically controlled cylinders 31, a transmission frame 32, and a sealing strip 33. The drive ends of the two sets of electrically controlled cylinders 31 are fixedly connected to one end of the transmission frame 32, and the sealing strip 33 is located at the other end of the transmission frame 32. One end has several mounting grooves 321 arranged in a linear pattern. One side of the sealing strip 33 is fixedly connected with several threaded rods 331 arranged in a linear pattern. One end of the threaded rod 331 moves through the inside of the mounting groove 321 and is threaded with a nut. The end of the sealing strip 33 is movably fitted with a rubber sleeve 332. A positioning frame 34 is provided on the outside of the electric control cylinder 31. The inner side of the positioning frame 34 is attached to the outside of the electric control cylinder 31. The two ends of the positioning frame 34 are fixedly installed at the bottom edge of the electric control slide table 1 by bolts.

[0020] The overall effect of this embodiment is that when it is necessary to clamp cylindrical workpieces of different lengths, the clamping point at the drive end of the electrically controlled slide table 1 will change accordingly, at which point the sealing strip 33 needs to be replaced. The specific operation is as follows: first, remove the nut, then drag the sealing strip 33 so that its threaded rod 331 slides out from inside the mounting groove 321, remove the sealing strip 33 and replace it. Through this operation, the machining fixture that automatically clamps and positions the part can clamp cylindrical workpieces of different lengths, thereby expanding the range of workpiece types that the fixture can clamp.

[0021] The method of use and working principle of this device: One end of the cylindrical workpiece to be processed is clamped to the outside of the first positioning protrusion 112. Then, the electric control slide 1 is started. The drive end of the electric control slide 1 drives the workpiece positioning fixture 11 and the cylindrical workpiece to move towards the workpiece baffle 2, so that the other end of the cylindrical workpiece is clamped to the second positioning protrusion 21, completing the automatic clamping and positioning of the cylindrical workpiece. Then, the electric control cylinder 31 drives the transmission frame 32 and the sealing strip 33 to move towards the electric control slide 1, so that the sealing strip 33 enters the groove of the electric control slide 1.

[0022] When it is necessary to tighten cylindrical workpieces of different lengths, the tightening point at the drive end of the electrically controlled slide table 1 will change accordingly. At this time, the sealing strip 33 needs to be replaced. The specific operation is as follows: First, remove the nut, then drag the sealing strip 33 so that its threaded rod 331 slides out from inside the mounting groove 321, remove the sealing strip 33 and replace it.

[0023] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
